The Secret of Great Cooks

Duke's Chocolate Cake


  • Cake
  • 6 Tbsp. unsweetened cocoa
  • 3 cups all purpose flour
  • 1 Tbsp. baking soda
  • ¼ tsp. salt
  • 1½ cups sugar
  • 1½ cups Duke's Mayonnaise
  • 1½ tsp. Sauer's Vanilla Extract
  • 1½ cups cold water

  • Chocolate Icing
  • 1 cup butter, softened
  • 1 cup cocoa
  • 1 tsp. vanilla extract
  • 5 to 6 cups confectioner's sugar
  • 6 or more tablespoons milk


Preheat oven to 350°F, grease and flour two 8" cake pans. Sift cocoa, flour, baking soda, salt and sugar into a medium bowl, mix well. Combine mayonnaise, vanilla and water in an electric mixer at low speed. Once smooth, slowly add in dry mixture until just incorporated (do not over beat). Pour batter into cake pans and bake for 30 minutes or until done. Cool on wire racks and frost with your favorite chocolate frosting. For the frosting, in the bowl of an electric mixer, beat butter and cocoa with whisk attachment until smooth. Add vanilla. Add confectioner's sugar alternately with milk until icing reaches a spreadable consistency. Note: you may not need all 6 cups of sugar; you may need more than 6 tablespoons of milk.
