Ingredients
  

For the Cake:

  • 1 ¾ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 ½ tsp baking powder
  • 1 ½ tsp baking soda
  • ½ tsp salt
  • 2 cups granulated sugar
  • 2 large eggs
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 1 tsp vanilla extract
  • 1 cup hot water or hot coffee to intensify the chocolate flavor
  • 10 –12 Oreo cookies roughly chopped

For the Frosting:

  • 1 cup 2 sticks unsalted butter, softened
  • 4 cups powdered sugar
  • ¼ cup heavy cream or milk
  • 1 tsp vanilla extract
  • Pinch of salt
  • 10 –12 Oreo cookies finely crushed (plus extras for garnish)

Instructions
 

  • Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment.
  • In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  • In another bowl, beat sugar, eggs, buttermilk, oil, and vanilla until smooth. Gradually add dry ingredients.
  • Slowly mix in hot water or coffee (batter will be thin). Fold in chopped Oreos.
  • Divide batter evenly between pans and bake for 28–32 minutes, or until a toothpick comes out clean.
  • Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.

Make the Frosting:

  • Beat butter until fluffy. Add powdered sugar, one cup at a time, mixing well. Add cream, vanilla, and salt; beat until smooth and creamy. Fold in crushed Oreos.

Assemble the Cake:

  • Spread frosting between layers and on top and sides of cake. Decorate with extra Oreo cookies or crumbs.

Notes

  • For a more intense chocolate flavor, use hot coffee instead of water.
  • Chill the cake before slicing for cleaner layers.
  • Can be made as a sheet cake or cupcakes (adjust baking time).
  • Store in the fridge for up to 5 days; let come to room temp before serving.
  • Want to make it extra? Add a chocolate ganache drizzle on top!
