Instructions

  1. Step 1: Preheat oven to 350°F. Grease and flour four 8-inch round cake pans.
  2. Step 2: In a large bowl, sift together 2 1/2 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 1/2 tsp baking soda, 1 1/2 tsp baking powder, and 1 tsp salt.
  3. Step 3: In a separate bowl, whisk 2 1/4 cups granulated sugar, 3 large eggs, 1 1/4 cups buttermilk, 1 cup vegetable oil, and 2 tsp vanilla extract until combined.
  4. Step 4: Gradually add the dry ingredients into the wet ingredients, mixing until smooth.
  5. Step 5: Stir in 1 cup boiling water carefully; batter will be thin.
  6. Step 6: Divide batter evenly among the four pans and bake for 25-30 minutes until a toothpick inserted in the center comes out clean.
  7. Step 7: Cool cakes in pans for 10 minutes, then remove to wire racks to cool completely.
  8. Step 8: For frosting, beat 1 cup softened unsalted butter until creamy. Gradually add 4 cups sifted powdered sugar and 1 tbsp vanilla bean paste, alternating with 2-3 tbsp heavy cream, until fluffy and spreadable.
  9. Step 9: Assemble cake by layering each chocolate cake round with a generous spread of vanilla bean frosting in between, frosting the top and sides smoothly.
  10. Step 10: Chill for 30 minutes before slicing to set the layers.
