Ingredients

Scale

Ingredients

  • ½ cup (1 stick / 113 g) unsalted butter
  • 2 cups (340 g) butterscotch chips
  • ¾ cup (190 g) creamy peanut butter
  • 4 cups (200 g) miniature marshmallows

Instructions

  1. Prepare the Pan: Line an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later, and set aside.
  2. Melt Ingredients: In a large microwave-safe bowl, combine the butter, butterscotch chips, and creamy peanut butter. Microwave the mixture in 30-second intervals, stirring after each interval, until the mixture is smooth and fully melted. This should take about 1 to 1½ minutes total.
  3. Cool the Mixture: Allow the melted mixture to sit at room temperature for 10 to 15 minutes. This step is essential to prevent the marshmallows from melting prematurely when added.
  4. Incorporate Marshmallows: Gently fold in the miniature marshmallows, making sure they are completely coated with the butterscotch and peanut butter mixture.
  5. Transfer and Chill: Pour the mixture into the prepared pan and press down evenly with a spatula. Refrigerate for at least 2 hours or until firm and fully set.
  6. Serve: Using the parchment paper overhang, lift the bars out of the pan and cut into squares. Serve chilled for the best texture and flavor.

Notes

  • Make sure to let the melted mixture cool before adding marshmallows to avoid melting them.
  • Use parchment paper for easy removal and clean cuts.
  • Store bars in an airtight container in the refrigerator to maintain freshness.
  • For a nut-free version, omit the peanut butter and consider using sunflower seed butter.
