This favorite recipe has been passed down through my husband’s family. His grandmother wrote this out for me shortly after we were married. She copied it from a recipe that her mother had written out for her many years before. These handwritten treasures in my recipe box bring back so many fond memories. —Jamie Dunn, Milwaukee, Wisconsin

  • 1-1/2 cups sugar
  • 1/2 cup shortening
  • 2 eggs
  • 1 teaspoon vanilla
  • 1/2 cup buttermilk
  • 3 mashed bananas
  • 2 cups flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup butter, softened
  • 2-1/2 cups powdered sugar
  • 3 tablespoons milk
  • 1 teaspoon vanilla
  • Dash of salt


  1. Cream sugar and shortening together; add eggs and vanilla. Mix in buttermilk and mashed bananas.
  2. In a separate bowl, combine flour, soda, baking powder and salt; add to banana mixture and mix until ingredients are combined. Spoon into a greased 13x9-in. baking pan or two 9-in. round cake pans.
  3. Bake at 350° for 25-30 minutes or until toothpick inserted into center comes out clean. Cool cake for 30 minutes before frosting.
  4. For frosting, mix butter, powdered sugar and milk until smooth; add vanilla and salt. If frosting is too thick, add more milk 1 tsp. at a time until reaching desired consistency. Spread on warm banana cake.
Homemade buttermilk
For each cup of buttermilk, you can use 1 tablespoon of white vinegar or lemon juice plus enough milk to measure 1 cup. Stir, then let stand for 5 minutes. You can also use 1 cup of plain yogurt or 1-3/4 teaspoons cream of tartar plus 1 cup milk.
