Ingredients

Chocolate Mayo Cake

  • 3 cups all purpose flour
  • ¾ cup white sugar
  • cup cocoa powder
  • 1 ½ cups mayo
  • 1 ½ cups brewed coffee cooled
  • 1 ½ tsp. baking soda
  • 2 ¼ tsp. baking powder
  • ½ tsp. salt
  • 1 ½ tsp. vanilla extract

Minute Fudge Frosting

  • 1 oz. unsweetened baking chocolate chopped
  • 1 cup white sugar
  • cup milk
  • ¼ cup vegetable shortening
  • ¼ tsp. salt
  • 1 tsp. vanilla extract

Instructions

Chocolate Mayo Cake

  • Preheat oven to 350 degrees. Thoroughly grease Bundt pan with non-stick spray.
  • In a large mixing bowl whisk together all the dry ingredients.
  • Add mayo, coffee and vanilla to the dry ingredients and mix until well combined.
  • Pour cake batter into greased Bundt pan. Bake 35-40 minutes until toothpick comes out clean.
  • Let cake cool in pan for 10 minutes, then turn the cake out onto wire rack and cool completely.

Minute Fudge Frosting

  • While the cake is cooling, combine baking chocolate, sugar, milk, shortening and salt in a saucepan. Bring to a boil over medium-high heat, stirring constantly.
  • Boil frosting for one minute, then remove from heat.
  • Add vanilla and mix well. Allow frosting to thicken enough to pour over cake (20-30 minutes). Frosting should pour nicely over cake, but be thick enough where it doesn't all run off.
