These easy Peanut Butter Marshmallow Bars are a classic Canadian no-bake Christmas treat. Known also as Confetti Slice and miriad of other names, you can make them the classic way, or add Rice Krispies for crunch and texture.
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.
Stir in vanilla (if using), marshmallows and Rice Krispies.
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.
Notes
For smaller squares, cut pan into 5 rows of 5. For larger squares, cut into 4 rows of 4.
