There might not be anything more nostalgic than confetti squares, aka peanut butter marshmalllow squares or butterscotch marshmallow squares.  I remember them fondly from my childhood, but as an adult – I kind of thought ewwwww.

Last year Clint asked me to make them and my answer was a reluctant yes, haha! But, I love my partner so I went ahead and started working on them. I am so glad I did because they’re actually AMAZING.

Who knew they would be so good, and also so easy. They are the perfect no bake dessert to add to your holiday baking. I promise everyone will love them if not for the flavour, definitely for the memories it will bring back.

And if you want to switch it up a notch, you can make chocolate ones too! Just see below for recipe alterations.

Ingredients for this no bake holiday dessert

How to make no bake confetti squares

Melt butter and peanut butter together, stirring every couple of minutes.

Add the vanilla and butterscotch chips while the mix is still warm but not too hot, otherwise the sugars in the butterscotch chips will start to crystallize and the texture will feel a little gritty.

Stir in the rainbow marshmallows once it’s cooled to room temperature. 

Pour into your prepared brownie pan and let harden in the fridge for an hour or two.
