Liquid and Flavoring Ingredients:

  • ½ cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water
  • 1 cup heavy cream
  • ½ cup cold water

Instructions

  1. Prepare your workspace by heating the oven to 350°F and coating two 9-inch round cake pans with cooking spray.
  2. Combine 2 cups flour, 2 cups sugar, ¾ cup cocoa powder, 2 tsp baking soda, 1 tsp baking powder, and 1 tsp salt in a large bowl.
  3. Whisk 2 eggs, 1 cup milk, ½ cup vegetable oil, and 2 tsp vanilla extract in a separate container until thoroughly blended.
  4. Merge wet and dry ingredients, stirring carefully until just combined.
  5. Gradually pour 1 cup boiling water into the batter, mixing until silky smooth.
  6. Distribute batter equally between prepared cake pans.
  7. Bake for 32-35 minutes, checking with a toothpick for complete doneness.
  8. Allow cakes to rest in pans for 10 minutes after removing from oven.
  9. Transfer cake layers to a wire rack for complete cooling.
  10. Create chocolate pudding by melting 12 oz chocolate chips and 1 cup heavy cream over low heat.
  11. Whisk ¼ cup cornstarch with ½ cup cold water until completely smooth.
  12. Incorporate cornstarch mixture into melted chocolate, cooking for 3-4 minutes until thickened.
  13. Remove pudding from heat and let cool completely.
  14. Prepare buttercream by blending ½ cup butter with 1 cup powdered sugar until fluffy.
  15. Crumble one cake layer and mix with a portion of chocolate pudding.
  16. Layer remaining pudding between cake rounds.
  17. Cover entire cake with buttercream frosting.
  18. Press reserved cake crumbs along cake sides for texture.
  19. Refrigerate cake for minimum 1 hour before serving to set layers.

Notes

  • The boiling water helps create an incredibly moist cake texture, so don’t skip this crucial step.
  • Ensure all ingredients are at room temperature for smoother mixing and better cake consistency.
  • Cooling the chocolate pudding completely prevents it from melting when assembling the cake layers.
  • When crumbling a cake layer, aim for fine, even crumbs to create a smooth exterior coating.
