Ingredients

  • 1/2 cup butter, softened
  • 1-1/2 cups sugar
  • 2 large eggs, room temperature
  • 1-1/2 cups mashed ripe bananas (about 3 large)
  • 1 cup sour cream
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 2 jars (10 ounces each) maraschino cherries, drained and chopped
  • 2 cups semisweet chocolate chips
  • 1 package (10 ounces) miniature marshmallows
  • Optional: Chopped salted peanuts and banana slices or dried banana chips

Directions

  1. Preheat oven to 375°. Grease a 15x10x1-in. baking pan.
  2. In a large bowl, beat butter and sugar until crumbly, about 2 minutes. Add eggs; mix well. Beat in bananas, sour cream and vanilla. In another bowl, whisk flour, baking soda and salt; gradually add to butter mixture. Transfer to prepared pan.
  3. Bake until a toothpick inserted in center comes out clean, 18-20 minutes. Top cake with cherries, chocolate chips, marshmallows and, if desired, peanuts. Bake until chips are slightly melted and marshmallows puff, 3-5 minutes longer. Cool completely in pan on a wire rack; cut into bars. If desired, top with banana slices or banana chips before serving.
Test Kitchen Tip
  • These bars are chock-full of amazing toppings making them a bit tricky to cut neatly. Plan to eat them with a fork to scoop up all the goodness that falls off.
