Ingredients
Scale
- 2 cups all-purpose flour
- 1 ¾ cups granulated sugar
- ¾ cup Dutch-processed cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 2 large eggs
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 tsp vanilla extract
- 1 cup hot brewed coffee
2. For the Oreo Buttercream:
- 1 ½ cups unsalted butter, softened
- 5 cups powdered sugar
- ¼ cup heavy cream
- 2 tsp vanilla extract
- 15 Oreo cookies, coarsely crushed
3. For the Ganache:
- 1 cup semi-sweet chocolate chips
- 1 cup heavy cream
3. Decoration:
- Whole Oreos for topping
- Sprinkles (optional)
Instructions
- Preheat oven to 350°F. Grease and line three 8-inch round pans with parchment.
- Whisk flour, sugar, cocoa, baking soda, baking powder, and salt.
- In another bowl, whisk eggs, buttermilk, oil, and vanilla. Slowly stir in hot coffee. Batter will be thin.
- Divide batter into pans. Bake 28–32 minutes, or until a toothpick comes out clean. Cool completely.
- For frosting: beat butter until fluffy. Gradually add powdered sugar, then cream and vanilla. Fold in crushed Oreos gently.
- For ganache: heat cream until steaming, pour over chocolate chips, stir until glossy. Cool slightly.
- Assemble: layer cake with frosting between each tier. Apply crumb coat, chill, then frost smoothly.
- Drizzle cooled ganache along edges, letting it drip. Top with Oreos and sprinkles.
Notes
- For extra crunch, press crushed Oreos around the cake’s base.
- To make it less sweet, reduce powdered sugar in the frosting by ½ cup.
- Always chill the cake briefly after crumb coating—it makes the final finish easier.
