Ingredients in Confetti Squares

Here’s the magic lineup that makes these bars so special:

Butterscotch Chips: Sweet, rich, and melty—this is the base of that caramel-y flavor.

Peanut Butter (smooth): Adds creaminess and a nutty depth that balances the sweetness.

Salted Butter: Keeps things smooth and adds that irresistible salty-sweet balance.

Vanilla Extract: Just a splash enhances all the flavors.

Salt: A pinch sharpens the sweetness and rounds everything out.

Rainbow Mini Marshmallows: The star of the show—soft, chewy, and colorful. They turn every bar into a little slice of happiness.

Instructions

Making Confetti Squares is as easy as melt, stir, fold, and chill. Here’s how:

Melt the Base: In a large saucepan over low heat, combine the butterscotch chips, peanut butter, and salted butter. Stir constantly until smooth and melted. (You can also do this in the microwave in short bursts, stirring in between.)

Add Flavor: Remove from heat and stir in the vanilla extract and salt. This takes the mixture from good to unbelievably good.

Fold in Marshmallows: Let the mixture cool slightly (so the marshmallows don’t melt), then gently fold in the rainbow marshmallows until evenly coated.

Press Into Pan: Line an 8×8 or 9×9 pan with parchment paper. Press the mixture evenly into the pan, smoothing the top.

Chill: Pop the pan into the fridge for about 2 hours, or until firm.

Slice and Serve: Cut into squares and watch them disappear!
