Key Ingredients for Fluffernutter Brownies
Creating the perfect Fluffernutter Brownies is all about using the right ingredients. Each component plays a vital role in achieving that gooey, rich, and nutty flavor profile that we all crave.
Butter
Butter is essential in this recipe, providing a luscious richness and helping the brownies maintain that fudgy texture. I use it generously to ensure everything bakes perfectly and adds a delightful flavor to each bite.
Granulated Sugar
Granulated sugar is what gives our Fluffernutter Brownies that delightful sweetness. It also contributes to the crackly top that forms during baking, creating a contrast to the chewy interior.
Brown Sugar
I like to incorporate brown sugar for its deeper flavor and moistness—especially with its hints of molasses, which elevate the richness of brownies to a whole new level.
Eggs
Eggs are vital for binding the ingredients together and providing the structure we desire. I use two to get that perfect fudgy texture, creating a delicious balance between cakey and gooey.
Vanilla Extract
A splash of vanilla extract adds a warm undertone to the Fluffernutter Brownies that complements the sweetness beautifully. It’s a simple yet pivotal ingredient that enhances the overall flavor.
All-Purpose Flour
All-purpose flour helps to give stability to our brownies while keeping them chewy. It’s the backbone of the recipe, ensuring everything stays together as it bakes.
Cocoa Powder
Cocoa powder is what gives our Fluffernutter Brownies that rich chocolate flavor. I opt for unsweetened cocoa to balance out the sweetness from the sugars.
Salt
Adding a pinch of salt enhances all the flavors and elevates the chocolate, providing that perfect contrast to sweetness. It’s crucial, so don’t skip this step!
Creamy Peanut Butter
Creamy peanut butter is where the magic happens. It lends a smooth texture and nutty flavor that makes these brownies unmistakably Fluffernutter. You might even find yourself eating it straight from the jar.
Marshmallow Fluff
Finally, Marshmallow fluff brings that sweet, gooeyness that ties everything together. It creates a dreamy layer that adds a fun twist to the classic brownie, making every bite an indulgent experience.
With these key ingredients in hand, you’re well on your way to creating the ultimate Fluffernutter Brownies!

Cooking Tips and Notes for Fluffernutter Brownies
Creating the perfect batch of fluffernutter brownies is all about the details. Here are some friendly tips to ensure your brownies turn out delicious and indulgent every time.
Achieving the perfect consistency
To get that ideal fudgy texture, make sure not to overmix your batter. Gently fold the ingredients until just combined. The batter should be thick, but not dry, and the chocolate should be melted but not too hot when you combine it with the other ingredients. This will give you a rich, gooey brownie that’s melt-in-your-mouth delicious.
The best pan to use
For the best results, use a metal baking pan. A 9×9-inch pan is perfect, as it promotes even cooking and gives you those crisp edges that contrast beautifully with the soft center. If you prefer, you can line the pan with parchment paper for easy removal, allowing that wonderful brownie goodness to shine when you cut into it.
Storing your brownies
To keep your fluffernutter brownies fresh, store them in an airtight container at room temperature for up to four days. If you want to enjoy them even longer, freeze them in individual portions. Just make sure to wrap each piece tightly to avoid freezer burn, and they’ll be ready for your next sweet craving!

FAQs about Fluffernutter Brownies
Fluffernutter brownies are a delightful blend of chocolatey goodness and marshmallow-peanut butter sweetness that can raise some questions for even the most seasoned bakers. Here’s a helpful guide to address some common queries you might have while whipping up this delectable treat.
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter can add a delightful texture to your fluffernutter brownies. The chunks of peanuts create a fun contrast with the smooth chocolate and gooey marshmallow. Just keep in mind that it may slightly alter the overall consistency, but it will still be deliciously satisfying.
How can I make these brownies more gooey?
To achieve that irresistibly gooey texture in your fluffernutter brownies, there are a couple of tricks. First, underbake the brownies by a few minutes—this allows them to stay soft and fudgy. Second, consider adding an extra layer of marshmallow fluff on top right after baking; it will melt and create a delightful topping that enhances that gooeyness.
Are there any ways to reduce sugar in the recipe?
Reducing sugar in fluffernutter brownies can be a bit tricky since both the marshmallows and peanut butter contribute to the sweetness. However, you can try these alternatives:
- Substitute some granulated sugar with applesauce or mashed bananas to maintain moisture while cutting down on sugar.
- Experiment with a sugar substitute, like erythritol or stevia, but be mindful of the sweetness level, as these can be much sweeter than regular sugar.
By experimenting with these adjustments, you can find a balance that suits your taste while still enjoying the rich flavors of your brownies!
