I've been asked to share this marshmallow chocolate bar recipe more than any other in my collection. It's a longtime favorite of our three daughters. How many times we've all made these, I can't count. — Esther Shank, Harrisonville, Virginia

Ingredients

  • 3/4 cup butter, softened
  • 1-1/2 cups sugar
  • 3 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1-1/3 cups all-purpose flour
  • 3 tablespoons baking cocoa
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt

  • 1 cup peanut butter
  • 3 tablespoons butter
  • 2 cups Rice Krispies

Directions

  1. Preheat oven to 350°. In a bowl, cream butter and sugar until light and fluffy, 5-7 minutes. Add eggs, 1 at a time, beating well after each addition. Beat in vanilla.
    Combine flour, cocoa, baking powder and salt; gradually add to creamed mixture. Stir in nuts if desired. Spread into a greased 15x10x1-in. baking pan.
  2. Bake until set, 15-18 minutes or until set. Sprinkle with marshmallows; bake 2-3 minutes longer or until melted. Place pan on a wire rack. Using a knife dipped in water, spread marshmallows evenly over the top. Cool completely.
  3. For topping, combine chocolate chips, peanut butter and butter in a small saucepan. Cook and stir over low heat until blended. Remove from the heat; stir in Rice Krispies. Immediately spread over bars. Chill until set.
