This Peanut Butter Marshmallow Squares recipe is an easy, no-bake dessert perfect for any occasion. Made with creamy peanut butter, sweet butterscotch chips, and mini marshmallows, these squares offer a delicious mix of flavors and textures. Ready in just minutes with simple ingredients, they’re a great choice for holiday treats, potlucks, or anytime you need a quick, crowd-pleasing dessert. If you’re looking for a nostalgic, kid-friendly dessert, these peanut butter marshmallow squares are a must-try!

Ingredients:

  • 2 cups butterscotch chips
  • 1 cup smooth peanut butter
  • 4 tbsp unsalted butter
  • ½ tsp vanilla extract
  • Pinch of salt
  • 1 (10 oz) bag mini marshmallows (rainbow or regular)

Instructions:

  1. Prepare the Pan: Lightly spray an 8-inch square baking pan with cooking spray and line it with parchment paper, allowing extra paper to hang over the sides for easy removal.
  2. Melt the Mixture: In a microwave-safe glass bowl, combine the butterscotch chips and peanut butter. Microwave in 20-30 second intervals, stirring in between, until the mixture is fully melted and smooth.
  3. Add Flavoring: Stir in the vanilla extract and a pinch of salt. Allow the mixture to cool to room temperature to prevent melting the marshmallows in the next step.
  4. Add Marshmallows: Once cooled, gently fold in the mini marshmallows until evenly combined.
  5. Chill the Mixture: Pour the marshmallow mixture into the prepared pan, spreading it evenly. Refrigerate for about 2 hours or until set.
  6. Cut and Serve: Once firm, lift the mixture out of the pan using the parchment paper, cut into squares, and serve. Enjoy!

Tips

  • Cooling is Key: Make sure the mixture cools to room temperature before adding marshmallows to keep them intact.
  • Easier Slicing: Let the chilled mixture sit at room temperature for 5-10 minutes before slicing to prevent crumbling.

Variations and Substitutions

  • Add texture: For a bit of crunch, stir in chopped nuts like peanuts or almonds before adding the marshmallows.
  • Try flavored chips: Substitute some of the butterscotch chips with chocolate or white chocolate chips for a different flavor twist.
  • Make it dairy-free: Use dairy-free butterscotch chips and a vegan butter substitute if needed.

FAQs

  • Can I use crunchy peanut butter? Yes, but it will give the squares a more textured bite.
  • How long do they keep? Store these squares in an airtight container in the refrigerator for up to 1 week.

Serving Suggestions

  • Serve chilled: These squares are best served straight from the fridge for the firmest texture.
  • Add to dessert platters: These colorful, sweet treats look great on dessert trays for parties and gatherings.
