About This Recipe

This is the perfect simple marshmallow recipe to make with the whole family, since you can do all of the cooking in a saucepan on low heat yourself so no one burns themselves. I usually leave my kids in charge of the chocolate chips, which means that a lot of them never make it into the pan, which is a risk I just have to take.

Chef’s Notes

Peanut Butter Chocolate Marshmallow bars are best served straight from the fridge, since cooling them makes them firm and brings out all the flavors. Honestly, the most difficult part about making this easy recipe is waiting for the squares to harden in the fridge. These are great to serve up at a holiday party or potluck, since this is a gluten free recipe that many can enjoy.

How to Store

  • Serve: You can store Chocolate Marshmallow Peanut Butter Squares at room temperature for up to 2 days. Always keep them in an airtight container or sealable bag. I recommend keeping them on a sheet of parchment paper.
  • Store: You can store the squares in the fridge in an airtight container for up to 4 days.
  • Freeze: You can also freeze the recipe for up to 4 months.

Frequently Asked Questions

How do you melt marshmallows?

You can use a saucepan to melt them, or you can put them in a microwave-safe bowl and microwave them. Make sure to stir to keep them from burning or fusing to the bowl.

Is microwaving marshmallows safe?

Yes, but I think you get a better texture and taste by melting them in a saucepan instead. Plus the clean up is easier, marshmallows can get really messy in a microwave.

Variations

  • Add ins: Add in a handful or two of sliced or chopped nuts like cashews, pecans, or walnuts. You can also add some pretzel bits, Chex or Rice Krispies cereal in to the mix for a salty sweet combination.
  • Chips: You can switch things up a bit by changing the flavors of the chocolate chips you add. Try white chocolate, peanut butter chips, milk chocolate chips, or dark chocolate chips.
  • Marshmallows: If you want to make the whole recipe from scratch, you can use my recipe for Homemade Marshmallows. You can shape these into whatever size you want, and I’ve occasionally used a mini cookie cutter on them to make them into cute Christmas shapes.

  1. When do you transfer to the 8 x 8 pan? After melting in Dutch oven? Before letting it sit 10 minutes? This sounds delicious.

    1. Glad you asked! After the batter is cooled you add marshmallows and chocolate chips, mix and then transfer to the 8×8 inch baking dish lined with parchment paper. Then add the rest of the remaining marshmallows and chocolate chips to the top of the batter, pressing into the batter. Then refrigerate. Appreciate you bringing this to our attention!
