Preparation

Preheat oven to 375°. Grease a 15x10x1-in. baking pan.

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.

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.
