Ingredients
Method
- Preheat oven to 350°F (175°C). Grease two 8-inch round pans and line with parchment. Whisk together flour, sugar, cocoa, baking soda, baking powder, and salt.
- Make a well in the dry ingredients, add buttermilk, oil, eggs, and vanilla. Beat on medium 2 minutes. Slowly add hot coffee, mixing just until combined.
- Divide batter between pans and bake 30-35 minutes until a toothpick has moist crumbs. Cool in pans 10 minutes, then turn out onto a rack to cool completely.
- Beat the butter until fluffy, then gradually add powdered sugar. Beat in heavy cream and vanilla. Fold in crushed Oreos by hand.
- Place one cake layer on a plate, spread with frosting, and top with the second layer. Frost the top and sides, then decorate with halved Oreos or extra cookie crumbs.
Notes
Make the cake layers a day ahead and wrap them tightly. Frost just before serving. Store the finished cake in the fridge but let it come to room temperature for the creamiest bite.
