Fluffernutter Bars Recipe
First, watch our quick demo video to see how we made our fluffernutter bar recipe. Then, keep reading for photo step-by-step instructions and free printable recipe card.
Preheat oven to 350°F and prepare a square baking pan with parchment paper
Cream butter and sugar until fluffy. Add peanut butter, vanilla, and egg and continue mixing until incorporated.
Add flour and mix until well combined. Fold in chocolate chips by hand.
TIP: We made our Fluffernutter Bars batter from scratch so we could add even more peanut butter to the mix! However you could save time by using pre-made cookie dough.
Cookie dough in baking pan
Use a spoon or spatula to even out 2/3 of the cookie dough in the bottom of your prepared baking pan, then top with a layer of Reese’s cups, marshmallow fluff, and another layer of cookie dough.
Often we use non-stick spray alone for baking; however, in this case, parchment paper allows the bars to pop right out of the pan for easier cutting.

An irresistable combination of peanut butter, chocolate, and creamy marshmallow fluff — Reese's Fluffernutter Bars take the ooey-gooey dessert game to the next level!
Ingredients
1/2 cup butter softened
1/3 cup peanut butter
1 cup packed brown sugar
1 egg
1 teaspoon vanilla extract
1 1/4 cups all purpose flour
9-12 Reese’s Cups regular size (not fun size)
2/3 cup chocolate chips
1 container marshmallow creme 7 ounce container
Instructions
How to make Peanut Butter Fluff Bars
Preheat oven to 350°F.
Line an 9-inch square baking pan with parchment paper, allowing the parchment paper hang over all the edges of pan, so that you can use it to pull the bars out of the pan later.
To make the peanut butter fluff dough:
Combine the butter and sugar in a large bowl and beat until light in color and fluffy consistency (about 3 minutes).
Add the egg, peanut butter and vanilla, continuing to mix.
Add the flour and mix until well combined.
Fold in chocolate chips. (You can also toss in a few chopped up Reese's cups for extra chocolate & peanut butter goodness!)
Press about 2/3 of the dough into the bottom of the baking dish. Unwrap and place Reese’s peanut butter cups evenly over the dough.
Spread the entire container of marshmallow creme over the layer of Reese's cups.
Cover with the remaining dough and gently press to spread evenly.
Bake for 25 minutes at 350°F until the crust starts to turn golden brown. Remove from oven, keeping bars in the pan for an hour. This allows them to slowly cook a little more until they cool to room temperature.
