  • 3 teaspoons vanilla extract divided
  • 1 cup brown sugar firmly packed
  • 1/2 cup sugar
  • 2 ounces chocolate (semi-sweet) or chocolate chips, melted
  • 2 cups flour, all-purpose
  • 113 cups cocoa powder unsweetened, divided
  • 1 tablespoon baking soda
  • 1/2 teaspoon salt

  • 1 1/4 cups sour cream divided
  • 1/2 cup butter softened
  • 3 cups powdered sugar

Method

  • Preheat the oven to 350F (180C).
  • Grease and flour two 8-inch baking pans with butter and flour, set aside.
  • Add vegetable oil, egg, and 2 teaspoons vanilla extract in a large bowl with an electric mixer.
  • Beat at medium speed until well blended, about 1 to 1 1/2 minutes.
  • Beat in both brown sugar and sugar, scraping bowl as necessary, until well blended, another 1 minute.
  • Beat in the melted chocolate, scraping bowl once a while, until well blended, 1 minute or more.
  • Sift together flour, 23 cup unsweetened cocoa powder, baking soda, and salt in a medium bowl.
  • Transfer the flour mixture into chocolate mixture alternately with warm water or milk, beating well after each addition.
  • Beat in 1 cup sour cream until well blended.
  • Pour into prepared cake pans and bake until a wooden stick inserted in the center comes out clean, about 35 minutes.
  • Transfer cakes onto the wire rack and let cool in the pan for about 10 to 15 minutes.
  • Remove the cakes from the pans and allow to cool on the wire rack completely.
  • To make the chocolate sour cream frosting:
  • As the cake is cooling, meanwhile place 1/2 cup softened butter in a large bowl with electric mixer.
  • Beat at high speed until creamy and fluffy, about 2 minutes.
  • Beat in remaining 23 cup cocoa powder and 1 teaspoon vanilla, scraping bowl as needed, until mixture becomes creamy and smooth, about 3 minutes.
  • Beat in the powdered sugar, 1 cup at a time, beating well after each addition.
  • Pour in the milk and 1/4 cup sour cream, keep beating, scraping bowl as necessary, until creamy and smooth, about 2 minutes.
  • Arrange one cake, flat side up, on the bottom of a serving plate.
  • Put about 1 cup frosting in the center of the cake.
  • Spread evenly to about 1/2-inch from the edge of the cake.
  • Set the second cake carefully, flat side up, on top of the frosted first layer.
  • Frost the remaining frosting on sides and top of cake.
  • Garnish if needed, you can add some fresh berries on top, or any your favorite fruits; or you can use some Easter candies to decorate the cake into a Easter chocolate cake; or using some pastry bags to give some nice dots around the edges or in the center.
  • Be creative, of course jut eat it directly without any decoration, it's already delicious enough to satisfy your sweet tooth :)
