No more then 10 minutes work and a little chilling time will give you a popcorn twist on a classic krispie treat.

So hi everyone, its been while. Did everyone have a great August? I took a month off from the blog to recharge my batteries, spend some time with family and get a jump on my collage work and I’m still also working full time. Unfortunately as much as I would like to think I am super woman something had to give. So I took a month off from baking and from blogging and am now ready to head full force into the Fall Season. I love Fall, but before we go anywhere near that, lets crack on with these peanut butter peanut butter popcorn squares.

10 Minutes to PB Heaven!

This chewy and crunchy treat really only takes 10 minutes to put together as long as you use a few hacks 😉 I used microwavable popcorn which makes life so easy! Or you could even buy it already popped! Just make sure its either flavourless or at the most lightly salted. I also used the microwave to melt my peanut butter chips, peanut butter and marshmallows. I am not the worlds biggest microwave fan but I do love it for reheating and melting things. Oh and mug cakes 😀 Such a time saver!

Then trow in some peanut butter M&M’s – totally optional but really yummy give it all a quick mix gently pat the mixture into a tin. Pop it in the fridge and an hour later you will be diving into these bad boys 😉

Quick note on vegan / vegetarian marshmallows.

I have had a lot of emails asking about the vegetarian / vegan marshmallows I use in my recipes. They are made from a company called Freedom confectionary they are available in Holland and Barrett stores across the UK and also on Amazon. I am not too sure about any country outside of the UK but I am sure they are out there if you just google them. (No affiliate links, I’m just a fan). Anyway back to the peanut butter popcorn squares.

PB Chips or White Chocolate?

I use peanut butter chips in this recipe, they are not always easy to come by in the UK and when you do find them they tend to be terribly pricy. Not good, I buy mine online at a specialist American food store but they are still not super cheap but at least they are reasonably priced. But if this is too much for you then use white chocolate chips instead. Readily available and really cheap.


Colourful, tasty, chewy and crispy and not all that bad for you, especially if you don’t add the peanut butter M&M’s. Now where’s the fun in that?

So with some renewed vigour for the Fall lets get it on with these peanut butter popcorn squares 😀


Peanut Butter Popcorn Squares
Prep time
Cook time
Total time
Peanut Butter Popcorn Squares are a crunchy and chewy treat made with popcorn and flavoured with peanut butter and peanut butter M&M's.
Recipe type: Afternoon Tea
Cuisine: American
Serves: 12 squares
  • 40 grams plain or lightly salted popped popcorn (6 cups)
  • 85 grams smooth or crunchy peanut butter (1/3 cup)
  • 45 grams peanut butter chips or white chocolate chips (1/4 cup)
  • 17 large marshmallows
  • 90 grams peanut butter M&M's (one 3.2 ounce theatre box / ½ cup)
  1. Line an 8x8 inch / 22x22 cm square tin with baking parchment and place to one side.
  2. If you need to pop your popcorn then do so following the package instructions. Once done place in a large bowl and put aside for the moment.
  3. Either in a microwavable bowl or a bain-marie carefully melt your chips, peanut butter and marshmallows. I did mine in a 800W microwave in 30 second bursts and found a little over 90 seconds did the trick.
  4. Quickly mix everything together and pour it over your popcorn. With a quick but careful hand mix until all of the popcorn has a light coating.
  5. If you are using the M&M's then add half of them now and give them a stir in.
  6. Pour the mixture into your lined tin and pat it gently down so it all sticks together and sprinkle the remaining M&M's over the top and gently press them down to get them to stick.
  7. Place in the fridge for 1 hour, then slice into either 9 or 12 squares depending what size you want.
  8. Kept in an airtight tin at room temperature these will last up to 4 days. Kept in the fridge they should last for 7 days.
