Easy Peanut Butter Marshmallow Squares
These classic Butterscotch Peanut Butter Butterscotch Marshmallow Squares are one of my favourite nostalgic childhood treats. Creamy peanut butter and butterscotch chips mixed in with rainbow coloured marshmallows are truly a match made in heaven!
These No Bake Peanut Butter Marshmallow Squares are from my repertoire of my Grandma Yvette’s recipes, she was the baking and cooking queen! Having treats ready for company at any time was really common in my grandma’s house.
If you stopped by there would always be a fresh batch of her famous Chocolate Chip Cookies, her mouth watering Gluten Free Lemon Poppyseed Muffins, her amazing 5 Ingredient Peanut Butter Balls or her Peanut Butter Butterscotch Marshmallow Squares!
I’m actually not the biggest fan of butterscotch. But when it comes to these bars, I AM OBSESSED.
I’m convinced it has something to do with the salt in the peanut butter, which makes the butterscotch less sweet and butterscotch-y. Instead all I taste is creamy, marshmallow goodness!
This recipe goes by a lot of different names. Peanut butter marshmallow bars, confetti squares, no bake goodie bars, etc.
Whatever you choose to call them, they are extremely popular to make for the holidays!
Ingredients for the Easy No Bake Squares
- In a large pot over medium-low heat, combine the butterscotch chips, peanut butter and butter. Stir frequently until the mixture is completely melted.
- Let cool, and fold in marshmallows and vanilla quickly. I like to throw my marshmallows in the freezer for 10 minutes before this step to prevent them from melting all together.
- Pour the mixture into a lined 8×8 or 9×9 inch pan and spread evenly. Refrigerate for 1 hour minimum to set, then cut into bars. Store in refrigerator or freezer (I actually prefer mine straight from the freezer).
Tips for the Best Butterscotch Peanut Butter Marshmallow Squares
Typically before I start making the recipe I throw the bag of marshmallows in the freezer. This way the marshmallows don’t melt when the peanut butter mixture is still slightly warm and hits them.
Not only does refrigerating them help them firm up faster so you can eat them faster, but these squares taste way better cold. The creamy peanut butter base with the cold marshmallows is just a match made in heaven!
Believe it or not, these are even BETTER when they are frozen.
I like using crunchy peanut butter for this recipe because it gives the bars a nice crunch. Also ensure to use a tasty peanut butter, preferably a salted one for this recipe!
The combo of the salt from the peanut butter and sweetness from the butterscotch chips is amazing.
It’s a quick recipe that comes together within 5 minutes and probably takes about an hour to set before you can cut them into bars. But you can speed up the cooling time by sticking the bars in the fridge!
Or if you live in a cold climate like me, stick them outside or on your porch, which acts as a second fridge all winter season.

Hi Joanne,
They are so nostalgic for me as well because my grandmother used to make them for us all the time! Thanks so much for the 5 star review! 🙂
Easy recipe and now my new favourite dessert! Thanks for sharing this recipe.
⭐️⭐️⭐️⭐️⭐️
Hi Eileen,
Thank you so much for the 5 star review and I’m so happy to hear you loved them!!
Can the butter be omitted
Hi Elsie!
No it cannot. You could use vegan butter as a replacement if you like! I haven’t tested with coconut oil or anything else! Happy baking!! 🙂
I used chocolate chips with the butterscotch chipits. It cuts down on the sweetness. Also added slivered almonds and rice crispiest for that extra crunch. Taste amazing.
Hi Katherine, thank you so much for the 5 star review! That sounds amazing! So glad you enjoyed them!!
I seriously cannot get over these!! They bring me right back to my childhood. My nana made these for me when I was growing up and I always wished I got the recipe from her… so thank you so much!!!
Hi Jenna, I’m so happy to hear that! They remind me so much of my grandmother as well! Happy baking! 🙂
Word to the wise: if you double the recipe, don’t double the marshmallows as well…woops.
Yes you do have to double the marshmallows otherwise the filling gets too sweet. Having said that…to each their own.
Can you use Carmel chips..thanks…
Hi Julie, yes you could, however it will yield a completely different flavour. The difference between caramel and butterscotch is that caramel is made with white sugar, but butterscotch is always made with brown sugar. The recipe will stay resemble the same and hold up great it just won’t taste the same!
Delicious and easy! Just like my husbands mom used to make. Needed to make a third batch before Christmas!!!!
Hi Janelle!
I can relate they are always a favourite around Christmas time!! Thank you so much for the 5 star review!!
