How to make confetti squares

Spatula stirring melting peanut butter and butter in a stainless steel saucepan.

In a small saucepan, melt the butter and peanut butter together.

Spatula stirring peanut butter and butter melting in a stainless steel saucepan.

Heat only until the mixture is melted and warm. Do not boil.

Spatula stirring thickened melted peanut butter and butterscotch chips in a stainless steel saucepan.

Remove from heat, make sure the peanut butter mix is NOT too hot before adding the butterscotch chips.

Stir continually until the butterscotch chips are melted.

Important TIP: Before adding the butterscotch chips, you want to have the peanut butter and butter mixture warm enough to melt the butterscotch chips, but not so hot that it seizes them up. This will cause the sugars to become grainy and crystallized, instead of the desirable smooth and creamy texture that makes perfect confetti squares. I dip my finger in the peanut butter mixture to test how hot it is.

Spread evenly into a 8×8 buttered baking pan. Refrigerator until set.

Options:

If you prefer a greater fudge ratio, simply reduce the mini marshmallows by a cup. A 10 oz. (250 grams) bag is about 5.5 cups.
I love the fruity flavor of colored marshmallows but they can be substituted with white marshmallows if you like.

Notes

One important tip I have: when making Butterscotch Confetti Squares make sure the butter/peanut butter mix isn’t too hot prior to adding the butterscotch chips. I have done this, and instead of being smooth and creamy it becomes grainy because the sugars crystallize. This will not combine well with the marshmallows.
