  • 1 3/4 cups all purpose flour
  • 1/4 cup cornstarch
  • 3/4 cup unsweetened cocoa
  • 3/4 teaspoon baking soda
  • 2 teaspoons baking powder
  • pinch salt
  • 2 cups sugar
  • 2 large eggs
  • 1 cup homemade buttermilk*
  • 1 cup warm water
  • 3 tablespoons vegetable oil (I use corn oil)
  • 1 teaspoon vanilla

*add one tablespoon of white vinegar to a cup of buttermilk and let sit for 5 minutes. Stir to combine before using.


    • 1 1/2 cups whole/ heavy or whipping cream
    • 1 cup mascarpone
    • 1/4 cup Nutella


    • 6 Baci Perugina Chocolates


    • Pre-heat oven to 350F (180C) and grease and flour 2 8 inch cake pans.


    • In a large bowl sift together the flour, corn starch, cocoa, baking soda, baking powder and salt. 
    • Then add the sugar and whisk together, add the eggs, buttermilk, warm water, oil and vanilla beat on medium speed until smooth, approximately 2 minutes.
    • Divide the batter between the two prepared pans and bake for approximately 30-35 minutes or until toothpick comes out clean.  Let cool, then remove from pans.


    • In a medium bowl beat together until very thick the cream and mascarpone.  Fold in the Nutella until streaks form. It only takes a 4 or 5 foldings.


    • Remove the tops of the cakes to form flat layers.  Place one layer on a plate and top with 1/4 of the frosting, place the other layer on top and spread almost all the remaining frosting (leave approximately 1/2 cup to form rosettes on the top to hold the baci chocolates, I used a 1M tip) over the cake, including the sides.  Top with rosettes and Baci chocolates.  Enjoy!
