Easy Butterscotch Peanut Butter Confetti Squares Recipe

As much as I love trying new and different foods and recipes, there’s just no beating a classic.

And in our house, peanut butter has always been a classic choice for my recipes, whether I’m making a simple batch of peanut butter cookies or a savoury Thai Peanut Beef recipe.


So, when I recently decided I was in a peanut butter mood, choosing just one recipe to make was no easy job!

But I was in a nostalgic mood and craving something sweet, so I decided to make my very favourite easy Butterscotch Peanut Butter Confetti Squares recipe!

Every bite of these smooth, dreamy butterscotch and peanut butter squares studded with rainbow marshmallows is pure bliss.

And when I was a child, they were the treat I was most excited to have when I went to my best friend’s house (since my own mom didn’t make them).

Of course, it didn’t take me long to learn to make these practically-foolproof squares myself.

And while I started out mixing nothing but marshmallows into my squares, I soon learned that just a half-cup or so of Rice Krispies made the squares even better. If you’ve made these before but haven’t ever added Rice Krispies, do it now!

But even if you make this Butterscotch Confetti Squares recipe in its most classic form, you’ll be amazed by how delicious four simple ingredients can be when they’re combined.

What Are the Ingredients in Confetti Squares?

Like most easy recipes, there’s no long list of ingredients when making these squares. All you’ll need is:

  • Butter or margarine
  • Peanut butter
  • Butterscotch chips
  • Rainbow marshmallows

What Else Can I Add To Butterscotch Confetti Squares?

One of the best things about Butterscotch Confetti Squares is that they’re easy to customize with all kinds of different mix-ins. Some of my personal favourites are:

  • Rice Krispies
  • Coconut
  • Crushed Potato Chips

Convinced you need to make this right now? You’re going to love how easy these tasty squares are!

Confetti squares are one of those recipes that take virtually no skill to make. Just make sure that the melted butterscotch mixture isn’t too hot when you stir in your marshmallows to avoid accidentally melting them.

And, of course, make sure to wait until the squares are completely cooled before cutting! This is one of the hardest parts of making butterscotch confetti squares as far as I’m concerned, so I’ll often pop the tray into the freezer so that the squares set quicker and I can dig in!

    1. Hi Shirley! I’ve frozen them with the rice krispies, and they don’t go mushy at all! I’m guessing it’s since there’s no actual liquid to speak of in the squares, just fat and sugar. ;) Hope this helps!

  1. I have not thought of these in years, my Aunt made these with chocolate chips, once in the pan she quickly sprinkled a very small amount of coconut on top she said it was snow on a rocky road

    1. Oh that’s such a fun concept! A friend from high school that was a pastry chef made these at her bakery and mixed both coconut and rice krispies in with the marshmallows; SO good! But I love the idea of adding coconut on top too, that’ll be my must-try next time I make them. :)

    1. Hi Vicky! Even though I already emailed you the answer, I thought I’d respond to your comment as well in case anyone else had the same question. About 5 cups of marshmallows should be perfect!

  2. I remember seeing these but never trying them when I was little. Love how colorful they are plus they have all my fave ingredients.
