Ingredients:

  • 2 cups (250g) All-purpose flour
  • ¾ cup (150g) Granulated sugar
  • ½ cup (45g) Unsweetened cocoa powder
  • 1 tsp (5g) Baking soda
  • ½ tsp (3g) Salt
  • 1 cup (240ml) Buttermilk, room temperature
  • ½ cup (120ml) Vegetable oil
  • 2 Large eggs, room temperature
  • 1 tsp (5ml) Vanilla extract
  • 1 cup (115g) Finely crushed Oreo cookies
  • 1 cup (225g) Unsalted butter, softened
  • 4 oz (115g) Cream cheese, softened
  • 3 ½ cups (420g) Powdered sugar
  • 1 tsp (5ml) Vanilla extract
  • 2 tbsp (30ml) Heavy cream
  • 8 oz (225g) Oreo cookies, pulsed into fine crumbs

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.
  2. Sift flour, sugar, cocoa, baking soda, and salt into a large mixing bowl.
  3. Whisk in the buttermilk, oil, eggs, and vanilla until the batter is smooth.
  4. Gently fold in the 1 cup of crushed Oreo cookies until evenly distributed.
  5. Divide the batter equally between the two pans. Bake for 28-32 minutes or until a toothpick inserted comes out clean.
  6. Let the cakes rest in the pans for 10 minutes before transferring to a wire rack to cool completely.
  7. Beat the softened butter and cream cheese together using an electric mixer until pale and fluffy (about 3 minutes).
  8. Slowly add powdered sugar one cup at a time on low speed, then increase to medium.
  9. Mix in the vanilla extract and heavy cream until the frosting reaches a spreadable, velvety consistency.
  10. Gently stir in the 8 oz of pulsed Oreo crumbs.
  11. Frost the cooled cake layers and chill for 2 hours before serving.
