Ingredients:
- 2.5 cups (315g) all-purpose flour
- 1.5 cups (300g) granulated sugar
- 1 tbsp (12g) baking powder
- 0.5 tsp (3g) salt
- 0.75 cup (170g) unsalted butter, softened
- 3 large eggs (150g)
- 1 cup (240ml) whole milk
- 2 tsp (10ml) pure vanilla extract
- 1 cup (115g) crushed Oreo cookies (coarse crumbs)
- 1.5 cups (340g) unsalted butter, softened
- 5 cups (600g) powdered sugar
- 3 tbsp (45ml) heavy cream
- 1 tsp (5ml) vanilla extract
- 0.75 cup (85g) Oreo cookies, pulsed into a fine dust
- 10 whole Oreo cookies
- 0.5 cup (120ml) heavy cream
- 4 oz (115g) semi-sweet chocolate chips
Instructions:
- Preheat the oven to 350°F (175°C). Grease two 8-inch cake pans and line the bottoms with parchment paper.
- In a large bowl, cream the softened butter and granulated sugar together until pale and fluffy.
- Beat in the eggs one at a time, then stir in the vanilla extract.
- Slowly add the flour, baking powder, and salt, alternating with the whole milk, stirring just until combined.
- Gently fold in the coarse Oreo cookie crumbs using a folding technique to avoid over-mixing.
- Divide the batter evenly between the two pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Cool the cakes in the pans for 10 minutes before transferring them to a wire rack to cool completely.
- Prepare the buttercream by beating the butter until creamy, then gradually adding powdered sugar and heavy cream until airy. Fold in the Oreo dust.
- Assemble the cake by layering the sponges with a thick spread of Oreo buttercream.
- Prepare the ganache by heating heavy cream and stirring in semi-sweet chocolate chips until smooth. Drip over the cake and decorate with whole Oreo cookies.
- Chill the cake in the refrigerator for 2 hours to stabilize the frosting before serving.
