These confetti squares flew off the plate at our potluck dinner - gone faster than anything else on the sweet table! There's something magic about mixing butterscotch, peanut butter and those tiny rainbow marshmallows that hits the spot for everybody from little kids to grown-ups.

My next-door neighbor's kid was jumping up and down with joy when she tried one, and my hubby (who swears he doesn't like desserts) snuck three while I was busy in the other room!

What You'll Need

  • Butterscotch chips: They're the backbone of the flavor. Don't swap them for white chocolate - it won't turn out right!
  • Peanut butter: Creamy gives you that velvety feel, but chunky adds some nice texture if that's what you like.
  • Butter: The salt in salted butter cuts through the sweetness. If you've only got unsalted, toss in a tiny bit of salt.
  • Vanilla extract: A small splash brings everything together without standing out too much.
  • Mini marshmallows: The rainbow ones truly make these "confetti" squares. Surprisingly, the fruity flavors work really well with the butterscotch.

How I Make Them

Melt It Right

I grab a thick-bottomed pot and keep the heat low while melting the butterscotch chips, peanut butter and butter together. Don't rush this part - high heat can make your butterscotch clump up or turn bitter.

Marshmallow Trick

You need to let the mixture cool a bit before dumping in the marshmallows. Too hot and they'll dissolve completely, too cold and you can't mix properly. I just touch it with my finger - when it feels warm but doesn't burn, that's the sweet spot.

Smart Setting

I put parchment paper in my pan with extra hanging over the sides. This way I can lift everything out easily when it's time to cut. A quick spray of cooking oil on the paper means nothing will stick.

Smooth Slicing

For really pretty squares, I make sure they're totally chilled, then use a big knife dipped in hot water (and dried off) between cuts. You'll get those Instagram-worthy clean edges.

I first had these at my friend's house from Canada - they're apparently a big thing there where folks call them "marshmallow squares" or "peanut butter marshmallow squares." Now I bring them to every get-together when I need something fast that looks like I tried harder than I did!

Serving Ideas

They're fantastic by themselves, but sometimes I pair them with a scoop of vanilla ice cream for a fancy dessert. They work great at bake sales, for classroom snacks, or on holiday cookie trays. I've even broken them up as an ice cream topping - it's so good!

Make It Your Own

Try mixing in a spoonful of Nutella before it hardens for a chocolate twist. Throw in some Rice Krispies if you want more crunch. For a boozy version, add a few spoonfuls of bourbon with the vanilla. During holidays, grab season-colored marshmallows (red/green at Christmas, orange/black at Halloween) to match the occasion.

Storage Smarts

They stay fresh in a sealed container at room temp for many days, though they rarely hang around that long! If you want to save them longer, freezing works great - just put paper between layers so they don't stick. I often make twice as much and freeze half for when surprise guests drop by.

And they're almost impossible to mess up - perfect when you need a guaranteed hit without any kitchen stress!

Recipe FAQs

→ Is it okay to swap marshmallows?
Sure! Use regular white minis or chop up full-sized ones if needed.

Your butterscotch mix might've been too hot. Cool it slightly first, but not too long.

Absolutely! Almond butter or any nut butter will do just fine.

Yep! Pop them in an airtight container in the fridge for up to a week.

You bet! They'll keep in the freezer for three months. Just thaw first.

Ingredients

→ Main Ingredients

01 1¼ cups creamy peanut butter
02 1⅓ cups butterscotch chips
03 2 teaspoons vanilla flavoring
04 6 tablespoons salted butter
05 14 ounces colorful mini marshmallows
06 ½ teaspoon table salt

Steps

Step 01

Put parchment paper in a 9-inch square pan and give it a quick spray with oil.

Step 02

Throw the peanut butter, butterscotch chips, and butter into a saucepan. Use medium-low heat and stir all the time until the chips are melted and it's smooth.

Step 03

Pour in the vanilla extract and salt, then stir until blended well.

Step 04

Scoop out and keep 1 cup of marshmallows on the side. Gently add the rest to the warm but not too hot mixture, folding to combine without melting everything.

Step 05

Firmly pack the mixture into the pan you prepped earlier. Sprinkle the saved marshmallows on top and lightly press them in so they stick.

Step 06

Chill it in the fridge until firm, about an hour. Once it's set, slice into squares and enjoy.

Helpful Notes

  1. You can slice up big marshmallows if minis aren't on hand.
  2. Keep leftovers in a sealed container in the fridge for up to seven days.
  3. Be quick when adding marshmallows so it doesn't set too early.
