How to Make Fluffernutter Bars
-
Preheat the oven to 350°F (175°C). This is key for ensuring those beautiful, golden-brown bars.
-
Whisk together the flour, baking powder, and salt in a bowl. This helps distribute the leavening agent evenly, ensuring your bars rise perfectly.
-
Cream the softened butter, brown sugar, and white sugar in a separate bowl until smooth. The mixture should become light in color, around 2-3 minutes.
-
Mix in the peanut butter until fully incorporated. You’ll want that rich, nutty aroma to fill your kitchen.
-
Beat in the egg and egg yolk until blended. This adds moisture and richness to your delicious batter!
-
Gradually add the flour mixture to the peanut butter mixture, stirring gently until combined. Don’t overmix; you want those fudgy bars!
-
Drop spoonfuls of dough onto a baking sheet lined with parchment paper, spacing them about 2 inches apart. The dough should look fluffy and inviting!
-
Create an indentation in the center of each cookie with the back of a spoon. This is where your marshmallow fluff will go, so make it a nice deep well.
-
Fill each indentation with marshmallow fluff, letting it sit proudly in the dough. The marshmallow will become wonderfully gooey as it bakes!
-
Bake in the preheated oven until golden brown, about 12-15 minutes. Keep an eye on them; you want a perfect balance of texture!
Optional: Drizzle with melted chocolate for an extra touch of sweetness!

Make Ahead Options
These Fluffernutter Bars are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can prepare the dough up to 24 hours in advance; simply mix all the ingredients as directed, then cover it tightly and refrigerate. The unbaked dough maintains its quality beautifully, preserving that rich peanut butter flavor. When you’re ready to bake, scoop the dough onto a baking sheet, create the indentations, and fill them with marshmallow fluff right before baking. This ensures that each bar is just as delicious as if they were freshly made, giving you a warm, comforting treat with minimal effort!
How to Store and Freeze Fluffernutter Bars
Room Temperature: Store your Fluffernutter Bars in an airtight container at room temperature for up to 3 days. This keeps them soft and delicious!
Fridge: For extended freshness, place the bars in the fridge for up to 1 week. Just be sure to wrap them well to avoid drying out.
Freezer: Freeze your Fluffernutter Bars for up to 3 months. Cut them into squares, wrap each piece in plastic wrap, and then place in a freezer-safe bag.
Reheating: To enjoy them warm, simply pop a frozen bar in the microwave for about 10-15 seconds. This will revive that gooey marshmallow goodness!
Tips for the Best Fluffernutter Bars
- Measure Accurately: Spoon your flour into the measuring cup instead of scooping directly. This prevents packing and ensures the right texture for your Fluffernutter Bars.
- Room Temperature Ingredients: Make sure your butter and eggs are at room temperature. This helps everything blend smoothly, resulting in a moist and tender bar.
- Indentation Depth: Don’t be shy with the indentation! Make it deep enough to hold plenty of marshmallow fluff without it spilling over during baking.
- Watch Baking Time: Keep an eye on the bars in the oven. They should be golden around the edges but slightly soft in the center for that perfect chewy bite.
- Cooling Period: Let your Fluffernutter Bars cool completely in the pan before cutting. This allows them to set and makes for cleaner slices.
Fluffernutter Bars Recipe FAQs
What type of peanut butter should I use for Fluffernutter Bars?
Absolutely, I recommend using smooth peanut butter for these bars. It creates a creamy texture and blends seamlessly into the dough. If you’re a fan of crunchy peanut butter, you can use that too, just be aware that it will change the texture slightly, adding some delightful crunch!
How should I store my Fluffernutter Bars?
For optimal freshness, store your Fluffernutter Bars in an airtight container at room temperature for up to 3 days. If you want to keep them longer, they can be refrigerated for up to a week. Just ensure they’re wrapped properly to avoid drying out.
Can I freeze Fluffernutter Bars?
Absolutely! You can freeze your Fluffernutter Bars for up to 3 months. To do this, cut the bars into squares, wrap each piece tightly in plastic wrap, and place them in a freezer-safe bag. When you’re ready to enjoy, simply thaw them in the fridge or microwave for about 10-15 seconds for that gooey marshmallow delight!
What should I do if my marshmallow fluff spills over during baking?
If you find that your marshmallow fluff spills over, it could be due to not creating a deep enough indentation in the cookie dough or overfilling the wells. Next time, make sure to press down firmly with the back of a spoon to create a proper well, and fill lightly with the fluff. If it still spills, don’t worry—just let it cool, and you’ll have delightful gooey edges!
Are Fluffernutter Bars safe for kids with peanut allergies?
Unfortunately, Fluffernutter Bars are not suitable for anyone with peanut allergies, as they contain peanut butter. If you’re looking for an alternative treat, consider using sunflower seed butter as a peanut butter substitute! Just ensure that the marshmallow fluff you choose doesn’t contain any allergens.
Can I use homemade marshmallow fluff instead of store-bought?
Absolutely! Making your own marshmallow fluff is a fun way to personalize your Fluffernutter Bars. To do this, whisk together egg whites and sugar until fluffy and glossy, then gently fold in a bit of vanilla extract. This homemade version can enhance the flavor and freshness of your bars!
