Ingredients

  • 3 teaspoons all purpose flour
  • 7/8 cup caster sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 40 grams cocoa powder
  • 2 sticks softened butter
  • 2 large eggs
  • 2 teaspoons vanilla
  • 3/4 cup sour cream
  • 1 1/2 sticks softened butter
  • 3 tablespoons shortening
  • 3 tablespoons blackberry jam
  • 4 cups powdered sugar
  • 1 teaspoon vanilla
  • 1/2 teaspoon salt
  • 4 tablespoons milk

Method

  • Pre-heat the oven to 350° F and grease the cake pan. If you are using normal cake rounds, you will need 2.
  • Mix together the flour, sugar, baking powder, and baking soda.
  • Beat in the butter until creamy. I ended up using 2 sticks of butter because my mixture wasn't creamy with only 1 1/2 sticks.
  • In a separate bowl, whisk together the cocoa, sour cream, vanilla, and eggs.
  • Pour the chocolate mixture into the butter mixture and beat until fully incorporated.
  • Pour into your cake pans, and bake for about 35 minutes. Be sure to turn the pans halfway through the cooking time.
  • The cake is done when a toothpick inserted comes out clean.
