Step‑by‑Step Instructions for Decadent Brownie Cake with Chocolate Chip Cookie Dough Filling
Step 1: Prepare the pans
Spray four 9-inch round cake pans with non-stick spray and line the bottoms with parchment paper. This ensures your Decadent Brownie Cake layers release easily after baking. Set the prepared pans aside, ready for the brownie batter that’s up next.
Step 2: Heat treat the flour
Preheat your oven to 350°F (175°C). To eliminate any bacteria, spread the flour on a baking sheet and bake for 5-7 minutes, keeping an eye on it until it reaches 165°F. After removing it from the oven, allow the flour to cool completely before adding it to your cookie dough mixture.
Step 3: Make the brownies
Prepare the brownie batter according to the package instructions, stirring until smooth and combined. Pour the brownie mix evenly into the four prepared pans. Bake in the preheated oven for 20-25 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Once baked, let the brownies cool completely on a wire rack.
Step 4: Make the cookie dough
In a mixing bowl, combine the heat-treated flour and salt. In a separate bowl, cream together the softened butter, sugar, brown sugar, and vanilla extract until light and fluffy. Gradually add the flour mixture, mixing well, then incorporate the milk to reach a cookie dough consistency. Finally, fold in the chocolate morsels for that delightful surprise in your cookie dough layer.
Step 5: Assemble the cake
Begin assembling your Decadent Brownie Cake by placing the first brownie layer on a serving plate. Spread 1/3 of the prepared cookie dough evenly over this layer. Gently add the second brownie, top with half of the remaining cookie dough, then repeat with the third brownie, finishing with the last layer of cookie dough on top for a beautiful finish.
Step 6: Prepare the ganache
In a small saucepan, heat the heavy cream over medium heat until it just begins to boil. Remove from heat and pour it over the finely chopped dark chocolate in a heatproof bowl. Let it sit for a minute, then stir until the chocolate is fully melted and the ganache is smooth and glossy.
Step 7: Finish the cake
Carefully pour the rich ganache over the assembled brownie layers, allowing it to cascade down the sides for an elegant look. For added texture, sprinkle some finely chopped brownie on top. Your Decadent Brownie Cake with Chocolate Chip Cookie Dough Filling is now ready to be sliced and served, promising a delightful taste experience for everyone!

How to Store and Freeze Brownie Cake
Fridge: Store in an airtight container in the refrigerator for up to 3-5 days to maintain moisture and freshness. Each slice will remain deliciously tempting, making it a delightful treat whenever you crave dessert.
Freezer: For longer storage, wrap individual slices tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 2 months, ensuring you have a sweet surprise anytime!
Thawing: To enjoy your brownie cake, simply remove it from the freezer and let it thaw in the fridge overnight or at room temperature for about an hour before serving.
Reheating: If you prefer warm slices, gently reheat in the microwave for 10-15 seconds, just enough to warm up the fudgy layers without compromising the delightful textures.
Make Ahead Options
These Decadent Brownie Cakes with Chocolate Chip Cookie Dough Filling are a dream for meal prep enthusiasts! You can prepare the brownie layers up to 3 days in advance, simply wait for them to cool completely before wrapping each layer tightly in plastic wrap and refrigerating. The cookie dough can also be made ahead and stored in the fridge, covered, for up to 24 hours to let the flavors meld. When you’re ready to assemble, layer the brownies with the cookie dough and finish with the ganache, pouring it over just before serving to keep it fresh and glossy. This ensures your cake will be just as delicious and impressive on the day of the event while saving you precious time!
