This recipe for peanut butter popcorn will change your life for the better!

Peanut Butter Popcorn in the microwave recipe

I feel like I’m channeling a little Wicked there. Go ahead, sing to your popcorn, “Because I knew you. I have been changed for good!”

It is that good. You will be belting out Broadway tunes while simultaneously trying to find the best hiding spot in your house so you can hoard it to yourself.

I’m not even a huge popcorn lover. My husband is. Holy goodness, is that man a popcorn freak. He even asks for tubs of it for Christmas gifts. Lame-O.

Unless it was a tub of this peanut butter popcorn. That would take him straight from Christmas Gift Loser to King of the Mountain.

I actually found a recipe for peanut butter popcorn on another site, but it contained corn syrup and I’m trying to avoid that as much as I can. Don’t get me wrong, there is nothing that can replace corn syrup in the gooey, caramely goodness that is sticky bun topping. But I was thinking there was a way that I could avoid it here.

So what else would give us that ooey, gooey-ness that we wanted but not overpower the peanut butter flavor? Marshmallows!!

They worked perfectly and we’ve enjoyed this treat once a week in the month since I made it originally. Yanno, recipe testing and all that. ; )
