These Peanut Butter Marshmallow Squares are a perfect holiday treat filled with a delicious combination of peanut butter, butterscotch, and marshmallows!

I found this recipe for Peanut Butter Marshmallow Squares (also called butterscotch confetti) and had to share it with you. I found two different versions, one recipe I found has coconut and walnuts added.

The recipe I chose to try is just butter, peanut butter, butterscotch chips, and marshmallows. These are often called church windows!. Whatever you decide to call them I know you’ll want to make them over and over!

How to make Peanut Butter Butterscotch Confetti Squares:

  • FunMallows: These are the Easter colored marshmallows. They are fruity flavored.
  • Butter: I use salted butter
  • Peanut Butter: Creamy peanut butter is best for this recipe.
  • Butterscotch chips: These make the recipe taste unique and add sweetness.
Ingredients for marshmallow squares on a table
  • Line an 8×8 pan with wax paper. Set aside.
  • Melt the butter, butterscotch chips and peanut butter in a pan set to medium-high heat.
  • Cool for 45 minutes before adding the marshmallows. This part is very important, you do not want the marshmallows to melt and disappear into the peanut butter mixture.
  • Add the marshmallows after the mixture has cooled.

  • Pour into the prepared pan.
  • Let cool in fridge for at least 2 hours.
  • Cut into squares. You can make them big or small. I did large squares for my party.

How do I store peanut butter marshmallow squares?

  • Place in airtight containers or ziplock bags.
  • I store mine in the fridge so they will last longer. They keep well for a week.

Can I use regular marshmallows?

Yes! use the same amount of regular marshmallows if you desire or can’t find Funmallows.

Can I use chocolate chips instead of butterscotch chips?

Yes! use semi-sweet chips in place of the butterscotch for a different flavor.

My other favorite holiday desserts:

  • Butterfinger Cookies – You won’t be able to stop eating these.
  • Soda Cracker Toffee– A fun an unique candy recipe.

Can I make these in a muffin tin pan?

  • Yes, line a muffin tin pan with cupcake liners.
  • Scoop the marshmallow mixture into each liner about 1/2 full or 3/4 full (however size you want each serving to be).
  • Refrigerate and serve!

These Peanut Butter Marshmallow Squares smell like Christmas while heating up! These are very similar to fudge and very festive for Easter! I will be making these again. Have a great weekend.

    I made this same recipe, substituted Nutella for peanut butter and used chocolate chips. Added walnuts and cherries.

    What can you use instead of peanut butter? Peanut allergy.

      I’ve never made them with anything else other than peanut butter. If you don’t have other nut allergies, you could try almond or cashew butter, even nutella. If you do, perhaps sunflower butter.

    Me too, after reading the instructions here, I think I didn’t let the peanut butter butterscotch mixture cool long enough

    I place the pot of melted items in the sink in cold water to cool it down faster. When it’s cool to the touch on the bottom of the pot, I know it’s ready.

    Have been making these for about 45 years. Family love them. We like crunchy peanut butter and 1/2 c Rice Krispies to add some crunch. Also prefer to melt butter and peanut butter, cool slightly and then mix in chips. Stir to melt. Mixture Dan be grainy if butter too hot when the chips are added.
    I’m now using sun butter as we have a severe peanut allergy in the family. Delicious.

    These are my absolute favourite. My family devours them. Not sure why you would call this garbage. There is nothing garbage about it. Colourful on the plate.

    I have used this recipe many times and they always turn out great, the only time it varied was when I used unsalted butter?…. Great easy recipe, just remember to let your peanut, butter,chip mixture cool to room temp 70-90 degrees is best. :). Thank you

    I’m not sure what I did wrong, my peanut butter mix doesn’t look watery like yours. Any advice?

      Did you add the butter? That should make it the right consistency.

      Mine too! I think I should have taken it right off as soon as I added the chips . Mix off the heat and let cool a bit . I couldn’t get the marshmallows to fold into the chips mixture.
