The Method for Double Chocolate Cookie Layer Cake

Now, let’s get into the delicious details of making this Double Chocolate Cookie Layer Cake!
Step 1: Prepare the Cookie Dough
In a mixing bowl, cream together the softened unsalted butter and brown sugar until light and fluffy. This should take about 2-3 minutes. Add the vanilla extract and egg, beating until well combined.
Step 2: Mix the Dry Ingredients
In a separate bowl, whisk together the plain flour, baking soda, cornflour, and a pinch of salt. Gradually add this mixture to the wet ingredients, mixing until just combined. Fold in the chocolate chips.
Step 3: Bake the Cookie Layers
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper. Using a cookie scoop, drop rounded tablespoons of the cookie dough onto the prepared sheets, spacing them a couple of inches apart. Bake for 10-12 minutes or until the edges are golden but the centers are still soft. Allow to cool on the sheets for a few minutes before transferring to a wire rack to cool completely.
Step 4: Prepare the Cake Batter
In another mixing bowl, combine the plain flour, cocoa powder, baking soda, and baking powder. Set aside. In a large bowl, cream the unsalted butter with the brown and caster sugars until light and fluffy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Step 5: Combine Wet and Dry Ingredients
Alternately add the dry ingredient mixture and buttermilk to the butter and sugar mixture, starting and ending with the dry ingredients. Mix until just combined—do not overmix.
Step 6: Bake the Cake Layers
Divide the cake batter evenly between your prepared cake pans. Smooth the tops with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cake layers cool in the pans for 10 minutes before inverting onto a wire rack to cool completely.
Step 7: Make the Frosting
In a large mixing bowl, beat the room temperature butter until creamy. Gradually add in the icing sugar and cocoa powder, mixing on low speed until combined. Once incorporated, add the milk 1 tablespoon at a time until you reach the desired consistency for spreading.
Step 8: Assemble the Cake
Once the cake and cookie layers are completely cool, it’s time to assemble! Place one cake layer on a serving plate. Spread a layer of frosting on top, followed by a layer of cookies. Repeat with the second cake layer and top with frosting. Decorate with additional cookies if desired.
Step 9: Serve and Enjoy!
Slice your Double Chocolate Cookie Layer Cake and serve it to your eager family and friends. Watch as their eyes light up and they savor every bite!
In-Season Swaps

Feel free to get creative with this recipe! Here are some suggestions for seasonal swaps:
- Try using pumpkin puree instead of buttermilk for a fall twist.
- Incorporate mint extract into the frosting for a refreshing mint chocolate flavor.
- Add chopped nuts like walnuts or pecans for extra crunch in the cookie layers.
- Substitute dark chocolate chips for semi-sweet for a richer chocolate experience.
Little Things that Matter
As with any baking endeavor, attention to detail can make a big difference in the final product. Here are a few tips to keep in mind:
- Make sure your ingredients are at room temperature for better incorporation.
- Don’t skip the cooling time for the baked layers; frosting a warm cake can lead to a melty mess.
- Use high-quality cocoa powder and chocolate chips for the best flavor.
- Feel free to adjust the sweetness of the frosting by adding more or less icing sugar to suit your taste.
