Jump to Recipe
Prepare yourself for an extraordinary dessert experience with this incredible Brownie Cookie Dough Cake. This isn’t just a cake; it’s a celebration of all things fudgy, chocolatey, and delightfully doughy. Imagine sinking your teeth into layers of intensely rich, fudgy chocolate brownie, generously studded with luscious milk chocolate chips. Nestled between these decadent brownie layers is a thick, irresistible blanket of edible brown butter cookie dough, offering a sweet, nutty, and wonderfully chewy contrast. The entire masterpiece is then enrobed in a velvety smooth Russian buttercream, packed with delightful chunks of the same brown butter cookie dough, and crowned with extra scoops of cookie dough on top for that ultimate textural and flavor explosion. This cake is truly indulgent, creamy, chocolatey, and boasts a delightful crunch that will leave you craving more. Designed to create one magnificent 8-inch round, double-layered cake, it’s perfect for any special occasion or simply to treat yourself to an unforgettable dessert.
Crafting the Decadent Layers
The foundation of this exceptional cookie dough brownie cake lies in its two layers of utterly decadent, fudgy brownies. These aren’t your average cake layers; they are rich, dense, and moist, infused with deep chocolate flavor and studded with your favorite chocolate chips. I personally love the smooth sweetness that milk chocolate chips bring to the brownies, creating a harmonious balance with the fudgy base. However, feel free to customize! You can easily swap them out for semisweet chocolate chips, which offer a slightly more intense chocolate flavor, or even chopped dark chocolate for a truly gourmet touch. For those who enjoy added texture and flavor, consider incorporating chopped nuts such as walnuts or pecans, or even other fillings like caramel bits or dried fruit into the brownie batter before baking. This flexibility allows you to tailor the brownie layers to your exact preferences, making each bite uniquely yours.
But the true star of the show, arguably, is the thick, luscious layer of edible brown butter cookie dough that forms the delightful heart of this cake. This isn’t just any cookie dough; it’s a meticulously crafted, egg-less recipe that delivers the authentic, addictive taste and thick texture of real cookie dough, made completely safe for raw consumption thanks to pasteurized flour. The secret ingredient here is the brown butter, which transforms simple cookie dough into something extraordinary. Browning the butter unlocks a depth of flavor, adding a wonderfully toasty, nutty aroma that elevates the entire cake. If you haven’t yet discovered the magic of brown butter, this cake offers the perfect introduction. Its warm, caramel-like notes perfectly complement the rich chocolate brownies and creamy frosting, creating a symphony of flavors and textures in every slice. You can even make an extra batch of this irresistible cookie dough to adorn the top of your finished cake with delightful scoops, adding to its visual appeal and ensuring an extra hit of that beloved raw cookie dough experience.

The Silky Cookie Dough Buttercream Frosting
No magnificent cake is complete without an equally impressive frosting, and this cookie dough fudgy brownie cake features a truly special one: a super creamy, luscious, and incredibly simple two-ingredient Russian buttercream. This unique frosting is crafted from just two core ingredients: butter and sweetened condensed milk. The magic happens when these two are combined. The sweetened condensed milk lends a distinctive, beautifully milky flavor and a luxurious smoothness that perfectly marries with the richness of the brownie layers and the sweet, nutty notes of the cookie dough. It evokes the nostalgic comfort of “milk and cookies” in every bite, making it an ideal pairing for this particular cake.
To achieve the perfect consistency, the butter is first creamed extensively until it transforms into an incredibly light and fluffy cloud. This process ensures the buttercream will be airy and smooth, rather than dense or greasy. A touch of pure vanilla extract is then incorporated, followed by the sweetened condensed milk, added gradually to ensure a seamless emulsion. The mixture whips up into an irresistibly smooth and pipeable frosting. A small portion of this pristine buttercream is set aside to create elegant borders or decorations on the finished cake, providing a clean contrast. To elevate the frosting to its cookie-dough-infused glory, room temperature edible cookie dough is gently folded into the remaining buttercream. It’s crucial to mix this in very briefly, just until combined, allowing the cookie dough to remain in delightful, noticeable chunks. These chunks are key; they provide bursts of flavor and a wonderful chewy texture that enhances the overall experience of the cake. A clever adjustment in this recipe involves using slightly less sweetened condensed milk than a standard Russian buttercream. This subtle reduction ensures that once the sweet cookie dough is added, the frosting doesn’t become overwhelmingly sweet, maintaining a perfectly balanced indulgence.

Creating perfectly fudgy brownie layers is an art, but one that is easily mastered by paying attention to a few key details outlined in the recipe. Firstly, accurate measurement of your flour is paramount. While a measuring cup can be used, for optimal fudginess, it’s highly recommended to weigh your flour using a kitchen scale. If you’re using a measuring cup, ensure you measure it correctly: gently stir the flour in its bag or container, then spoon it lightly into the measuring cup without packing it down. Finally, level off the top with the flat edge of a knife. This prevents over-measuring, which can lead to a drier, more cake-like texture. Secondly, resist the urge to overmix the batter once the flour is added. Mix just until all the dry ingredients are barely incorporated. Excessive mixing develops too much gluten, transforming your fudgy brownies into a more traditional cakey consistency. Lastly, and perhaps most crucially, avoid overbaking. You want to remove the brownie layers from the oven when their centers are still slightly jiggly and the edges are just set. Remember, brownies continue to cook from residual heat as they cool, so pulling them out a little early will lock in that desirable moist, fudgy texture. Trust the jiggle for supreme fudginess!
Serving this magnificent cake at room temperature is absolutely essential for experiencing it at its very best. This recipe, much like many rich desserts, relies heavily on butter in all its components – from the brownie layers themselves to the edible cookie dough and the luxurious buttercream frosting. When butter is cold, it firms up considerably, which can make the brownie layers denser, the cookie dough stiff, and the buttercream hard and unyielding. Allowing the cake to come to room temperature softens the butter throughout, transforming the brownie layers into their intended fudgy, moist state. The cookie dough becomes perfectly chewy, and the buttercream returns to its silky, spreadable, and creamy consistency. This ensures that every forkful is soft, moist, and lusciously smooth, offering the most delightful and melt-in-your-mouth experience possible. Patience is key for peak enjoyment!
The secret to a perfect, soft cookie dough buttercream lies in careful technique and the right butter consistency. Start with very soft butter – it should yield easily to a gentle press, but not be melted or greasy. Leave your butter out at room temperature for at least one to two hours before you begin. Once softened, beat the butter vigorously with a stand mixer or a powerful handheld electric mixer. This step is critical and should take a minimum of 5 minutes. You’ll observe the butter transforming; it will become significantly lighter in color, incredibly fluffy, and notably increase in volume. Next, gradually incorporate the room temperature sweetened condensed milk into the beaten butter. This gradual addition, combined with continuous beating, is vital to prevent the frosting from splitting and ensure it comes together smoothly. Continue beating for another 5 minutes after all the condensed milk has been added; this will make the frosting even lighter and fluffier. Finally, gently add the room temperature cookie dough to the frosting. Mix quickly, just enough to combine, ensuring the cookie dough remains in large, delightful chunks for textural contrast. Before frosting the cake, give the buttercream a few folds with a spatula to eliminate any large air pockets, which helps in smooth application. If you’re not frosting immediately, store the buttercream at room temperature for a few hours; it’s best used when soft and creamy.
Don’t panic if your buttercream frosting appears to split or look curdled – it’s a common issue and easily fixable! This usually happens when the butter and condensed milk are at different temperatures or haven’t emulsified properly. To remedy this, take approximately a quarter cup of the split frosting and gently melt it down. You can do this either in a double boiler (a heatproof bowl placed over a pot of simmering water, ensuring the bowl doesn’t touch the water) or carefully in the microwave in 10-second intervals, stirring in between. Once melted, allow this small portion of frosting to cool back down to room temperature. It’s crucial that it’s not hot when you add it back. Pour the cooled, melted frosting back into the main bowl of split frosting. Then, beat the entire mixture thoroughly and vigorously with your stand mixer or electric handheld mixer. Continue beating until it transforms back into a light, fluffy, and perfectly smooth consistency. This technique usually re-emulsifies the butter and condensed milk, bringing your frosting back to life.
Absolutely! This cake is perfect for making ahead, which can help streamline your baking process, especially for events. The individual brownie layers are very forgiving and can be baked a day or two in advance. Once fully cooled, wrap each layer tightly with plastic wrap to prevent them from drying out, and store them at room temperature until you’re ready to assemble. For the frosting, it’s generally best to prepare the full cookie dough buttercream on the day you plan to frost the cake. However, if you’re truly pressed for time, you can make the Russian buttercream base (butter, condensed milk, vanilla) the day before. Just be sure to omit the cookie dough at this stage. Refrigerating the buttercream base will alter its texture, making it firm. On the day of assembly, allow the refrigerated buttercream base to come to full room temperature, then beat it extensively until it regains its light and fluffy texture before gently folding in the cookie dough chunks. The frosting can then sit at room temperature for a few hours before use. The entire cake can also be assembled the day before serving. After assembly, store the cake in the refrigerator. To protect it and keep it moist, you can either place a large bowl upside down over the cake or wrap it carefully with cling film. Remember, for the best texture and flavor, always allow the assembled cake to come to room temperature before slicing and serving.

Essential Ingredients for Your Cake:
You’ll find the complete list of ingredients and detailed steps in the recipe card located below.
For the Fudgy Brownie Cake Layers:
- All-purpose flour: Crucial for the structure, precise measurement by weight ensures the perfect fudgy, dense texture rather than a cakey one.
- Baking soda: A small amount provides just enough lift to the brownies without making them overly airy, preserving that coveted fudgy chewiness.
- Salt: This unsung hero deepens the chocolate flavor, balances the sweetness, and enhances all the other ingredients, making it absolutely essential. Don’t skip it!
- Natural cocoa powder: Opt for natural cocoa powder, not Dutch-processed, in this recipe. Its natural acidity reacts with the baking soda to create a richer, more complex chocolate flavor profile.
- Unsalted butter: Melted butter contributes essential moisture and a rich flavor to the brownie batter. Always use high-quality real butter for the best results.
- Brown sugar and granulated sugar: The combination is key. Brown sugar adds a lovely molasses flavor and ensures moisture, while granulated sugar contributes to the classic crackly top and chewy texture of the brownies.
- Large eggs (room temperature): Eggs bind the ingredients, provide moisture, and add to the overall body and richness, which are vital for truly fudgy and decadent layers.
- Pure vanilla extract: Don’t skimp on quality here. Pure vanilla extract offers the most authentic and robust vanilla flavor, complementing the chocolate beautifully.
- Chocolate chips: Your choice! Milk chocolate chips lend a sweeter, creamier note, as used in this recipe. Semisweet chocolate chips are also an excellent option if you prefer a slightly less sweet brownie, or feel free to use your favorite chopped chocolate.
For the Luxurious Cookie Dough Buttercream:
- Unsalted butter, softened: The butter must be very soft – but not melted – to ensure it whips up into an incredibly light, airy, and fluffy frosting with perfect consistency.
- Sweetened condensed milk: This key ingredient gives the buttercream its signature milky flavor and smooth, luxurious texture. You’ll typically find it in cans at most grocery stores; one 300 mL (390 g or 14 oz by weight) can is needed.
- Pure vanilla extract: A generous dash of pure vanilla extract enhances the overall flavor of the frosting, making it wonderfully aromatic and delicious.
- Mini chocolate chips: These are added both into the buttercream for an extra pop of crunch and flavor, and also for decorating the sides of the cake, adding visual appeal and textural contrast.
Edible Brown Butter Cookie Dough: You will need one full batch of my edible brown butter chocolate chip cookie dough recipe. Half of this batch will form the glorious thick layer between your brownie cakes, and the other half will be mixed into your buttercream. For an optional, extra impressive topping with delightful scoops of cookie dough, you might consider preparing an additional half batch.
Step-by-Step Guide to Baking Perfection:
Crafting the Fudgy Brownie Cake Layers:
- Preheat your oven to 175°C (345°F) and prepare two 7-inch or 8-inch round cake pans by greasing them thoroughly with butter or oil and lining the bottoms with parchment paper. This ensures easy release.
- Gently melt the unsalted butter in a saucepan over low heat or in the microwave (stirring frequently to prevent scorching) until it’s completely liquid. Set it aside to cool down to room temperature.
- In a medium bowl, sift together your all-purpose flour, baking soda, salt, and natural cocoa powder. Sifting helps to remove any lumps and ensures the dry ingredients are evenly distributed. Set this mixture aside.
- In a separate, larger bowl, combine the brown sugar, granulated sugar, large room temperature eggs, and pure vanilla extract. Whisk these ingredients vigorously until the mixture is very smooth, significantly lighter in color, and slightly thickened. This aeration is important for the brownie’s texture.
- Once the melted butter has cooled, gradually whisk it into the egg and sugar mixture until everything is thoroughly combined and smooth.
- Now, gently fold in the sifted flour mixture and the chocolate chips into the wet ingredients. Mix just until no dry streaks of flour remain. Be very careful not to overmix, as this can lead to tough, cakey brownies.
- Divide the batter evenly between your two prepared cake tins. Bake for approximately 25-30 minutes. The brownie layers should still have a slight jiggle in the center when gently shaken, while the edges appear set. This is crucial for fudginess! Remove from the oven and allow them to cool completely in their pans on a wire rack. They will firm up as they cool and naturally sink slightly in the middle, creating a perfect well for the cookie dough.

Preparing the Creamy Cookie Dough Buttercream:
- Using a stand mixer fitted with a paddle attachment or a handheld electric mixer, beat the very softened butter on medium-high speed. This crucial step should take at least 5 minutes, ensuring the butter becomes incredibly light in color, remarkably fluffy, and increases significantly in volume.
- Once the butter is light and fluffy, add the pure vanilla extract and continue to beat until it is fully incorporated into the butter.
- With the mixer running on low speed, gradually pour in the room temperature sweetened condensed milk. Increase the speed to medium-high and beat vigorously until the frosting is completely smooth, luscious, and well-emulsified. Continue beating for at least another 5 minutes to achieve optimal fluffiness.
- After beating, use a spatula to fold the buttercream a few times. This helps to eliminate any large air pockets that might have formed during the beating process, resulting in a smoother application.
- If you plan to pipe a clean border around your cake, set aside about ½ cup of this plain buttercream. This portion will not have cookie dough chunks, allowing for precise piping.
- To the remaining buttercream, add the mini chocolate chips and half of your prepared edible brown butter cookie dough. Mix on low speed just until the cookie dough and chocolate chips are barely incorporated. The goal is to keep distinct chunks of cookie dough throughout the frosting, providing a delightful textural surprise in every bite.
Assembling Your Masterpiece:
- To begin the assembly, spread a small dollop of the prepared buttercream onto your cake board or serving stand. This acts as an anchor to prevent the cake from sliding. Carefully center and place your first cooled brownie cake layer on top. Don’t worry about perfectly even edges; the slightly sunken middle of the brownie layers actually creates a perfect natural cavity for your generous cookie dough filling.
- Now, take the second half of your edible brown butter cookie dough batch and spread it evenly over the first brownie layer, filling that lovely depression. On top of this rich cookie dough layer, add a generous amount of your cookie dough buttercream and gently smooth it out to create an even, delectable layer.
- Carefully place the second brownie cake layer on top, ensuring its bottom side is facing upwards. This provides a flatter, more stable surface for frosting. Gently press down on the cake to secure the layers. Using an offset spatula or bench scraper, generously spread the remaining cookie dough buttercream over the top and all sides of the cake. Take your time to smooth it out as much as possible for a polished finish. For an extra touch of decadence and crunch, gently press the remaining mini chocolate chips onto the sides of the cake.
- If you set aside some plain buttercream earlier, now is the time to use it. Transfer it to a piping bag fitted with your desired nozzle and pipe a beautiful border along the top edge of the cake. This creates a clean, professional finish.
- For the ultimate indulgence, decorate the top of your cake with additional scoops of edible cookie dough. This step is optional but highly recommended for an eye-catching presentation and an extra burst of cookie dough goodness. Once decorated, your magnificent Fudgy Brownie Cookie Dough Cake is ready to be sliced and served! Enjoy every single incredible bite.

Notes
Serving and Storing Your Cake:
For the absolute best experience, always serve this cake at room temperature. This allows the brownie layers to retain their irresistible fudgy texture and ensures the buttercream remains wonderfully soft and creamy, making every bite melt-in-your-mouth delicious.
Leftovers can be stored in the refrigerator, covered tightly, for up to 5 days. For longer storage, this cake freezes beautifully! Place any leftover slices or the entire remaining cake in an airtight container or a freezer-safe bag, and it will keep well for up to three months. Thaw in the refrigerator overnight and bring to room temperature before enjoying.
Making This Cake Ahead of Time:
The brownie cake layers are excellent for making in advance. Bake them a day or two before assembly. Once completely cooled, wrap each layer tightly with plastic wrap to maintain their moisture and store them at room temperature.
For the frosting, it’s generally recommended to prepare the full cookie dough buttercream on the day you plan to frost the cake. However, if you’re looking to save time, you can prepare just the Russian buttercream base (butter, sweetened condensed milk, vanilla) the day before. It’s crucial *not* to add the cookie dough at this stage. Refrigeration will cause the buttercream base to firm up and its texture to change. On the day of frosting, allow the refrigerated buttercream base to come to full room temperature. Then, beat it very well with a mixer until it is light and fluffy again, before gently folding in the cookie dough chunks. The prepared cookie dough buttercream can be left at room temperature for a few hours until you are ready to frost your cake.
The entire cake can be assembled the day before your event. Once assembled, store it in the refrigerator. To protect it from drying out and absorbing fridge odors, cover it with a large bowl placed upside down over the cake or wrap it thoroughly with cling wrap. Just remember to allow the assembled cake to come to room temperature for at least 1-2 hours before slicing and serving to ensure the best texture and flavor!
Expert Tips for Ensuring Fudgy Brownie Layers:
- Accurate Flour Measurement: Always weigh your flour with a digital kitchen scale for the most precise measurement. If using measuring cups, stir the flour in its container, then spoon it into the cup and level with a straight edge without packing.
- Do Not Overmix: Once you add the dry ingredients to the wet, mix only until the flour streaks disappear. Overmixing develops gluten, leading to tougher, cake-like brownies instead of fudgy ones.
- Avoid Overbaking: This is the golden rule for fudgy brownies. Remove the brownie layers from the oven when their centers are still slightly jiggly and the edges are just set. They will continue to cook from residual heat as they cool.
Troubleshooting Your Frosting:
If your buttercream frosting appears to split or remains lumpy even after extended beating, don’t despair! This is a common issue with an easy fix. Take about a quarter cup of the split frosting and gently melt it in a water bath (by placing the bowl in a larger bowl of hot water) or in the microwave in short bursts, stirring frequently. Allow this melted portion to cool back to room temperature. Once cooled, add it back into the main bowl of split frosting and beat the entire mixture vigorously with your mixer. Continue beating until it becomes light, fluffy, and perfectly smooth again. This technique helps re-emulsify the ingredients, bringing your frosting back to its intended consistency.
