Ultimate Fluffernutter Cupcakes: A Peanut Butter & Marshmallow Dream
Have you ever experienced the magic of a Fluffernutter sandwich? For those unfamiliar, it’s a classic East Coast delight made simply with peanut butter and marshmallow fluff spread between two slices of bread. The combination is surprisingly addictive – sweet, savory, and incredibly comforting. I first encountered this iconic duo during my corporate days when my Vice President, a proud East Coast native, introduced our team to it. He brought in all the ingredients for a staff meeting, and we all had our first taste. I must admit, I was skeptical at first, but one bite changed everything! The blend of flavors was unexpectedly good, creating a truly unique and satisfying experience. Transforming this beloved sandwich into a cupcake was a natural next step, and the results are simply divine.
These Fluffernutter Cupcakes capture all the charm of the original sandwich in a soft, fluffy dessert. Each bite offers a perfect balance of salty peanut butter and sugary marshmallow, baked into a moist cupcake and topped with a luxurious, creamy frosting. They are perfect for birthdays, potlucks, or simply as a special weekend treat. Whether you’re a long-time Fluffernutter enthusiast or new to this flavor pairing, prepare to be amazed by how incredibly delicious these cupcakes are.
The History and Charm of the Fluffernutter
Before we dive into baking, let’s appreciate the simple brilliance of the Fluffernutter. This iconic sandwich, particularly popular in New England, has been a lunchbox staple and a nostalgic comfort food for generations. Its origin traces back to the early 20th century, with the introduction of marshmallow fluff, specifically “Marshmallow Fluff,” which was first sold in 1917 in Somerville, Massachusetts. The combination with peanut butter quickly gained traction, and by the 1960s, it was a household name. The appeal lies in its straightforward yet deeply satisfying flavor profile: the rich, nutty notes of peanut butter perfectly complement the sugary, airy texture of marshmallow fluff.
What makes the Fluffernutter so special is its ability to evoke a sense of childhood wonder. It’s a reminder of simpler times, of quick and easy snacks that brought immense joy. Translating this beloved sandwich into a cupcake format allows us to elevate those comforting flavors into an elegant, yet still fun, dessert. The challenge was to ensure that the distinct taste of both peanut butter and marshmallow shine through in every component of the cupcake – from the batter to the frosting – creating a harmonious and utterly delightful experience for your taste buds.
Baking Perfection: Tips for Your Fluffernutter Cupcakes
Achieving the perfect cupcake isn’t just about following the recipe; it’s also about understanding the nuances of baking. Here are some essential tips to ensure your Fluffernutter Cupcakes turn out incredibly moist, flavorful, and beautifully presented:
- Room Temperature Ingredients: This is a golden rule for baking! Ensure your butter, peanut butter, and eggs are at room temperature. This allows them to cream together more smoothly, creating an emulsified batter that traps air, leading to a lighter, fluffier cupcake texture.
- Measure Accurately: Baking is a science, and precise measurements are crucial. Especially for flour, spoon it into your measuring cup and level it off with a straight edge rather than scooping directly from the bag, which can compact the flour and result in a dense cupcake.
- Don’t Overmix: Once you add the dry ingredients to the wet, mix only until just combined. Overmixing develops the gluten in the flour, leading to tough, chewy cupcakes instead of tender ones. A few small lumps are perfectly fine.
- Fill Cupcake Liners Properly: For uniform cupcakes, fill your liners about two-thirds to three-quarters full. This allows enough room for the cupcakes to rise without overflowing, ensuring an even dome top perfect for frosting.
- Test for Doneness: Ovens can vary. Always use the toothpick test. Insert a toothpick into the center of a cupcake; if it comes out clean or with a few moist crumbs, they’re ready. If it comes out wet, bake for a few more minutes.
- Cool Completely: It’s tempting to frost warm cupcakes, but resist! Frosting on warm cupcakes will melt and slide off. Allow your cupcakes to cool completely on a wire rack before even thinking about adding that delicious frosting.

Ingredients
For the Cupcakes:
- 3 C All-Purpose Flour
- 2 ½ Teaspoons Baking Powder
- ½ C Soft Unsalted Butter (room temperature)
- 1 C Creamy Peanut Butter
- 2 C Granulated Sugar
- 4 Large Eggs (room temperature)
- 4 Teaspoons Vanilla Extract
- ⅔ C Whole Milk
- 1 ⅓ C Marshmallow Fluff
For the Frosting:
- 1 C Soft Unsalted Butter (room temperature)
- 1 ½ C Powdered Sugar (or more, to taste/consistency)
- 1 C Marshmallow Fluff
- 1 Teaspoon Vanilla Extract
- 1 C Creamy Peanut Butter (slightly runny for drizzling)
Instructions
For the Cupcakes:
- Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper cupcake liners.
- In a medium bowl, whisk together the dry ingredients: flour and baking powder. Set aside.
- In a large mixing bowl, using an electric mixer, cream together the softened unsalted butter and creamy peanut butter until the mixture is smooth, light, and creamy. This should take about 2-3 minutes.
- Gradually add the granulated sugar to the butter mixture, beating well until light and fluffy. This process incorporates air, contributing to a tender crumb.
- Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next. Scrape down the sides of the bowl as needed.
- Stir in the vanilla extract until just combined.
- With the mixer on low speed, add half of the dry ingredients to the wet mixture. Mix until just combined, being careful not to overmix.
- Pour in the whole milk and continue to mix on low speed until combined.
- Add the remaining half of the dry ingredients to the batter and mix until just incorporated.
- Gently fold in the marshmallow fluff until it’s evenly distributed throughout the batter. Mix just enough to combine.
- Using a large spoon or an ice cream scoop, fill the lined cupcake tins approximately three-quarters full.
- Bake for 20-25 minutes, or until an inserted toothpick comes out clean.
- Allow the cupcakes to cool in the muffin tin for 10-15 minutes before carefully transferring them to a wire rack to cool completely.
For the Frosting:
- In a large mixing bowl, cream the softened unsalted butter with an electric mixer until light and fluffy.
- Gradually add the powdered sugar, mixing on low speed until combined, then increase speed to medium and beat until smooth.
- Stir in the vanilla extract and mix well.
- Add the marshmallow fluff to the mixture. Beat on medium-high speed for several minutes.
- Continue beating until the frosting forms and holds stiff peaks. This may take a few minutes, so be patient! If the frosting is too soft, add more powdered sugar a tablespoon at a time until the desired consistency is reached.
- Once the cupcakes are completely cool, scoop the frosting into a pastry bag fitted with a large tip (such as a star tip or round tip).
- Twist the open end of the pastry bag to push the frosting towards the tip, then pipe generous swirls onto each cooled cupcake.
- For an extra touch, gently melt 1 cup of creamy peanut butter in the microwave until slightly runny (about 30 seconds). Drizzle this melted peanut butter artistically over the frosted cupcakes.
Serving and Storage Suggestions
These Fluffernutter Cupcakes are best enjoyed fresh, but they also store well, allowing you to savor them over a few days. For optimal freshness, store them in an airtight container at room temperature for up to 2-3 days. If you need to keep them longer, they can be refrigerated for up to a week. Just remember to bring them back to room temperature before serving for the best flavor and texture, as refrigeration can sometimes alter the texture of both the cake and the frosting.
For an extra special presentation, consider garnishing your finished cupcakes with a few mini marshmallows, a sprinkle of chopped peanuts, or even a light dusting of cocoa powder. They pair wonderfully with a cold glass of milk, a cup of coffee, or even a scoop of vanilla ice cream for an indulgent dessert experience.
Essential Baking Tools and Safety Tip
Having the right tools can make all the difference in your baking journey. For this recipe, a sturdy electric mixer is key for achieving that light and fluffy batter and frosting. Good quality cupcake liners prevent sticking and make for easy serving. And speaking of safety in the kitchen:
Heat-resistant potholders are a must-have in any kitchen. A couple of years ago, we had a fire scare when we accidentally turned on a burner and a cloth potholder caught fire. Thankfully, we quickly noticed the smoke and were able to extinguish it ourselves. Since then, we’ve switched exclusively to heat-resistant silicone potholders, and we highly recommend them for their safety and durability.
