Ingredients You’ll Need
These ingredients are straightforward but essential, each playing a crucial role in balancing the fudgy texture, the sweet and salty flavor profile, and the beautiful rich color of your Fluffernutter Brownies. Having them ready makes the process smooth and fun.
- 1 cup unsalted butter: Melted to provide richness and moisture for that perfect fudgy crumb.
- 1 cup granulated sugar: Adds sweetness while helping create a slight crisp on the brownie edges.
- 1 cup brown sugar: Contributes a deep, caramel-like flavor and extra chewiness.
- 3 large eggs: Bind everything together and give structure to the brownies.
- 2 teaspoons vanilla extract: Infuses warmth and enhances the chocolate and peanut butter notes.
- 1 cup all-purpose flour: The backbone that holds the brownies firm but tender.
- 1 cup unsweetened cocoa powder: Responsible for the intense chocolate flavor and rich dark color.
- 1/2 teaspoon salt: A tiny pinch to balance sweetness and deepen flavor layers.
- 3/4 cup marshmallow fluff: Creates that iconic fluffy sweetness swirling through the batter.
- 3/4 cup creamy peanut butter: Offers that beloved nutty, creamy punch that defines the fluffernutter combo.
- 1/2 cup chocolate chips or chunks (optional): Adds pockets of melty chocolate for extra decadence.
How to Make Fluffernutter Brownies Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C) and lining an 8×8-inch pan with parchment paper. This ensures your brownies won’t stick and makes clean-up effortless.
Step 2: Melt the Butter
Gently melt the unsalted butter in a saucepan or a microwave-safe bowl and let it cool slightly so it’s warm, not hot. This step is key for blending smoothly with the sugars without scrambling your eggs later.
Step 3: Mix in the Sugars
Whisk the granulated and brown sugars into the melted butter until the mixture is smooth and glossy. This creates a perfect base that’s both sweet and sticky for the brownie batter.
Step 4: Add Eggs and Vanilla
Incorporate the eggs one at a time along with the vanilla extract, mixing until the batter looks glossy and a bit thick. This gives your brownies a tender, tender crumb with a touch of rich flavor.
Step 5: Combine Dry Ingredients
Gently stir in your sifted cocoa powder, flour, and salt. Mix until just combined — overmixing here can lead to tough brownies, so be delicate.
Step 6: Layer the Batter and Swirls
Pour half of the brownie batter into your prepared pan, spreading it evenly. Then, dollop spoonfuls of peanut butter and marshmallow fluff across the surface. Take a knife or skewer and swirl the peanut butter and fluff into the batter carefully to create those beautiful marbled patterns.
Step 7: Add More Batter and Repeat Swirling
Pour the remaining batter over your swirls, smoothing gently, and if you’re feeling indulgent, add more peanut butter and fluff dollops on top to swirl once more. This layering ensures every bite has that perfect bite of fluffernutter magic.
Step 8: Bake to Perfection
Bake your brownies for 28 to 32 minutes. You’ll know they’re ready when a toothpick inserted comes out with a few moist crumbs clinging to it but no wet batter. Let them cool completely before slicing for the cleanest cuts.
How to Serve Fluffernutter Brownies Recipe
Garnishes
A simple dusting of powdered sugar or a sprinkle of mini marshmallows complements the gooey marbled swirls beautifully. For an extra decadent touch, drizzle melted chocolate or peanut butter over the warm brownies right before serving.
Side Dishes
Fluffernutter brownies are wonderfully rich, so pairing them with a scoop of vanilla ice cream or a dollop of whipped cream balances the sweetness and adds a cool creaminess to each bite. Fresh berries or sliced bananas also add a refreshing contrast.
Creative Ways to Present
For parties or special occasions, serve the brownies on a rustic board alongside small bowls of marshmallow fluff and peanut butter for guests to add extra swirls themselves. Alternatively, cut into bite-sized squares and stack them like little towers for a charming dessert display.
Make Ahead and Storage
Storing Leftovers
Once cooled, store your Fluffernutter Brownies in an airtight container at room temperature. They’ll stay moist and fresh for up to 4 days, perfect for satisfying midweek cravings or sharing with friends.
Freezing
Fluffernutter Brownies freeze beautifully. Wrap individual pieces tightly in plastic wrap and place them in a freezer bag. They can be kept frozen for up to 3 months without losing any of that luscious texture or flavor.
Reheating
To enjoy thawed brownies warm, microwave them for 10 to 15 seconds or gently heat in an oven at 300°F for about 5 minutes. This brings back that freshly baked gooeyness, making each bite feel brand-new.
FAQs
Can I use crunchy peanut butter instead of creamy in this Fluffernutter Brownies Recipe?
You can, but creamy peanut butter melts and swirls more smoothly in the batter, creating the signature marbled look and texture. Crunchy peanut butter will add texture but may not swirl as evenly.
Is it necessary to add marshmallow fluff, or can I substitute it?
Marshmallow fluff is essential for achieving the classic fluffernutter taste and texture. However, if you can’t find it, you can use mini marshmallows melted down carefully, although the consistency may differ slightly.
Can I make these brownies gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend suited for baking. Keep in mind, textures can vary, so opt for one that contains xanthan gum or similar binding agents.
What’s the best way to cut the brownies to keep the swirl pattern intact?
Wait until the brownies have completely cooled, then use a sharp, clean knife. Wiping the knife clean between cuts helps keep the edges neat and the swirls visually appealing.
Can I double this Fluffernutter Brownies Recipe for a larger batch?
Yes, doubling the ingredients and using a larger pan will work well. Just watch your baking time—it may need a few extra minutes to cook through. Begin checking at the original bake time and adjust as needed.
Final Thoughts
There’s something truly special about the way peanut butter and marshmallow fluff come together in this Fluffernutter Brownies Recipe to create an irresistibly rich, gooey dessert bursting with nostalgia and warmth. I encourage you to give this recipe a try—you might just discover a new favorite that becomes your go-to treat for any sweet craving or gathering. Happy baking!
