Fluffernutter Bars – Delicious peanut butter bars topped with marshmallow frosting! These bars are a great afternoon snack or holiday treat!
Fluffernutter Bars
Can I just say how amazing these fluffernutter bars are?! This recipe is coming at you straight from Allison Miller from Tornadough Alli‘s brand new cookbook Untraditional Desserts – 100 Classic Treats with a Twist. This cookbook came out just last week and has such awesome recipe in it! In addition to fluffernutter bars, some of my other favorites from it include french cruller dippers, lemonade puppy chow, tiramisu cookies, and shirley temple cake! Go check it out by clicking HERE!
When I was flipping through the cookbook, I was immediatly drawn towards the fluffernutter bars. I had been on a marshmallow kick after that rockin’ marshmallow frosting on the hot chocolate cake from a few weeks back so when I saw this recipe used peanut butter AND marshmallows, I was sold.
This recipe is super easy to make and you can easily half the recipe if you want a smaller batch of 9 bars instead of 15. If you do that, use an 8×8 inch pan and make sure you remember to half the frosting recipe too!
Some fun toppings for these bars are crushed peanuts and/or mini marshmallows. I used tiny ones that are the size that normally comes in hot chocolate packets.
