The Foundation: A Flawless Vegan Brownie Cake
The base of this spectacular cake is a rich, dense, and utterly fudgy vegan brownie layer. While it shares some characteristics with my classic vegan chocolate cake, this particular recipe leans more into the deep, satisfying chewiness and intense chocolate flavor that defines a perfect brownie. It’s the ideal sturdy yet tender foundation to hold up the decadent layers of frosting.
The full, detailed recipe for the brownie cake layer can be found on Shanika’s blog, where she guides you through every step to achieve perfection. However, here are my essential tips to ensure your brownie cake layers are absolutely magnificent:
- Sift All Dry Ingredients: This step is often overlooked but is crucial for creating a light and airy cake texture. Sifting removes any lumps and ensures that your leavening agents (like baking soda or powder) are evenly distributed throughout the batter. This results in a consistent, uniform crumb and a better rise, preventing dense spots or pockets of unincorporated flour.
- Use Room Temperature Wet Ingredients: The temperature of your ingredients significantly impacts the consistency and emulsion of your batter. When wet ingredients like vegan butter and dairy-free milk are at room temperature, they combine more smoothly and efficiently with dry ingredients. This creates a more cohesive, stable batter, which in turn leads to a tender and moist cake. Cold ingredients can cause the batter to curdle or become lumpy.
- Lightly Tap Cake Pans: After pouring the batter into your prepared cake pans, gently tap them a few times on your countertop. This simple action helps to release any trapped air bubbles from the bottom and sides of the batter. Removing these air pockets prevents large holes or tunnels from forming in your baked cake layers, ensuring a dense, even, and beautifully uniform texture throughout.
- Do Not Overmix: Overmixing can develop the gluten in the flour too much, leading to a tough and rubbery cake. Mix only until the ingredients are just combined. A few small lumps are perfectly fine.
- Proper Cooling: Once baked, allow the cake layers to cool in their pans on a wire rack for about 10-15 minutes before inverting them onto the rack to cool completely. This prevents the delicate cake from breaking and allows it to firm up.
With these tips, your vegan brownie cake layers will be the perfect starting point for our extraordinary dessert. Now, let’s dive into the star of the show: the vegan cookie dough batter frosting!
The Star: Vegan Cookie Dough Batter Frosting
Without a doubt, my favorite component of this vegan brownie cookie dough cake is the incredible cookie dough frosting. It’s a revelation – tasting quite literally like a spoonful of raw cookie dough, transformed into a luxurious, spreadable frosting. It captures all the nostalgic joy and irresistible flavor of your favorite cookie dough, but in a safe, egg-free, and utterly delicious form.
The primary difference between this frosting and traditional edible vegan cookie dough lies in its consistency, adapted perfectly for layering a cake. We use a slightly higher butter-to-flour ratio to achieve a creamier, more spreadable texture, ideal for frosting. Additionally, the incorporation of powdered sugar, alongside coconut sugar, contributes to its smooth volume and delightful sweetness, creating a truly fluffy and rich frosting.

The full, detailed recipe for the cookie dough frosting is included below in the recipe card, but here’s a breakdown of the key ingredients and why they’re essential:
- Vegan Butter: Essential for the rich, creamy base of our frosting. Ensure it’s softened to room temperature, not melted. This allows it to cream properly and incorporate air, resulting in a light and fluffy texture.
- Powdered Sugar: Provides sweetness and, crucially, adds volume and stability to the frosting, giving it that classic buttercream-like consistency. Sifting it will prevent lumps.
- Coconut Sugar: Used much like brown sugar in traditional cookie dough, coconut sugar contributes a deeper, caramel-like sweetness and a slight chewiness, enhancing the authentic cookie dough flavor profile.
- All-Purpose Flour: This is what gives the frosting its distinct “dough” texture. It is absolutely vital that the flour is **toasted and cooled** before use. Toasting the flour (by spreading it on a baking sheet and baking at 300°F/150°C for about 5-7 minutes, then cooling completely) eliminates any potential bacteria, making the cookie dough safe to eat raw. This step cannot be skipped!
- Vanilla Extract: A classic flavor enhancer that brings warmth and depth to the cookie dough taste.
- Dairy-Free Milk: Used sparingly, just a tablespoon or two, to achieve the perfect consistency for spreading. Add it gradually until the frosting is smooth and workable.
- Vegan Chocolate Chips: The iconic addition to any cookie dough! Choose your favorite brand of dairy-free chocolate chips to fold into the frosting, adding bursts of chocolatey goodness throughout.
The process of making this vegan cookie dough frosting is quite similar to preparing our vegan chocolate buttercream. You’ll begin by creaming the softened vegan butter until it’s light and fluffy. Then, gradually sift in the powdered sugar, toasted flour, coconut sugar, and vanilla extract, continuing to beat until the mixture transforms into a wonderfully smooth and voluminous frosting. Finally, gently fold in those irresistible vegan chocolate chips, ensuring they are evenly distributed throughout the creamy dough.
Expert Tips & Tricks for Cookie Dough Cake Success
Achieving a truly spectacular vegan brownie cookie dough cake is easy with these helpful tips and tricks:
- Ensure Complete Cooling: This is perhaps the most critical step. Your brownie cake layers must be completely, utterly cool before you even think about frosting them. Warm cake will melt your beautifully prepared cookie dough frosting, leading to a messy and unstable cake. Patience is key here! You can even bake the layers a day ahead and store them wrapped at room temperature.
- Smooth Frosting Application: For neat layers, use an offset spatula to spread an even amount of cookie dough frosting between each cake layer. Don’t press down too hard on the cake layers as you assemble; let the frosting do the work. For the final chocolate buttercream exterior, a smooth crumb coat (a thin layer of frosting that traps crumbs) applied first and chilled, will ensure a perfectly pristine finish.
- Can I make this vegan layer cake into cupcakes? Absolutely! This recipe is wonderfully versatile. You can easily adapt the brownie cake batter to make delicious cupcakes. Simply fill cupcake liners about two-thirds full and bake for approximately 25-28 minutes, or until a toothpick inserted into the center comes out clean. Once cooled, you can core each cupcake and fill it with the vegan cookie dough frosting, then pipe vegan chocolate buttercream on top for a miniature version of this stunning cake. This is a fantastic option for parties or individual servings.
- How to store this cookie dough cake: This cake stores beautifully. If you have any extra slices, the best way to keep them fresh is to place them in an airtight storage container. If storing the whole cake, a cake container is ideal. Refrigerate the cake to maintain its structure and freshness, especially due to the vegan butter in the frostings. It will keep well in the fridge for up to 5-7 days. For longer storage, slices can be individually wrapped in plastic wrap and then foil, and frozen for up to 1 month. Thaw in the refrigerator before serving.
- Quality of Ingredients: Using high-quality vegan butter and chocolate chips will significantly impact the final flavor and texture of your cake. Invest in good-quality ingredients where possible for the best results.
- Toasting Flour Safety: As mentioned, always toast your flour for the cookie dough frosting. This critical step ensures food safety by eliminating any potential raw flour pathogens. It’s a quick process that makes all the difference in enjoying your raw-tasting frosting worry-free.

Description
This vegan brownie cookie dough cake is the ultimate indulgence! It’s a brownie chocolate cake layered with vegan cookie dough frosting, and topped with bite-sized cookie dough bites!
Ingredients
Chocolate Brownie Cake Layer
- Please refer to Orchids + Sweet Tea for the full brownie cake recipe.
Vegan Cookie Dough Frosting:
- 1 cup vegan butter, softened to room temperature
- 1 cup all-purpose flour, toasted and cooled (see tips for toasting)
- ¾ cup coconut sugar
- 3 cups powdered sugar, sifted
- 1 tsp vanilla extract
- 2-3 tbsp dairy-free milk (as needed for consistency)
- ¾ cup vegan-friendly chocolate chips
Vegan Chocolate Buttercream:
- 1 cup vegan butter, softened to room temperature
- 3 cups powdered sugar, sifted
- 1 cup cacao powder
- 2-4 tbsp dairy-free milk (as needed for consistency)
Instructions
- Follow the directions for the vegan brownie cake layer until the cakes are fully baked and completely cooled.
- Once the cake layers are cool, prepare both the vegan chocolate buttercream and the vegan cookie dough buttercream according to the instructions below.
- Vegan Cookie Dough Buttercream: In a large mixing bowl, beat the softened vegan butter until light and creamy, about 3 minutes. Gradually sift in the powdered sugar, toasted and cooled flour, coconut sugar, and vanilla extract. Continue beating until the mixture becomes a fluffy, smooth buttercream. If the frosting is too thick, add dairy-free milk one tablespoon at a time until the desired spreading consistency is achieved. Gently fold in the vegan chocolate chips until evenly distributed.
- Vegan Chocolate Buttercream: In a separate bowl, beat the softened vegan butter until creamed and fluffy, approximately 3 minutes. Gradually sift in the powdered sugar and continue beating until combined and smooth. Add the cacao powder, starting by gently beating it into the center of the mixture to prevent a dust cloud, then fully incorporate it into the buttercream until it is uniformly rich and chocolatey. Add dairy-free milk as needed to reach a pipeable or spreadable consistency.
- Assemble the cake: Place one cooled brownie cake layer on your serving plate or cake stand. Spread an even layer of the vegan cookie dough buttercream frosting over the top. Carefully place the second cake layer on top, then spread another layer of cookie dough frosting. Finally, use the vegan chocolate buttercream frosting to generously coat the outside of the entire cake, smoothing the sides and top with an offset spatula. Decorate with additional cookie dough bites or chocolate chips if desired.
- Serve slices of your magnificent vegan brownie cookie dough cake and enjoy this incredible treat!
