Fluffernutter Cookies Ingredients For the Cookies • Peanut Butter – Provides the primary flavor and chewy texture; use creamy for smoother cookies or crunchy for added texture. • Sugar – Adds sweetness; feel free to adjust to taste for your ideal balance of sweetness. • Brown Sugar – Contributes moisture and deeper flavor, and can be swapped with coconut sugar for a less sweet option. • Egg – Binds the ingredients and helps them rise; room temperature eggs blend better for a smooth dough. • Baking Soda – Essential for helping cookies rise and achieve that oh-so-soft texture; make sure it’s fresh for best results. • Flour – Gives structure to the cookies; all-purpose flour is typical, but gluten-free blends work too if needed. For the Marshmallow Buttercream • Marshmallow Fluff – The star of the filling, creating a dreamy, sweet layer; store-bought fluff saves time, or you can make your own for a special touch. • Butter – Adds richness and creaminess; use unsalted for better control over the sweetness. • Powdered Sugar – Sweetens the buttercream and gives it a delightful texture; beat thoroughly to eliminate any grittiness. Treat yourself and your loved ones to these scrumptious Fluffernutter Cookies—they are sure to become a favorite in your home! Step‑by‑Step Instructions for Fluffernutter Cookies Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). This temperature is crucial for baking soft and chewy fluffernutter cookies. While you’re waiting for the oven to reach the desired temperature, line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze. Step 2: Mix the Dough In a large mixing bowl, combine creamy peanut butter, granulated sugar, and brown sugar until the mixture is smooth and well-blended. You can use a hand mixer or a sturdy spatula for this step. Add in a room temperature egg and continue mixing until everything is cohesive and creamy, bringing the comforting essence of your fluffernutter cookies to life. Step 3: Add Dry Ingredients Next, add the all-purpose flour and baking soda to your peanut butter mixture. Gently stir until a soft dough forms, ensuring no visible flour remains. The dough should be thick and slightly sticky, exuding the delightful aroma of peanut butter. This step is vital for creating the perfect texture in your cookies, so mix carefully. Step 4: Shape the Cookies Scoop out small portions of dough and roll them into balls about the size of a tablespoon. Place each ball onto the prepared baking sheet, spacing them about two inches apart to allow for spreading while baking. As you shape the cookies, envision the soft, chewy fluffernutter cookies that will soon emerge from the oven! Step 5: Bake the Cookies Slide your baking sheet into the preheated oven and bake the cookies for 10 to 12 minutes. You’re looking for golden edges with a soft center; they will continue to firm up once they cool. Keep an eye on them to avoid overbaking, ensuring they retain their characteristic softness that makes fluffernutter cookies so delightful. Step 6: Prepare the Marshmallow Buttercream While the cookies are cooling, it’s time to make the filling. In a mixing bowl, beat together marshmallow fluff, softened butter, and powdered sugar until it reaches a creamy consistency. This airy, sweet mixture will perfectly complement your fluffy cookies. Mix until the buttercream is smooth and free of lumps for the best texture. Step 7: Assemble the Fluffernutter Cookies Once your cookies have cooled slightly, take one cookie and spread a generous layer of marshmallow buttercream on the flat side. Place another cookie on top, gently pressing them together to create a delightful sandwich. Repeat this process until all cookies are filled, creating a batch of scrumptious fluffernutter cookies ready to be enjoyed! Make Ahead Options These Fluffernutter Cookies are perfect for busy home cooks looking to streamline their baking process! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and storing it in an airtight container in the refrigerator. The marshmallow buttercream can also be made ahead—just keep it covered at room temperature for up to 3 days. When you’re ready to bake, simply scoop and shape the cookies, then bake as directed. This means you can savor fresh, homemade fluffernutter cookies on your schedule, without compromising their soft, chewy texture or delightful flavor! Storage Tips for Fluffernutter Cookies Room Temperature: Store the assembled fluffernutter cookies in an airtight container at room temperature for up to 5 days to keep them fresh and chewy. Refrigerator: For extended freshness, refrigerate the cookies for up to 10 days. Just ensure they are in a sealed container to prevent the cookies from drying out. Freezer: You can also freeze fluffernutter cookies! Layer them between parchment paper in a sealed container or freezer bag for up to 3 months. Thawing: To enjoy frozen cookies, simply remove them from the freezer and let them thaw at room temperature. Reheat in the microwave for a few seconds if you prefer that fresh-baked taste. What to Serve with Fluffernutter Cookies Pairing these delightful treats with complementary flavors and textures can elevate your dessert experience to new heights. Cold Milk: The classic choice; a cold glass of milk balances the sweetness and enhances the peanut butter flavor. Hot Cocoa: This cozy drink makes every bite feel like a warm hug, perfect for chilly nights when indulgence is needed. Chocolate Ice Cream: Rich and creamy, chocolate ice cream adds a decadent touch that beautifully contrasts with the soft cookies. Fresh Berries: Bright, juicy berries such as strawberries or raspberries provide a refreshing tartness to balance the sweetness. Whipped Cream: Light and airy, a dollop of whipped cream can make the cookies feel even more indulgent for special occasions. Coffee: An aromatic coffee pairs well, cutting through the sweetness and enhancing the nutty flavors in every chewy bite. Powdered Sugar Dusting: A sprinkle of powdered sugar adds an elegant touch, making these cookies visually appealing for gatherings. Peanut Butter Cup Dessert Shooters: Layer into small glasses with whipped cream and chocolate sauce for a fun, themed dessert experience. Milkshakes: Blend soft-serve ice cream with milk for a dreamy, complimentary shake, making every bite a decadent journey of flavors. Expert Tips for Fluffernutter Cookies Avoid Over-Baking: Keep an eye on the cookies as they bake; they should be golden around the edges but still soft in the center to maintain the chewy texture of your fluffernutter cookies. Room Temperature Eggs: Always use room temperature eggs in the cookie dough for a smoother consistency, helping everything blend perfectly. Cookie Scoop: Use a cookie scoop to ensure that all your cookies are uniform in size. This way, they will bake evenly and be easier to sandwich together. Thorough Mixing: Beat the marshmallow buttercream until it’s smooth and creamy, preventing any grittiness from powdered sugar, which is essential for a delicious filling. Chill Your Dough: If your dough feels too sticky, chill it in the fridge for about 30 minutes before rolling into balls. This helps achieve the perfect texture when baked. Fluffernutter Cookies Variations & Substitutions Feel free to venture off the beaten path and customize your fluffernutter cookies with these delightful twists! Nut Butter Alternative: Swap peanut butter for almond or cashew butter to explore different flavors while maintaining that beloved creamy texture. Add-In Delights: Mix in chocolate chips or chopped nuts for an added crunch that complements the soft cookies perfectly—think of the delightful surprise in every bite! Coconut Flour: For a gluten-free option, replace all-purpose flour with coconut flour; just use about 1/4 cup, as it absorbs more liquid. Chocolate Drizzle: Drizzle melted chocolate over the assembled cookies for a rich, decadent finish—because sometimes, more chocolate is always better! Flavored Cream: Infuse the buttercream with vanilla, almond, or even peppermint extract for a unique twist that elevates these cookies to a whole new level of deliciousness.

The best peanut butter for these cookies can vary based on your preference. For a smooth texture, opt for creamy peanut butter, which blends seamlessly into the cookie dough. If you enjoy a bit of crunch, go for crunchy peanut butter to add delightful texture. Just make sure that the peanut butter is not overly oily, as it can affect the cookie’s consistency. What is the best way to store fluffernutter cookies? To keep your fluffernutter cookies fresh, store them in an airtight container at room temperature for up to 5 days. This helps retain their chewy texture. For longer storage, place them in the refrigerator for up to 10 days. Always ensure they’re in a sealed container to prevent drying out—trust me, that’s a game changer! Can I freeze fluffernutter cookies? If so, how? Yes, you can absolutely freeze fluffernutter cookies! Here’s how: First, layer the cookies between pieces of parchment paper inside a sealed container or freezer bag. This prevents them from sticking together. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply remove the desired number of cookies and let them thaw at room temperature. For an extra touch of warmth, gently reheat them in the microwave for about 10 seconds. What should I do if my cookies come out too flat or crispy? Very! If your fluffernutter cookies turn out too flat or crispy, it could be due to a few common culprits. First, check that you’re using enough flour—measuring accurately is essential. If you accidentally over-mix the dough after adding flour, it can lead to denser cookies as well. Make sure your baking soda is fresh, as older leavening agents may not provide adequate rise. Lastly, be careful not to over-bake; taking them out when they’re still soft in the center is key! Are there any dietary considerations for fluffernutter cookies? Yes, it’s important to consider dietary restrictions! For nut allergies, you can substitute the peanut butter with sunflower seed butter or another nut-free alternative. If you’re looking for a gluten-free option, use gluten-free all-purpose flour in your cookie dough. Always double-check your marshmallow fluff, as some brands may contain allergens or gluten. These simple swaps ensure everyone can enjoy your delicious fluffernutter cookies! How can I tell when my cookies are done baking? You’ll want to look for visual cues—your cookies should have golden edges and a soft center. They will continue to firm up after being removed from the oven. A good rule of thumb is to bake for 10 to 12 minutes; you can also gently press the tops of the cookies to see if they spring back, indicating they are ready to come out.
