Fluffernutter-Butter Bars

I took a simple old favorite and set out to make it something special. My family took one look and couldn't wait to dive in -- and they didn't! They had some before dinner, they had some after dinner.. Definitely a win :) I hope you enjoy these as much as we did -- with a little more self-control :D

Oh wow! These are sure to be a hit whenever you serve them. We used almond butter in these and it was delish. Quick & super easy to make. The peanut butter chips and the peanut butter cups on top put these over the top! The Test Kitchen

    Rce Krispies cereal
  • 1 1/2 c
    mini marshmallows
  • 1 c
    graham cookies, broken (like teddy grahams)
  • 1 pkg

How to Make Fluffernutter-Butter Bars


  1. Unwrap the peanut butter cups and do a rough chop to make small, bite-sized pieces, but not too small. Set aside.
    Note: I used miniatures, but original size would work just as well. If you're in a mad rush you can use the unwrapped Minis, but you won't get the same richness.
  2. In extra-large microwaveable bowl heat butter and 5 c. marshmallows on high 2 min. Stir. Heat one minute more. Add nut butter and stir until smooth. You may need a few additional seconds in the microwave.
    Note: You'll need two bags of mini marshmallows.
  3. Add cereal, stir until well coated. Quickly fold in 1 1/2 c. marshmallows, and broken graham cookies.
    Note: We're wheat sensitive, so I used Barbara's Bakery Oatmeal Snackimals, but any graham-flavor cookie would work.
  4. Press lightly into 9" square pan that has been greased or coated with food release spray. Try not to compact too much -- this will make them harder to cut later. Set aside.
  5. Put the peanut butter chips into a small microwaveable bowl with the coconut oil. (The coconut oil is not necessary, but gives a nice smooth texture that firms but doesn't harden.)
    Microwave on high 1 minute. Stir. Microwave 1 minute more, stir til smooth and all chips are melted. If necessary you can microwave a few additional seconds at a time, sitrring between, until they're melted.
  6. Spread peanut butter yumminess evenly over the cereal layer.
  7. Cover the top with the chopped Peanut Butter Cups, and press lightly into the melted layer, so they'll bind, and not fall off.
  8. Refrigerate at least an hour, to allow everything to set together. Remove, and let set at room temperature 15-30 minutes. Cut and serve, and enjoy eye-rolling and happy mumbles :)
