Fluffernutter Bars

I should warn this is basically Fluffernutter on steroids, so aside from melting marshmallows and folding in some peanut butter, I also threw in chopped up Nutter Butter, chopped up Reese’s Peanut Butter Cups and mini marshmallows. It’s like peanut butter fudge meets a Fluffernutter.

This past weekend was madness for us. I came from work on Friday night and Matt stopped me before I could come in to tell me some heartbreaking and painful news that’s too difficult to share until we can resolve it. So being the weekend and without any resources to handle what has come our way I baked through the night for some calming therapy.

Thank goodness for baking and blogging to calm my racing mind while I wait for Monday to come. I’m hoping what seems catastrophic and devasting now will give way to professional reassurance that everything will be fine.

Cole has no idea what is going on, but I still wanted to give him a little piece of sweet happiness, so I made these bars for him since he absolutely loves Fluffernutter. Oddly, he did not initially like them. He said they were too big to eat – makes sense for his little mouth, so I sliced them into little matchstick-size bars and he loved them.

A few notes:

  • To shortcut the hands on time and avoid chopping up the regular size Reese’s cups, use mini Reese’s cups.
  • The Fluffernutter Bars can be prepared a day in advance and will keep for up to 2 days once made.

    Naomi, I am so sorry to hear that something is majorly wrong in your world and I hope you get some resolution whatever is going on.

    On a lighter note, these are perfect: Nutter Butters, Reese’s, and Marshmallows…all in one. And nobake. Love it.

    I have some nobake Nutter Butter Bars I make, and just made Smores Bars, but you combined them into one awesome looking treat. I want to try these!

    My son found this recipe on Stumbleupon, and thought we should try it so I made it for Superbowl. There is either something wrong with the recipe or something wrong with the baker (me). I followed it exactly and when I got to the stage where you add the pb chips to the melted butter/marshmallow mix, it all turned into a big dry ball of goo. There was no “pouring” this onto the dry cut-up items. I literally had to press the mix between my fingers to get it to adhere to each other. I did press it into the 8×8 pan, but when I tried to lift out a bar, it all crumbled into dry pieces. My husband suggested I just throw the whole thing back onto low heat, and stir it up, so I did, and of course, the initial chopped ingredients then melted together until it became…a ball of goo. So. I don’t know what I did wrong. Please advise. (I had it on low gas heat)Thanks!

      Hi Terri- Hmm, you had it low heat as well-my guess is the Reese’s peanut butter chips seized. Did you melt the marshmallow and butter first? If so, here’s my suggestion-next time try melting the marshmallows and butter separately, then pour it over the Reese’s peanut butter chips and let it stand for about five minutes. Then return the combined mixture over low heat and stir it continuously until the Reese’s peanut butter chips are fully melted and combined.

    Looks fab but what are Nutter Butter sandwich cookies? I’ve never heard of them here in the UK.

      Fluffernutters are like Oreos but made peanut butter style.

    Oof, my Nutter Butters are stale. (I don’t know , either.) Still usable in these bars or do you need the crunch?
