A decadent treat is minutes away when you start with a box of cake mix. My Fluffernutter Bars take minutes to make, and are ooey, gooey, deliciousness. MORE+ LESS-

There are certain combinations that just go together. Orange and vanilla. Strawberries and chocolate. Caramel and apple. For me, peanut butter and marshmallow is a match made in heaven. I have a feeling that I am not alone. 

When I am craving this glorious combination, I need to have it immediately. My secret to getting these made quickly? My Fluffernutter Bars start with a box Betty Crocker® Super Moist™ yellow cake mix. A few simple ingredients and before I know it, I am indulging my peanut butter marshmallow craving. These bars are ooey and gooey and incredibly tasty. 

In a large bowl, combine Betty Crocker® Super Moist™ yellow cake mix, eggs, peanut butter, and oil.


Using an electric mixer, mix until combined. This will be a thick batter.


Press the batter into a 9x9 pan that has been sprayed with cooking spray.


Bake in a preheated 350° oven for 40 to 45 minutes. Cool completely.


To make the frosting combine butter and marshmallow cream.


Beat until combined and add vanilla.


Gradually add powdered sugar.


Spread frosting over cooled bars.


Slice and serve. Enjoy!
