Fluffernutter Rice Krispies Treats

If you’re here you already know what fluffernutter is. It’s the classic combo of marshmallow fluff (marshmallow creme), that comes in a jar, and peanut butter on bread to make a fluffernutter sandwich. Our fluffernutter treats combine the peanut butter and marshmallow flavors and add in rice krispies cereal. Chewy, soft, spongy, loaded with melted peanut butter morsels, and just plain GOOD.

Fluffernutter Rice Krispies Treats Are

Soft and Chewy: the melted marshmallow and peanut butter mixture makes these treats ridiculously soft and chewy.

Loaded with Peanut Butter Flavor: with both peanut butter and peanut butter chips there is no shortage of nutty goodness.

Spongy: My tip for making spongy rice krispies treats is to toss in half of a bag of mini marshmallows at the END. Right before transferring the mixture to the pan. The mini marshmallows melt slightly from the warmth of the melted marshmallow and peanut butter mixture, but not all the way. The bits of mini marshmallows that don’t melt make the treats ultra spongy.

Easy to Make: these treats are a quick, 15-minute dessert.

This recipe makes 12 giant treats. You, of course, can cut them into 24 smaller portions.

How to Make These Peanut Butter Rice Krispie Treats

Stove top directions: heat butter, marshmallows, peanut butter, and vanilla in a large pot on medium to low heat until melted and smooth. Stir in cereal, mini marshmallows, and peanut butter chips using a wooden spoon. Prepare the rest the same as above.
