Contest-Winning Chocolate Potato Cake Recipe

Contest-Winning Chocolate Potato Cake Recipe

I won grand champion honors in a potato festival baking contest with this moist chocolate cake. The icing recipe can be doubled for real sweet tooths. A great-grandma, I've spent over 85 years on the farm.
TOTAL TIME: Prep: 40 min. Bake: 25 min. + cooling YIELD:10-12 servings


  • 1 cup butter, softened
  • 2 cups sugar
  • 2 eggs
  • 1 cup cold mashed potatoes (without added milk and butter)
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1/2 cup baking cocoa
  • 1 teaspoon baking soda
  • 1 cup milk
  • 1 cup chopped walnuts or pecans
  • 1/2 cup butter, cubed
  • 1 cup packed brown sugar
  • 1/4 cup evaporated milk
  • 2 cups confectioners' sugar
  • 1/2 teaspoon vanilla extract


  • 1. In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Add potatoes and vanilla. Combine the flour, cocoa and baking soda; gradually add to creamed mixture alternately with milk, beating well after each addition. Stir in nuts.
  • 2. Pour into two greased and floured 9-in. round baking pans. Bake at 350° for 25-30 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
  • 3. For icing, in a saucepan over low heat, cook butter and brown sugar until butter is melted and mixture is smooth. Stir in evaporated milk; bring to a boil, stirring constantly. Remove from the heat; cool to room temperature. Stir in confectioners' sugar and vanilla until smooth. Spread between layers and over top of cake. Yield: 10-12 servings.

"Best homemade chocolate cake ever! My picky little siblings adored it (I did not tell them about the potato)! I used raw sugar instead of regular sugar, and rice milk instead of regular milk. Turned out great."
