Ingredients

  • 3/4 cup unsweetened cocoa powder
  • 1 3/4 cups all-purpose flour
  • 1 1/2 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 3/4 cups granulated sugar
  • 1/2 cup unsalted butter, softened
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup whole milk
  • 1 cup boiling water
  • For the pudding filling:
  • 1/2 cup granulated sugar
  • 1/4 cup cornstarch
  • 1/4 tsp salt
  • 2 1/2 cups whole milk
  • 6 oz bittersweet or semi-sweet chocolate, chopped
  • 1 tsp vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a bowl, sift together flour, cocoa powder, baking powder, baking soda, and salt.
  3. In a large mixing bowl, cream butter and sugar until light and fluffy.
  4. Add eggs one at a time, beating well after each. Stir in vanilla extract.
  5. Alternate adding dry ingredients and milk to the creamed mixture. Stir in boiling water last — batter will be thin.
  6. Divide batter between pans and bake for 30–35 minutes, or until a toothpick comes out clean. Cool completely.
  7. For pudding: In a saucepan, whisk sugar, cornstarch, salt, and milk over medium heat until thickened and bubbling.
  8. Remove from heat and stir in chocolate until smooth. Add vanilla. Let cool completely, covered with plastic wrap touching the surface.
  9. Once cakes are cool, slice each in half to make 4 layers. Reserve one layer to crumble for topping.
  10. Spread pudding between layers and over top and sides of the cake. Gently press reserved cake crumbs onto frosting.
  11. Refrigerate for 2–3 hours to set before slicing.

Notes

  • Let the pudding cool completely before using it to prevent cake from becoming soggy.
  • Use a serrated knife to level cake layers evenly.
  • Chill cake before serving for best texture and clean slices.
  • Use high-quality chocolate for the best pudding flavor.
