Contest-Winning Chocolate Potato Cake

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.

  • Makes
    12 servings

Ingredients

  • 1 cup butter, softened
  • 2 cups sugar
  • 2 large eggs, room temperature
  • 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 whole milk
  • 1 cup chopped walnuts or pecans
  • CARAMEL ICING:
  • 1/2 cup butter, cubed
  • 1 cup packed brown sugar
  • 1/4 cup evaporated milk
  • 2 cups confectioners' sugar
  • 1/2 teaspoon vanilla extract

Directions

  • In a large bowl, cream butter and sugar until light and fluffy. Add 1 egg 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.
  • Pour into 2 greased and floured 9-in. round baking pans. Bake at 350° until a toothpick inserted in the center comes out clean, 25-30 minutes. Cool for 10 minutes before removing from pans to wire racks to cool completely.
  • 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.

    This is the exact recipe that my grandmother used to make for all of my birthdays when I was a girl in school. I highly recommend this cake and can't think of any changes that would make it better. FIVE STARS PLUS

    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.
