Instructions

Prepare the cookie dough filling: In a bowl, mix 1/2 cup unsalted butter, granulated sugar, light brown sugar, milk, vanilla extract, 2 cups all-purpose flour, salt, and mini chocolate chips until smooth. Set this mixture aside.
Preheat the oven: Set your oven to 350°F (175°C).
Make the cake batter: Cream together 1 1/2 cups unsalted butter and 2 cups sugar until fluffy. Add the eggs one at a time, mixing well after each addition, then stir in 2 tsp vanilla extract.
Combine dry ingredients: In a separate bowl, whisk together 3 cups all-purpose flour, baking powder, and 1 tsp salt.
Alternate mixing: Gradually add the dry mixture to the wet ingredients, alternating with whole milk and Greek yogurt. Mix until just combined, then fold in 1 cup mini chocolate chips.
Prepare cake pans: Grease three 8-inch round cake pans. Evenly divide the cake batter among them.
Add cookie dough topping: Drop spoonfuls of the prepared cookie dough filling on top of the batter in each pan.
Bake: Bake the cakes for about 30 minutes or until a toothpick inserted in the cake portion comes out clean. Let them cool completely.
Make the buttercream frosting: Beat 1 1/2 cups unsalted butter until creamy. Gradually add powdered sugar, milk, vanilla extract, light brown sugar, all-purpose flour, salt, and mini chocolate chips, beating well until smooth and fluffy.
Prepare the chocolate ganache: Heat heavy cream until just boiling, then pour over chopped bittersweet chocolate. Let sit for 2 minutes, then stir until smooth. Stir in vegetable oil for shine.
Assemble the cake: Layer the cooled cake rounds with the cookie dough buttercream between each layer. Frost the entire outside of the cake with the remaining buttercream.
Finish with ganache: Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides.

Tips & Variations

For extra texture, add chopped nuts like walnuts or pecans to the cookie dough filling.
Use white chocolate chips in the buttercream for a sweeter twist.
If you prefer, substitute Greek yogurt with sour cream for a similar tangy moisture.
Make sure not to overmix the batter to keep the cake light and tender.

Storage

Store the cake covered in the refrigerator for up to 4 days. Bring to room temperature before serving. Leftovers can be wrapped tightly and frozen for up to 2 months; thaw overnight in the fridge. Reheat slices gently in the microwave for a few seconds if desired.

FAQs

Can I use regular yogurt instead of Greek yogurt?

Yes, regular yogurt can be used but may result in a slightly less thick and tangy batter. Greek yogurt provides more richness and moisture.

Is it necessary to bake the cookie dough on top of the cake batter?

Baking the cookie dough on top helps it meld with the cake layers, creating a unique texture and flavor combination. You can skip it, but the cake will lack the signature cookie dough element.
