How to Make Peanut Butter Marshmallow Cookie Bars

  1. Preheat oven to 350°F (175°C).
  2. Crust: In a large bowl, combine 1 box (15.25 oz) yellow cake mix, 1/2 cup (1 stick) margarine, softened, and 1 large egg.
  3. Mix until the mixture resembles coarse crumbs.
  4. Press the crumb mixture firmly into the bottom of an ungreased 13x9 inch baking pan.
  5. Bake for 15-20 minutes, or until the crust is lightly golden brown.
  6. Remove from oven and immediately sprinkle evenly with 3 cups mini marshmallows.
  7. Return to the oven for 1-2 minutes, or until the marshmallows are lightly puffed.
  8. Topping: In a medium saucepan over medium heat, combine 1/2 cup light corn syrup, 1/4 cup (1/2 stick) margarine, 1 teaspoon vanilla extract, and 1 cup peanut butter chips.
  9. Stir frequently until the chips are melted and the mixture is smooth.
  10. Remove from heat and stir in 3 cups Rice Krispies cereal (or similar crispy cereal).
  11. Immediately spread the peanut butter topping evenly over the marshmallow layer.
  12. Refrigerate for at least 30 minutes to allow the bars to set completely before cutting into squares.
