Close up of Butterscotch confetti bars.

This is another tasty dessert which I had never experienced until we visited my husbands parents. My beloved mother in law would serve these butterscotch confetti bars along with many other delicious treats. I only learned a few years ago that this easy dessert is one of my husbands absolute favorites!

For this quick, easy dessert, I use natural crunchy peanut butter. The crunch from the peanut pieces is such a great texture addition. Of course, smooth peanut butter is great too. I always use salted butter in this recipe. Really, this easy dessert recipe always tastes amazingly yum! One mistake that I have made is to mix the marshmallows in too soon, before the peanut butter mixture cools enough…still tastes great but the marshmallows start to melt and don’t look as pretty:-)

Butterscotch Chip Shortage…

Last Christmas I had Butterscotch Confetti Bars on my list of about 40 treats to make. Fortunately, I had 1 bag of butterscotch chips in the cupboard. I was able to make 1 small batch, but, of course I wanted 80, not only 40 squares in the freezer! I searched every single grocery store that I could here in Calgary and could NOT find butterscotch chips! I’m still not sure why there was this butterscotch chip shortage, but, now I keep a bag in the cupboard at all times!

These peanut butter and marshmallow squares freeze very well. I have had them keep up to 4 months in a sealed container in the freezer. (As long as the container is hidden well)

History of Butterscotch Confetti Bars

Butterscotch Confetti Bars or peanut butter marshmallow squares originated in Canada! Some say these quick and easy no bake dessert squares are an old fashioned Canadian prairie childhood treat. Others claim they are a retro recipe from the Maritimes. Whichever history you believe is up to you, I just know these butterscotch confetti squares are a true Canadian favorite, just like Puffed Wheat Squares!
