This old-fashioned Confetti Squares recipe an easy, no-bake treat with peanut butter, butterscotch and marshmallows. It’s a Canadian classic!
Let me introduce you to Confetti Squares: Creamy peanut butter and butterscotch chips melt and give way to squishy marshmallows in this beloved old-fashioned fudge-like treat.
An informal poll of in my Instagram story revealed that 70% of you aren’t familiar with these delicious treats. That tells me they might be a Canadian thing.
Creamy peanut butter butterscotch bares, plump with rainbow colored marshmallows, were on every cookie plate I ever was offered as a kid. You need them in your life.
An Easy, No-Bake Peanut Butter Confetti Square Recipe
All you need to make these scrumptious peanut butter butterscotch treat is a microwave-safe large measuring cup or bowl and a baking pan.
Add peanut butter, butter, and butterscotch chips to the bowl, give them a gentle melt, then pour them over the marshmallows in the pan.
Lining the pan with parchment paper makes for the easiest lifting out and clean-up.
Chill for the Best Butterscotch Peanut Butter Marshmallow Squares
- Not only does refrigerating them help them firm up faster so you can eat them faster, I’d argue that peanut butter butterscotch bars taste better cold. There’s something about a chewy, cold marshmallow against a creamy peanut butter base that really gets me.
- I actually use the refrigerator at two stages. Before I even start the recipe, I toss the bag of marshmallows in the freezer. This ensures they don’t melt when the warm peanut butter-butterscotch mixture hits them.
Confetti Square Ingredient Notes
- Marshmallows: Despite using white mini marshmallows in these pictures, I actually really love these bars with colored variety with fruity flavors. Sounds crazy. Tastes delicious.
- Peanut Butter: Use a tasty peanut butter. Not the gritty kind you grind yourself at the grocery store that has no salt and uses (semi-rancid) unroasted peanuts. I actually prefer salted in this recipe. It adds a nice contrast to the sweet butterscotch. Regular creamy peanut butter is perfect.

Never heard of these. But I was thinking, possibly warming the peanut butter and butter scotch mixture slightly too slightly melt the marshmallows.
And I like the idea of the colored marshmallows for a festive holiday treat.
I wonder how it would work with almond butter
Yes it does! 🙂
This sounds similar to what I had as a kid but it was chocolate with colored marshmallows and was called Stained Glass Window treats. Haven’t thought about those or seen them made in a long time.
Oooh yes, that name for them rings a bell, too! So nostalgic, right? I hope you make them sometime 🙂
Super easy, fast and yummy. Loved that I could use the microwave to make these. I put the bag of marshmallows in the freezer for maybe 10 minutes while I lined the pan and melted the other ingredients. Then I put the marshmallows in the bowl with the melted stuff, quickly folded them in and then spread in the pan rather than trying to stir in the 8×8 pan. Because the marshmallows were so cold, they didn’t melt during the folding process.
Could I add Rice Krispie cereal without messing these up? I feel like it could be a nice little crunch. Maybe a cup or two?
Hi Laura, yes you could for sure! I would start with 1 cup to make sure there’s enough chocolate mixture.
