How do you make Fluffernutter Bars?

 

Making these Fluffernutter bars is really easy. The peanut butter bar is soft, chewy and dense and the marshmallow icing is sweet and creamy. Personally, I like anything that has peanut butter included but these cookie bars are a great treat all year long.

Make the frosting – Blend together all the ingredients for the marshmallow icing in an electric mixer.

Spread evenly on the peanut butter cookie bars.

Can you freeze Fluffernutter Cookie Bars?

Yes! Which makes this dessert even better in my opinion. I like to cut mine into squares and freeze in a zip top freezer bags. Be sure to do this WITHOUT the icing.
