Ingredients

  • 1/2 cup butter
  • 1 cup peanut butter
  • 300 g butterscotch chips (1 bag)
  • 4 cups coloured mini marshmallows (1 bag)
  • 1 tsp vanilla extract optional

Instructions

  • Line an 8x8 pan with aluminum foil.
  • Melt butter, peanut butter and butterscotch chips over low heat, stirring until smooth.
  • Remove from heat, and let cool until you can safely hold your hand against the bottom of the pot. This will ensure your marshmallows won't melt when added.

  • Pour mixture into 8x8 pan and gently spread with a spoon or spatula.
  • Refrigerate until firm.
  • Remove from pan and slice into squares.
  • Store squares in refrigerator or wrap in parchment and aluminum foil and freeze.
