Peanut Butter – Creamy peanut butter will work the best here.
Marshmallows – Mini Marshmallows will work the best. We used these colored mini marshmallows with fruity flavors.
How to make Marshmallow Squares
Melt together the peanut butter, butter, and butterscotch chips before adding vanilla extract.
Add in the marshmallows and quickly fold in with the mixture.
Transfer the mix to a lined and greased baking dish and let set before cutting into squares and serving.
Start things off by setting a non-stick pot over medium-low/low heat. Melt the butter, add the peanut butter, and let those melt together before adding the butterscotch chips.
Stir that occasionally until the chips melt in with the butters. Here, add in a touch of vanilla extract, stir it in, then cut the heat.
After the mix is mostly cooled and melty, we’re going to add in our marshmallows. Toss them in and quickly fold them in with the peanut-butterscotch mix until they’re mixed throughout.
All that’s left is to transfer the mix to a baking dish lined with parchment paper and greased with cooking spray or shortening. This’ll make sure it doesn’t stick to your pan- keep clean up real easy. Transfer to the dish and put in the fridge to set for an hour or two. Once set, remove from the tray, cut into Confetti Squares and enjoy!
