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

Blue Ribbon Recipe

Wow, these are not the marshmallow cereal treats you grew up on. The base is a traditional Rice Krispie treat with the addition of extra marshmallows and the crunch of graham cracker Teddy Grahams. What turns this into a rich and decadent dessert is the topping. And, this is where peanut butter lovers will fall in love. There's a thick layer of melted peanut butter chips and chopped peanut butter cups. So good, you'll find reasons to make these again and again (kids' birthday party, game day dessert, after-school treat, potluck, etc). If you love a fluffernutter, the flavors in these homemade cereal treats mimic the sandwich.

How To Make fluffernutter-butter bars

Test Kitchen Tips
Our microwave was acting finicky and we found the stove easier to get the proper consistency. Just make sure to melt ingredients slowly over low heat.
  • Chopping peanut butter cups.
    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 the 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.
  • Marshmallow, butter, and peanut butter melted.
    In an extra-large microwaveable bowl, heat butter and 5 c. marshmallows on high for 2 min. Stir. Heat one minute more. Add peanut butter and stir until smooth. You may need a few additional seconds in the microwave. Note: You'll need two bags of mini marshmallows.
  • Combining melted marshmallow and Rice Krispies cereal.
    Combine cereal and marshmallows. Stir until well-coated.
  • Folding in marshmallows and graham cookies.
    Quickly fold in 1 1/2 cups 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.
  • Mixture pressed into a pan.
    Press lightly into a 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.
  • Peanut butter chips and coconut oil melted.
    Put the peanut butter chips into a small microwaveable bowl with the coconut oil. Microwave on high for 1 minute. Stir. Microwave for 1 minute more, stir until smooth and all chips are melted. If necessary you can microwave a few additional seconds at a time, stirring between, until they're melted. Note: Coconut oil is not necessary, but gives a nice smooth texture that firms but doesn't harden.
  • Peanut butter chips spread over the cereal treats.
    Spread peanut butter yumminess evenly over the cereal layer.
  • Chopped peanut butter cups pressed into the melted peanut butter chips.
    Cover the top with the chopped peanut butter cups, and press lightly into the melted layer, so they'll bind and do not fall off.
  • Fluffernutter-Butter Bars cut after being chilled.
    Refrigerate for at least an hour, to allow everything to set together. Remove and let set at room temperature for 15-30 minutes. Cut, serve, and enjoy eye-rolling and happy mumbles. :)
