  • 4 large Eggs
  • 1 cup Whole Milk
  • 1/2 cup Vegetable Oil
  • 2 teaspoons Vanilla Extract
  • 1 cup Boiling Water

For the Frosting

  • 4 cups Powdered Sugar
  • 1/4 cup Heavy Cream
  • 2 teaspoons Vanilla Extract
  • 1 cup Crushed Oreo Cookies

Garnish

  • 12 pieces Whole Oreo Cookies

Instructions
 

Preparation

  • Preheat your oven to 350°F (180°C) and grease two 9-inch round cake pans.
  • In a large bowl, combine the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  • Beat in the eggs, milk, vegetable oil, and vanilla extract until smooth.
  • Stir in the boiling water until well mixed; the batter will be thin.
  • Pour the batter evenly into the prepared cake pans.

Baking

  • Bake for 30-35 minutes or until a toothpick comes out clean.
  • Allow cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.

Making the Frosting

  • While cooling, make the frosting by beating the softened butter until creamy.
  • Gradually add powdered sugar, heavy cream, and vanilla, mixing until fluffy.
  • Fold in the crushed Oreo cookies.

Assembly

  • Place one cake layer on a serving plate and spread frosting on top.
  • Add the second layer and frost the top and sides of the cake.
  • Garnish with whole Oreos and drizzle with chocolate ganache if desired.

Notes

Add a sprinkle of sea salt on top for an enhanced flavor contrast. Customize by swapping in other crushed cookies or candies, serve with fresh berries for a touch of freshness.
