Ingredients
  

Base Ingredients
  • 1 cup creamy peanut butter Use a high-quality brand like Jif or Skippy for the best texture.
  • 1 cup granulated sugar Provides the sweetness that makes these bars irresistible.
  • 1 large egg, room temperature At room temperature for better mixing.
  • 1 package mini marshmallows (10 ounces) Provides that chewy, fluffy layer.
  • 1 package butterscotch chips (11 ounces) Use premium brands for the best flavor.
  • 1/4 cup unsalted butter Always unsalted to control saltiness.
  • 2/3 cup light corn syrup Essential for a gooey texture.
  • 1 tablespoon vanilla extract Enhances the overall flavor.
  • 5 cups crispy rice cereal, like Rice Krispies Provides crunchy texture.

Method
 

Preparation
  1. Preheat your oven to 350 degrees F. Line a 9×13-inch baking dish with parchment paper.
  2. In a medium bowl, mix together the creamy peanut butter, granulated sugar, and room temperature egg until well combined and smooth (about 2-3 minutes).
  3. Spread the mixture evenly in the lined baking dish and bake for 14-15 minutes until the edges are lightly golden brown.
  4. Sprinkle the mini marshmallows over the top and return to the oven for an additional 7 minutes until puffy and golden.
Making the Topping
  1. In a large pot over medium heat, melt together butterscotch chips, unsalted butter, light corn syrup, and vanilla extract. Stir until melted and combined (about 3-5 minutes).
  2. Remove from heat and fold in the crispy rice cereal until fully coated.
  3. Spread the cereal mixture evenly over the marshmallow layer and press down gently for even distribution.
Cooling and Serving
  1. Allow the bars to cool for 8-12 hours, or until fully set. Optionally, refrigerate for a quicker set.
  2. Remove the bars from the dish using parchment paper, cut into squares, and enjoy!

Notes

For best results, ensure marshmallows are puffy and golden before removing from the oven. Allowing the bars to cool completely is crucial for clean cuts.
