No Bake Peanut Butter Marshmallow Squares AKA Confetti Bars from @kitchenmagpie

No Bake Peanut Butter Marshmallow Squares / Confetti Bars are from my repertoire of my Grandma Marion’s recipes,  as she was an avid fan of  “dainties”.  Or squares, as most people would call them, but I prefer the word dainties instead, not only because it brings forth very fond memories of my grandma who has sadly no longer with us, but because it also evokes a feeling of times gone by, in which you always had a supply of dainties ready in the freezer in case your neighbour stopped by.  This was really common in my grandma’s rural area;  if you stopped by, there would be a cup of coffee and a plate of squares produced for your chat in less than 10 minutes.

Oh colored marshmallows, how I love thee. Especially the large ones roasted over a campfire, which reminds me, those large colored marshmallows are darn hard to find! This recipe uses just over half of a large bag of the mini variety rainbow marshmallows. When then leaves just under half a bag of colored mini-marshmallows for snackin’. Gotta love a recipe that pulls double duty!

No bake peanut butter marshmallow squares are probably my favourite square on earth and they totally made it into my cookbook even! Now, the cookbook has a NEW version of these bars as well that you will totally have to check out as well.

Those are super deadly and delicious as well! For now though, this recipe is still a winner and my favourite.

The really important question is: are you a butterscotch or chocolate lover when it comes to these bars? You can make both versions easily,my Grandma always had both but I do believe that these butterscotch ones disappeared faster than the chocolate ones did.

And if you can believe it, these are even BETTER when they are frozen!

Happy baking everyone!

    I make these with Sunbutter instead of peanut butter so my daughter can have them too!

    Those always gave me insomnia. I had to wake up 2 or 3 times in the night to nibble on a piece.

    They look absolutely delicious and colourful too! 🙂

  6. I love these bars.  My grandmother always made them with butterscotch chips for me for my birthday.
