Banana Bars with Cream Cheese Frosting

I make this moist recipe for banana bars made with sour cream whenever I have ripe bananas on hand, then store them in the freezer to share later at a potluck. With creamy frosting and big banana flavor, this treat is a real crowd-pleaser. —Debbie Knight, Marion, Iowa

Ingredients

  • 1/2 cup butter, softened
  • 1-1/2 cups sugar
  • 2 large eggs, room temperature
  • 1 cup sour cream
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 medium ripe bananas, mashed (about 1 cup)
  • FROSTING:
  • 1 package (8 ounces) cream cheese, softened
  • 1/2 cup butter, softened
  • 2 teaspoons vanilla extract
  • 3-3/4 to 4 cups confectioners' sugar

Directions

  • Preheat oven to 350°. In a large bowl, cream butter and sugar until light and fluffy. Add eggs, sour cream and vanilla. Combine flour, baking soda and salt; gradually add to creamed mixture. Stir in bananas.
  • Spread into a greased 15x10x1-in. baking pan. Bake 20-25 minutes or until a toothpick inserted in the center comes out clean (do not overbake). Cool.
  • For frosting, in a large bowl, beat cream cheese, butter and vanilla until fluffy. Gradually beat in enough confectioners' sugar to achieve desired consistency. Frost bars. Store in the refrigerator.

Test Kitchen Tips
  • For the most intense flavor, use bananas with plenty of brown spots on them. Great way to use up leftovers in your fruit bowl!
  • Get crunchy by adding toasted walnuts or black walnuts to the batter, or sprinkling them over the frosting.
  • These 76 dessert bars are perfect for parties.

      So good. I know I'm leaving this rating awfully late, but I made this up as a dessert for Christmas. And there was none left at the end of the day. So good!

      Easy and delicious! Did not get 4 dozen from this recipe - maybe my family likes big servings!

      I made this as written-came out perfectly! I made the bars for a church gathering, and they were a big hit. It definitely made enough to feed a crowd. The cake is moist and delicious, and the frosting scrumptious! I kept them well chilled and they were a yummy treat. VFE

      This was super easy to make and the results were a delicious and moist cake! I substituted Greek yogurt for sour cream because it was what I had on hand. I also frosted it with a maple brown butter frosting. Delicious!

      This recipe is wonderful. Very moist, huge banana taste and the best cream cheese icing I’ve ever made. A keeper for sure. As mentioned they freeze well and take no time to thaw when you’re ready for dessert. I put the bars in the refrigerator after I ice them so they are easier to cut with icing on them.

      This is a great recipe and everyone really enjoyed them. I did have to bake the bars an additional 15 minutes. The only change I made was reducing the vanilla extract,in the frosting, by 1/2 tsp and adding 1/2 tsp. of banana extract.
