There are so many different desserts you can make with marshmallows, like Marshmallow Crunch Brownie Bars, and Peanut Butter Confetti Squares are one of the easiest you’ll ever try. A perfect sweet treat for bake sales and potlucks.

Sabrina’s Peanut Butter Confetti Squares Recipe

Marshmallow, peanut butter and butterscotch confetti squares are a yummy treat that comes from an easy recipe and can sit out at room temperature for long periods of time, which makes them great for the next bake sale you forget about until the last minute. The recipe is great if you want to let an aspiring chef try cooking for the first time with supervision, because it’s quick, easy and doesn’t need a ton of clean up. If you want to be really impressive, make your own Homemade Marshmallows from scratch first. For a little more sweetness, try the Chocolate Confetti Squares or make both to mix on a dessert platter!

Chef’s Note: Freezing Tips and Tricks

Here’s a tip to get your frozen confetti squares out of the pan easier: line the bottom with wax paper or parchment paper first, making sure to leave enough poking up over the top to get a good grip on. Once the confetti squares have set, evenly pull up the paper and your dessert will come out with it.

How to Store

  • Serve: you can leave peanut butter marshmallow squares at room temperature for a pretty long time, but they taste a lot better chilled so I wouldn’t leave them out for longer than about 2 hours.
  • Store: you can keep confetti squares in the fridge for about a week before they start to go bad.
  • Freeze: the squares won’t freeze all the way through, so freezing them doesn’t extend their shelf life very much. But, if you want a thicker texture, pop them in the freezer for a few days and eat them directly after taking them out.

Variations

  • Mini Marshmallows: if you want a different look and texture, use mini marshmallows. Just be aware that you will have to use more of them than you would expect.
  • Chocolate Chips: add chocolate chips when you stir in the marshmallows. If that’s just not going to satisfy your sweet tooth, you can also use chunks of fudge.
  • Cupcakes: follow the recipe the same way but separate the marshmallow bars into a muffin tin instead of a single pan to make perfect, shareable treats for a party.
  • Nuts: if you use crunchy instead of creamy peanut butter, your confetti squares will feel like you stirred in hand chopped nuts without you having to add the extra step.

  4. In the ‘How to Make Peanut Butter Confetti Squares’ section it mentions adding salt, but there is no salt listed in the ingredients. How much salt should be added? I usually use unsalted butter and natural peanut butter so will need to add salt for these to taste proper. Thank you!
