- 3 cups crispy rice cereal: Adds that signature crunch and lightness to the bars.
- 1 cup creamy peanut butter: Brings rich, nutty depth and moisture, binding the bars together.
- 1 cup marshmallow fluff (marshmallow creme): Provides sweetness and that gooey, dreamy texture.

How to Make Fluffernutter Bars Recipe
Step 1: Prepare the Baking Dish
Start by lining a 9×13-inch baking dish with parchment paper or lightly grease it. This step ensures your bars come out cleanly without sticking, making the cutting and serving process much easier.
Step 2: Melt the Butter
In a large saucepan over medium heat, melt the butter slowly. This gentle heat is crucial to prevent scorching and promotes even mixing in the next steps.
Step 3: Add Peanut Butter and Marshmallow Fluff
Once the butter is melted, stir in the creamy peanut butter and marshmallow fluff. Keep stirring until everything is completely smooth and combined, creating a luscious, shiny mixture that will coat the cereal perfectly.
Step 4: Stir in Vanilla Extract
Remove the pan from heat, then stir in the vanilla extract. This tiny addition lifts the entire flavor profile, making each bite taste extra special.
Step 5: Combine with Crispy Rice Cereal
Gently fold the crispy rice cereal into the peanut butter mixture, ensuring even coating without crushing the cereal. This keeps every bar light yet chewy with that delightful snap.
Step 6: Press into Baking Dish
Now, firmly press the combined mixture into your prepared baking dish. Packing it down well helps the bars hold their shape once set, so use a spatula or your hands covered in parchment for the best results.
Step 7: Let Cool and Set
Allow the bars to cool at room temperature for at least one hour. This resting time lets them set up perfectly so they cut cleanly without crumbling.
Step 8: Cut into Bars and Serve
Once the bars are firm, slice them into your desired size and serve. They’re perfect fresh but also fantastic for later snacking or sharing.
How to Serve Fluffernutter Bars Recipe
Garnishes
A light dusting of powdered sugar or a drizzle of melted chocolate can add visual charm and an extra touch of indulgence to your Fluffernutter Bars. For a fun twist, sprinkle some mini chocolate chips or chopped peanuts on top before the bars fully set.
Side Dishes
Pair these bars with a glass of cold milk or a cup of hot coffee to balance their sweetness. A bowl of fresh fruit like sliced strawberries or apple wedges can also complement the buttery, sweet flavors wonderfully.
Creative Ways to Present
For parties or gifts, cut the bars into bite-sized squares and stack them in decorative boxes or jars with colorful parchment. You can also sandwich a scoop of vanilla ice cream between two bars for a nostalgic frozen treat that everyone will love.
Make Ahead and Storage
Storing Leftovers
Fluffernutter Bars keep well in an airtight container at room temperature for about 3 to 5 days. Storing them properly helps maintain their chewy texture without drying out or becoming stale.
Freezing
If you want to enjoy these bars over a longer period, wrap each bar individually in plastic wrap then place them in a freezer-safe container or bag. They freeze beautifully for up to 2 months and thaw quickly at room temperature when you want a treat.
Reheating
While these bars are typically enjoyed at room temperature, if you prefer a warm, gooier texture, microwave them for about 10 to 15 seconds. Just be careful not to overheat, or the marshmallow layer can become too soft and sticky.
FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, you can substitute crunchy peanut butter if you like a bit more texture in your Fluffernutter Bars Recipe. It will add little peanut bits that give an extra nutty crunch.
Is there a substitute for marshmallow fluff?
If you cannot find marshmallow fluff, you can use mini marshmallows melted gently in place of fluff, although the texture may be slightly different. Just melt them with the butter and peanut butter until smooth.
Can I use natural peanut butter?
Natural peanut butter works, but since it’s less sweet and more oily, the bars might be slightly looser. You can compensate by chilling the mixture a bit longer before cutting.
How do I make these bars gluten-free?
Ensure you use a certified gluten-free crispy rice cereal, as some brands can contain barley malt or other gluten ingredients. The rest of the recipe is naturally gluten-free.
Can I add chocolate chips or other mix-ins?
Absolutely! Adding chocolate chips, chopped nuts, or even dried fruit can personalize your Fluffernutter Bars Recipe and add exciting flavor bursts throughout each bite.
