These Stuffed Peanut Butter Rice Krispie Treats are an amped up version of the dessert I craved when I first went off to college. I was inspired by my mom’s version made with cooked Karo syrup and sugar instead of marshmallows.
I upped the ante by adding a layer of Reese’s Peanut Butter Cups. This was a genius move, in my humble opinion!
Stuffed Peanut Butter Rice Krispie Treats
I’ve said it before, but I cannot stomach a peanut butter sandwich. My youngest sister would eat peanut butter out of the jar with a spoon. I think all my kids would, too. Ick.
But put a pan of peanut butter Rice Krispie treats in front of me and I go weak in the knees. I’m not sure it was the minute amount of protein that made me long for these when I was in college or just their sheer deliciousness, but they were constantly on my mind. My collegiate diet consisted of a lot of popcorn and pizza—I’m certain there were a few nutritional deficiencies! These peanut butter cheesecake bars are another fabulous peanut butter treat!
So when it was decided that this week’s Sunday Supper theme was Back to School, these cereal bars came to mind. But I had to make them even MORE enticing by adding a layer of peanut butter cups! Stuffed Peanut Butter Rice Krispie Treats take this classic to another level!!
A Few Tips for Making these Peanut Butter Rice Krispie Treats
- This batch of Stuffed Peanut Butter Rice Krispie Treats filled an 8 x 8-inch pan to the brim. When making these again, I’d go for a slightly shorter version in a 9 x 9.
- You must work quickly after you stir the sweetened peanut butter mixture into the Rice Krispies so it doesn’t start to harden.
- PRO-Tip: Don’t compact the layers too much, either, just gently press. It’s OK if the top is a little uneven. Just call them rustic. Grease your hands so the mixture does not stick when you’re spreading them out in the pan.
- I frosted these with a ganache made with butter, cream and chocolate, but my mom’s original recipe called for melted chocolate chips. Feel free to use that shortcut if you’d like. The topping will not be as glossy, though, with chocolate chips.
- My mom’s version called for Special K, a cereal that looks like Corn Flakes. I think they’re even more irresistible with Rice Krispies!
