Ingredients You’ll Need
This recipe is wonderfully straightforward, relying on a handful of pantry staples that come together to create layers of flavor and texture that are nothing short of magical. Each ingredient plays a vital role, from the creamy peanut butter that provides richness, to the mini marshmallows that lend delightful pockets of chewiness and sweetness.
- Unsalted butter, 1/2 cup melted: Adds moistness and richness, making the bars tender and flavorful.
- Granulated sugar, 1/2 cup: Provides the right level of sweetness and helps with browning the crust.
- Light brown sugar, 1/2 cup packed: Brings a subtle molasses flavor and keeps the texture chewy.
- 1 large egg: Binds the ingredients together, creating structure and softness.
- Vanilla extract, 1 teaspoon: Enhances all the flavors with a warm, fragrant note.
- Creamy peanut butter, 1/2 cup: The star of the show, giving that classic peanut butter taste and creamy texture.
- All-purpose flour, 1 cup: Provides the base and structure for the bars.
- Baking powder, 1/4 teaspoon: Ensures just enough rise for a soft, cakey crumb.
- Salt, 1/4 teaspoon: Balances the sweetness and enhances the peanut flavor.
- Mini marshmallows, 1 cup: Create sweet, gooey pockets that make every bite fun.
- Peanut butter chips, 1/2 cup: Boost peanut flavor and add melty bits of goodness.
- Chopped peanuts, 1/4 cup (optional): Add crunch and texture contrast for those who love extra nuttiness.
- Marshmallow fluff, 1/2 cup: The creamy, cloud-like layer that makes the bars truly special.
How to Make Fluffernutter Bars: An Incredible Ultimate Recipe
Step 1: Prep and Mix the Wet Ingredients
Start by preheating your oven to 350°F and lining an 8×8-inch pan with parchment paper—don’t forget to leave extra hanging on the sides, so you can easily lift the bars out later. Melt the butter and whisk it together with the granulated and brown sugars until the mixture is smooth and glossy. Add the egg, vanilla extract, and creamy peanut butter, mixing thoroughly until silky and combined. This stage is crucial as it creates the luscious base that all the other ingredients will build upon.
Step 2: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Slowly incorporate these dry ingredients into the wet mixture, stirring just enough to bring everything together. Overmixing isn’t necessary here, as you want to keep those bars tender and soft. Once everything is combined, your dough is ready for the fun part: adding the mini marshmallows and peanut butter chips.
Step 3: Fold in Marshmallows and Add Texture
Gently fold in the mini marshmallows, peanut butter chips, and if you like, the chopped peanuts. This is where texture and fun bursts of flavor really come into play, making each bite exciting. Don’t worry if it looks a bit sticky—that’s exactly what you want!
Step 4: Create the Marshmallow Fluff Layer
Spread half of your dough evenly into the prepared pan, pressing down gently but firmly. Dollop the marshmallow fluff over this base, then use a spatula to spread it out evenly. This luscious layer is what elevates these bars to the next level—creamy, sweet, and oh-so-satisfying.
Step 5: Top and Bake to Perfection
Carefully spread the remaining dough over the marshmallow fluff, pressing lightly so it covers the layer but doesn’t squish all the fluff out. Pop the pan into the oven and bake for 25 to 30 minutes, or until the top turns a gorgeous golden brown and a toothpick inserted near the center comes out mostly clean. Patience here pays off because letting the bars cool completely before slicing ensures clean, beautiful portions.
How to Serve Fluffernutter Bars: An Incredible Ultimate Recipe
Garnishes
Give your bars an extra touch of love by sprinkling some chopped peanuts or a light drizzle of melted peanut butter on top before serving. A pinch of flaky sea salt also amps up the flavors and contrasts beautifully with the sweetness, making every bite utterly addictive.
Side Dishes
These bars pair wonderfully with a cold glass of milk or a hot cup of coffee or tea, depending on your mood. For a more indulgent dessert experience, try serving them alongside vanilla ice cream or fresh berries to balance the richness with fruity brightness.
Creative Ways to Present
For a fun party treat, cut these bars into bite-sized squares and serve them on a platter garnished with whole peanuts or mini marshmallows. You can also sandwich two bars with a scoop of ice cream for a decadent fluffernutter-inspired ice cream sandwich that’s sure to impress guests of all ages.
Make Ahead and Storage
Storing Leftovers
Fluffernutter Bars: An Incredible Ultimate Recipe stay fresh and delicious when stored in an airtight container at room temperature for up to 3 days. If you prefer a slightly firmer texture, refrigerate them for up to a week. Just bring to room temperature before serving to enjoy that perfect chewiness.
Freezing
If you want to keep these bars for longer, freezing is your best friend. Wrap them tightly in plastic wrap and then foil, or place them in a freezer-safe container. They will keep beautifully for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge and then allow to warm up on the counter before diving in.
Reheating
To revive the soft, melty magic of your Fluffernutter Bars, warm them in the microwave for about 15 seconds or in a low oven (around 300°F) for 5 to 10 minutes. This brings back the gooey marshmallow goodness and peanut butter warmth as if they were just freshly baked.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter adds a nice texture contrast and extra peanut flavor. Just keep in mind that the bars may be a bit more textured and less smooth, which many folks actually prefer.
Is it possible to make Fluffernutter Bars gluten-free?
Yes, substituting all-purpose flour with a gluten-free blend designed for baking usually works well. Just make sure it contains xanthan gum or another binder to keep the bars from crumbling.
Can I substitute marshmallow fluff with homemade marshmallow cream?
Definitely! Homemade marshmallow cream or even melted marshmallows can be used as a substitute, but the consistency might differ slightly. The flavor will still be heavenly, so feel free to experiment.
How do I get the bars to have clean edges when cutting?
Make sure the bars are completely cooled, preferably chilled for at least 30 minutes before slicing. Using a sharp knife wiped clean between cuts will help you get neat, professional-looking bars every time.
Can I double the recipe for a larger batch?
Yes! Simply double all the ingredients and bake in a 9×13-inch pan, adjusting the baking time to around 35-40 minutes. Keep an eye on the bars so they don’t overbake.
