Description

This sophisticated Cookies and Cream Cake features a moist, oil-based chocolate sponge balanced by a velvety Oreo-infused buttercream. By combining technical baking principles with classic flavors, this dessert delivers a perfect interplay of crunchy textures and a melt-in-the-mouth crumb.


Ingredients

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 cup buttermilk, room temperature
  • 1/2 cup vegetable oil
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup hot brewed coffee
  • 1.5 cups unsalted butter, softened
  • 4-5 cups confectioners’ sugar
  • 1/2 cup finely crushed Oreo cookies
  • 1 cup coarsely chopped Oreo cookies
  • 3 tablespoons milk


Instructions

  1. Preheat your oven to 350°F (175°C) and grease two 8-inch round cake pans or line them with parchment paper.
  2. Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into a large mixing bowl to ensure an even distribution of leavening agents.
  3. In a separate bowl, whisk together the room-temperature buttermilk, oil, eggs, and vanilla until the mixture is homogeneous.
  4. Set the mixer to low speed and slowly combine the wet ingredients with the dry mixture until partially combined.
  5. Pour in the hot coffee and mix only until the flour streaks disappear, being careful not to overwork the gluten.
  6. Divide the batter equally between the prepared pans and bake for 30 to 40 minutes, or until a tester comes out with a few moist crumbs.
  7. Cool the cakes in their pans for 30 minutes to set the structure before turning them out onto a wire rack to cool completely.
  8. Beat the softened butter until aerated, then gradually add confectioners’ sugar, fine Oreo crumbs, and milk until reaching a spreadable consistency.
  9. Level the cooled cakes with a serrated knife, then stack with a layer of buttercream and a scattering of coarse Oreo chunks.
  10. Coat the exterior with the remaining buttercream and garnish with additional cookie pieces before serving.

Notes

For the most professional finish, ensure your butter is exactly room temperature to prevent a greasy frosting consistency. Using a kitchen scale to divide the batter will guarantee even layers, while chilling the cake for 20 minutes after assembly can help set the structure for perfectly clean slices.
