Fluffernutter Bars are a decadent and fun dessert that tastes like the fluffernutter sandwiches we loved growing up! A soft peanut butter bar is topped with marshmallow buttercream!
I have to tell you guys I am completely obsessed with these Fluffernutter bars! You can’t go wrong with the classic combo of peanut butter and marshmallow fluff. These bars are just like sinking your teeth into the softest peanut butter cookie you can imagine, that’s topped with a dreamy layer of marshmallow buttercream.
This recipe comes from my very talented friend Allison’s, brand new cookbook! She is the blogger behind Tornadough Alli and her book of mouthwatering dessert recipes is a must-have for baking season this year. It’s up for grabs as of today too ——> Untraditional Desserts 100 Classic Treats With A Twist.Â
I’m loving this book because it’s full of 100 creative dessert recipes that I haven’t ever seen before. We have a copy of it on our coffee table and it’s become the center of conversation anytime guests come by! The fluffernutter bars were first on my list because I simply love peanut butter so much. Like most all of the desserts in this book, they are so simple to make too! I’ve already ordered extra books to give out as Christmas gifts to all the bakers in my life and I can’t wait to see them enjoy it!
Enjoy!

Fluffernutters are a BIG deal here in Massachusetts – and these bars are proof of why. They look amazing!
OMG marshmallow, buttercream, all in one delicious bar… Not only for kids, right? Love it!
That is amazing way to use all the peanut butter. This definitely sounds new to me but it looks absolutely delicious!
This would be so hard to resist!
Whata blast from the past. I remember the joy of a fluffernutter sandwich in my lunchbox. The perfection of bananas, peanut butter, and marshmallows was like dessert on bread. Hah! Looking forward to giving this reconstructed version a go.
Those would be gone in an instant in my house.
