Ingredients
- Unsalted European-style butter
- Large egg whites
- Sour cream
- Whole milk
- All-purpose flour
- Granulated sugar
- Baking soda
- Baking powder
- Kosher salt
- Vanilla extract
- Dark cocoa biscuits (Oreos)
- Semisweet chocolate (60% cocoa)
- Heavy cream
- Confectioners’ sugar
Instructions
- Preheat oven to 350°F (175°C) and grease three 6-inch cake pans, using damp cake strips for the most even rise.
- Sift the flour, sugar, baking soda, baking powder, and salt into a large bowl to ensure a light, aerated crumb.
- Cream the room-temperature butter in a stand mixer for 3 minutes until pale and fluffy, then mix in the dry ingredients on low until the texture resembles coarse sand.
- In a separate bowl, whisk together the egg whites, sour cream, milk, and vanilla, then gradually incorporate into the mixer and beat for 60 seconds until glossy.
- Gently fold the chopped cookies into the batter by hand and divide the mixture evenly between the prepared pans.
- Bake for 25-30 minutes until the centers spring back, then cool in the pans for 10 minutes before transferring to a wire rack.
- Whip the butter for the frosting for 5 minutes, then add sugar and cream; reserve a small amount of white frosting before mixing crushed cookies into the remainder.
- Prepare the ganache by pouring simmered cream over chocolate, resting for 2 minutes, and whisking until emulsified and glossy.
- Assemble by layering the sponge with buttercream and ganache, apply a crumb coat and chill, then finish with the final frosting layer, ganache drips, and decorative dollops.
Notes
For the best structural integrity, ensure your cake layers are completely chilled before attempting to assemble and frost. Using a digital scale to weigh your batter into the pans will guarantee even layers that bake at the same rate, resulting in a more professional appearance.
