Ingredients
To create these delightful Fluffernutter Bars, you’ll need the following ingredients:
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 3/4 cup unsalted butter (softened)
- 3/4 cup brown sugar
- 1/3 cup white sugar
- 1 1/2 cups smooth peanut butter
- 1 large egg
- 1 large egg yolk (in addition to the other egg, discard the white)
- 7 oz jar marshmallow fluff
How to Make Fluffernutter Bars
Step 1: Preheat the Oven
Preheat your oven to 350F degrees. Position the oven rack in the middle so that heat circulates evenly around your bars.
Step 2: Prepare Your Pan
Line a 9×13 inch pan with parchment paper, ensuring there’s some overhang around the edges. Alternatively, you can line it with aluminum foil and lightly grease it.
Step 3: Mix Dry Ingredients
In a medium bowl, whisk together:
flour
baking powder
salt
This step ensures even distribution of leavening agents throughout your batter.
Step 4: Cream Butter and Sugars
In a separate large bowl, beat together:
butter
brown sugar
white sugar
Mix until soft and fluffy. This creates a light texture in your fluffernutter bars.
Step 5: Add Peanut Butter and Eggs
Mix in:
peanut butter
Then add:
egg
egg yolk
Beat until everything is combined smoothly.
Step 6: Combine Dry and Wet Ingredients
With your mixer on low speed, gradually mix in half of the dry ingredients into the peanut butter mixture. Repeat with the remaining flour until fully incorporated.
Step 7: Reserve Batter
Remove about one cup of batter from the mixing bowl. Set this aside for topping later.
Step 8: Press Dough into Pan
Press the remaining peanut butter dough evenly into the bottom of your prepared pan. This will be your base layer.
Step 9: Bake Base Layer
Bake this layer in your preheated oven for about 25 minutes or until it appears fully set on top.
Step 10: Spread Marshmallow Fluff
After removing from the oven, carefully spread the entire jar of marshmallow fluff over the warm peanut butter layer.
Step 11: Top with Reserved Dough
Pinch off pieces of your reserved peanut butter dough. Flatten them slightly into discs about one inch wide and arrange them on top of the marshmallow layer. Aim for approximately an 80-90% coverage.
Step 12: Bake Again
Return your pan to the oven and bake for another 10 minutes or until this top layer is also set.
Step 13: Cool Before Slicing
Remove from oven and allow cooling at room temperature for at least one hour before slicing into bars.
Step 14: Lift Out of Pan
Use the overhang from parchment paper or foil to lift out your cooled bar slab onto a cutting board.
Step 15: Slice Your Bars
If desired, lightly grease a sharp knife with non-stick cooking spray to help prevent sticking while slicing through those gooey marshmallow layers. Enjoy!

- Skipping the parchment paper: Not lining your pan can make it difficult to remove the bars later. Always use parchment paper or aluminum foil with overhang for easy lifting.
