  • ½ teaspoon salt
  • 1 cup buttermilk (or 1 cup milk + 1 tbsp vinegar)

For the Oreo Frosting:

Instructions

Step 1: Make the Chocolate Cake

  1. Preheat oven to 350°F (175°C). Grease and line two 9-inch cake pans with parchment paper.
  2. In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add buttermilk, vegetable oil, eggs, and vanilla extract. Mix until combined.
  4. Stir in hot coffee until smooth (batter will be thin).
  5. Fold in crushed Oreo pieces.
  6. Divide batter evenly between the cake pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
  7. Let cakes cool for 10 minutes, then transfer to a wire rack to cool completely.

Step 2: Make the Oreo Frosting

  1. In a large bowl, beat butter until creamy.
  2. Gradually add powdered sugar, alternating with heavy cream until smooth.
  3. Stir in vanilla extract and crushed Oreos until fully combined.

Step 3: Assemble the Cake

 

  1. Place one cake layer on a serving plate and spread a generous amount of Oreo frosting over the top.
  2. Place the second cake layer on top and frost the entire cake.
  3. Decorate with whole Oreos around the edges and sprinkle crushed Oreos on top.

Notes

  • For extra Oreo flavor, mix crushed Oreos into the cake batter AND the frosting.
  • Store in an airtight container at room temp for 1 day or refrigerate for up to 5 days.
  • Swap hot coffee for hot water if you prefer a non-coffee version.
