How do you make peanut butter confetti squares?

To make the perfect Peanut Butter Confetti Squares: Melt peanut butter and butter in saucepan on LOW heat, just until melted. Then add the butterscotch chips on LOW heat until they melt and you have a combined mixture.

Remove the mixture from heat entirely, and allow to cool to room temperature. This will take about 10-15 minutes, but necessary so the marshmallows don’t melt when added.

Next you fold in the marshmallows until combined and press into a 8×8 greased baking pan. Refrigerate until firm and cut into squares – it’s just that easy.

Can you freeze confetti squares?

I also love that you absolutely CAN freeze confetti squares, and I have some in my freezer right at this moment in tins for myself and for friends. To freeze, layer the squares in between parchment paper so they don’t stick together.

When taking out of the freezer, they thaw fast too. This means you can take them out when company arrives and always have a holiday dessert to offer.

Or, take one out to enjoy when your sweet tooth craves.
