I found this recipe more than five years ago and have been making it for family gatherings ever since. The coffee-flavored frosting complements the moist banana cake. —Kathy Hoffman, Topton, Pennsylvania

  1. In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla. Combine the flour, baking soda and salt; add to creamed mixture alternately with bananas and sour cream, beating well after each addition.
  2. Pour into a greased 13x9-in. baking dish. Bake at 350° for 35-40 minutes or until a toothpick inserted near the center comes out clean. Cool completely on a wire rack.
  3. For frosting, in a small bowl, beat butter and confectioners' sugar until smooth. Dissolve coffee granules in milk; add to butter mixture and beat until smooth. Spread over cake. Yield: 12-15 servings.

Test Kitchen Tips
  • Very ripe bananas work best in this cake.
  • Bananas can vary widely in size. To prevent your cake from becoming too dry, use a cup measure for mashed banana. For 1-1/2 cups mashed, plan on three medium bananas.
  • If you don't happen to have instant coffee for the frosting, strong brewed regular coffee or espresso would work, too. Be sure to adjust the milk amount to compensate for the added liquid.

    "I use cream cheese frosting on this cake. Very good! A burnt sugar frosting works well also. I bake in jelly roll pan for approximately 20 minutes."

    "This cake was really easy to put together and was a hit with everyone. We really liked the frosting. I did use brewed espresso instead of instant coffee granules. It's a great way to use up bananas that are starting to brown. One of my children isn't a fan of bananas, but said this cake was good."

    "This dessert is a GAME CHANGER for any potluck, office party, family event, holiday, or any day of the week. Delicious! The frosting is good, but sometimes I just opt for a Nutella spread on top if I'm too lazy to make my own. This recipe is definitely a keeper!"

    "The only thing I'd change would be to use 2-3 tablespoons of fresh brewed strong coffee instead of instant. The coffee flavor is more than just a hint, so prepare for coffee lovers! I also think that a cream cheese frosting base with coffee flavor would be excellent . I want to try that next time I make this."

    "There was no liquid in this recipe and it was flat, gummy and more like a cookie after it cooked. I will never try this again. Probably needed a cup of water or milk."
