    AKA Kasper Krispies, these super easy no bake bars are a favorite among my friends! They only use 4 ingredients and can be whipped up in less than 10 minutes! The white chocolate and peanut butter melt into a delicious unique flavor and coat the mini marshmallows and Rice Krispies perfectly. These are so much better than your average Rice Krispie Treat!

    I first called theses Kasper Krispies because my high school AP calc teacher, Mrs. Kasper, used to make them for our class. I couldn't remember what she called them or the exact recipe, so I got as close as my memory would take me & named them after her! They're now known as Kasper Krispies to my close friends and I, but I changed the name to be more descriptive of the dessert so that everyone can more easily discover these tasty treats!

    Chocolate Peanut Butter Rice Krispie Ingredients

    Making these bars could not be simpler. First you'll want to line an 8x8 inch pan with parchment paper or aluminum foil so that it hangs over the sides. Then, combine the marshmallows and Rice Krispies in a large bowl. Melt the creamy peanut butter and white chocolate chips together in the microwave and then stir it into the cereal combo. Pour the mixture into your prepared pan, top with extra white chocolate chips, and refrigerate for a few hours! They can be cut into 9 larger or 16 smaller squares.

    Tips & Storage:

    Can I swap the white chocolate chips for a different kind?

    Of course! Feel free to use milk, semi-sweet, or dark chocolate chips instead (or a mix of multiple!)

    Do the marshmallows or Rice Krispies get soggy in the melted peanut butter chocolate?

    Not at all! They both keep their shape & texture very well so the bars are soft & crunchy!

    Can I adjust the ratios of the ingredients?

    Yes, this recipe is easily adjustable! Feel free to add extra cereal for more of a crunch, change the chocolate peanut butter ratio, or whatever you like!

    How do I make a bigger batch of these?

    You can make these in a 9x13 inch dish. Double the ingredients for thin bars, triple them for thicker bars.

    Are these gluten free?

    They can be! Be sure to use Rice Krispies Gluten Free cereal and gluten free marshmallows.

    How should I store these?

    In the refrigerator for up to 1 week or in the freezer for up to 2 months. They can get pretty melty if left at room temperature.

    • 2 cups Rice Krispies cereal
    • 2 cups mini marshmallows

    Instructions
     

    • Melt the peanut butter and white chocolate chips together in a medium-sized microwave safe bowl (30 seconds at a time, mix after each interval until they're melted).

      Used gluten-free rice crispies to make the recipe GF. So delicious and easy to make! Definitely will be making these again in the future.

      These are as good as it gets - I had two boxes of them and froze one. They tasted just as good a week later. Thanks again Kayla!

      I’d die if I could had these treats every week. They’re so good, I don’t think I could help myself! Peanut butter, marshmallow, what more could you want?!

      They’re the perfect treat that are both crunchy and creamy all in one bite! Since they’re no bake they’re quick and easy to whip up on an afternoon.
