1/4 cup (60ml) milk (for buttercream frosting)
2 tsp vanilla extract (for buttercream frosting)
1/2 tsp salt (for buttercream frosting)
1/2 cup (90g) mini chocolate chips (for buttercream frosting)
4 oz bittersweet chocolate, chopped (for ganache)
4 oz (1/2 cup) heavy cream (for ganache)
2–3 tsp vegetable oil (for ganache)

Instructions

Step 1: Prepare the cookie dough filling by mixing 1/2 cup unsalted butter, 1/2 cup granulated sugar, 2/3 cup light brown sugar, 1/4 cup milk, 2 tsp vanilla extract, 2 cups all-purpose flour, 1/2 tsp salt, and 1 cup mini chocolate chips until smooth. Set aside.
Step 2: Preheat your oven to 350°F (175°C). In a large bowl, cream together 1 1/2 cups unsalted butter and 2 cups sugar until fluffy. Add eggs one at a time, mixing well after each addition, then stir in 2 tsp vanilla extract.
Step 3: In another bowl, whisk together 3 cups all-purpose flour, 2 tsp baking powder, and 1 tsp salt. Gradually add the dry ingredients to the wet mixture, alternating with 1 cup whole milk and 1/2 cup Greek yogurt, starting and ending with flour mixture. Fold in 1 cup mini chocolate chips.
Step 4: Grease three 8-inch round cake pans. Divide the batter evenly among them. Drop spoonfuls of the prepared cookie dough filling onto the batter in each pan. Bake for about 30 minutes or until a toothpick inserted in the cake comes out clean. Allow cakes to cool completely.
Step 5: For the buttercream frosting, beat 1 1/2 cups unsalted butter until creamy. Gradually add 5 cups powdered sugar while mixing, then add 1/4 cup milk, 2 tsp vanilla extract, 3/4 cup light brown sugar, 1 cup all-purpose flour, 1/2 tsp salt, and 1/2 cup mini chocolate chips. Beat until well combined and smooth.
Step 6: Assemble the cake by layering the cooled cakes with cookie dough buttercream in between each layer. Frost the outside of the cake with remaining buttercream.
Step 7: To make the chocolate ganache, heat 4 oz bittersweet chocolate with 4 oz heavy cream and 2–3 tsp vegetable oil until smooth and glossy. Pour over the top of the cake and let set before serving.

Tips & Variations

Use room temperature ingredients to ensure smooth mixing and better texture.
Mini chocolate chips work best to evenly distribute in the batter and frosting.
For a richer ganache, add a teaspoon of espresso powder to enhance the chocolate flavor.
Substitute Greek yogurt with sour cream if you prefer a tangier cake.
Make the cookie dough filling a day ahead to let the flavors meld.

Storage

Store the assembled cake covered in the refrigerator for up to 4 days. Bring to room temperature before serving for the best flavor and texture. The cake can also be frozen for up to 2 weeks; thaw overnight in the refrigerator and allow to come to room temperature before serving. Avoid storing the cake at room temperature for extended periods because of the dairy ingredients in the filling and frosting.

How to Serve

FAQs

Can I use regular chocolate chips instead of mini chips?

Yes, but mini chocolate chips distribute more evenly throughout the batter and frosting, giving a better texture and bite.

Is it safe to eat the cookie dough filling without baking?

This recipe is designed for baking, but since the filling contains raw flour and butter, it’s best to bake it within the cake for safety. If you want to eat raw cookie dough, use heat-treated flour and consider omitting eggs.
