Equipment

  • 1 9x13 casserole dish

Ingredients

  • ¼ cup unsalted butter
  • 10 ounces. bag mini marshmallows
  • 1 cup peanut butter divided use
  • 6 cups Rice Krispies cereal
  • 8 ounces semi-sweet chocolate chips
  • 8 ounces vanilla icing
  • ¼ teaspoon green gel food coloring
  • candy sprinkles

Instructions

  • Generously grease a 13x9” baking dish with cooking spray, set aside.
  • In a large saucepan over low heat, melt the butter, mini marshmallows and ½ cup peanut butter together. Once melted, add the Rice Krispies, and stir well to evenly coat the cereal.

  • Transfer the mixture to the prepared baking dish, and FIRMLY press the mixture into the bottom of the pan. Set aside.

  • In a medium microwave-safe bowl, add the chocolate chips and remaining ½ cup peanut butter. Microwave at 30-second intervals until the chocolate is melted, and the mixture is smooth.

  • Pour the chocolate peanut butter mixture over the pressed Rice Krispies in the baking dish, and spread evenly using a spatula. Give the pan a little shake to further smooth the chocolate topping.

  • Place the baking dish in the refrigerator for an hour (or in the freezer for 30 minutes) to allow the dessert to harden and set.
  • Once set, remove the treats from the dish- in one whole piece. (It may be helpful to run a thin knife along the outer edge of the dessert to help it out.) Using a knife, cut the entire dessert in half, lengthways, then cut each half into triangles.

  • Add the icing and gel food coloring to a small bowl, and mix well until there no more streaks. Transfer the icing to a piping bag that has been fitted with a tip. (Alternatively, you could transfer the icing to a plastic baggie, and cut a tiny piece of the corner from the bag.) Decorate. Pipe zigzag lines onto the triangles with the green icing creating trees, and garnish with sprinkles. Enjoy!
