Peanut butter…check. Butterscotch…check. Mini marshmallows…check. Gangs all here! You wouldn’t think that an ingredient list so short could create such magicalness, but I kid you not when I say that confetti squares are exactly that: pure magic!

I have vivid memories of walking up and down the aisle of the local Christmas craft fair with my family every year and spying these rainbow coloured confections on the table of every grandma there. Without fail, there next to the handmade crochet dishcloths were Styrofoam plates piled high with confetti squares just begging to be bought.

I now find myself whipping up a batch of these no-bake confetti squares every so often to bring back a rush of those sweet nostalgic childhood memories. Not to mention that I am “All-Star” baker mom and wife when I make these much to the joy of my children and husband. I would never confess to them how incredibly simple they are. Let’s keep that our little secret, shall we.

Gather up these few simple ingredients, pick a bottle of brightly coloured sprinkles, and prepare a square that will impress young and old alike.
