How to Make Fluffernutter Cookies
-
Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper, ensuring your delicious cookies won’t stick while baking.
-
Combine peanut butter, unsalted butter, and light brown sugar in a large bowl. Use a hand mixer and blend until the mixture turns smooth and creamy, about 2-3 minutes for that perfect texture.
-
Add the egg and vanilla extract. Mix until everything is well combined, which should take about 30 seconds of mixing. This helps incorporate those sweet flavors.
-
Incorporate the dry ingredients. Add all-purpose flour, cornstarch, and kosher salt. Mix on low speed until just combined, around 30 seconds to 1 minute, to avoid overmixing.
-
Scoop the dough using a 2-tablespoon cookie scoop and drop it onto the lined baking sheets. Flatten each scoop into a 3-inch disk using your hand; this helps the cookies spread evenly while baking.
-
Fill the centers. With two spoons, carefully add about 1 tablespoon of marshmallow fluff to the middle of each cookie disk.
-
Wrap the dough around the marshmallow fluff to enclose it completely, forming a ball. Place the filled dough balls back onto the lined baking sheets, leaving some space in between.
-
Bake the cookies for 10-12 minutes. Watch them closely, ensuring they turn golden brown around the edges without burning the marshmallow fluff!
-
Cool the cookies on the baking sheets for 10-15 minutes before serving. This resting period allows them to firm up and enhances their chewy texture.
Optional: Dust with powdered sugar for a festive touch!

Fluffernutter Cookies Recipe FAQs
How do I choose ripe ingredients for Fluffernutter Cookies?
Absolutely! When selecting ingredients like peanut butter, opt for creamy varieties that have a smooth consistency for easy mixing. The unsalted butter should be at room temperature for optimal blending; you can leave it out for about an hour before baking. Look for light brown sugar that’s freshly packed to ensure moisture, creating that delightful softness.
What’s the best way to store Fluffernutter Cookies?
Very good question! Store your Fluffernutter Cookies in an airtight container at room temperature for up to 3 days. If you’d like them to last longer, the fridge is a great option, keeping them fresh for up to 1 week. Just remember to let them come to room temperature before enjoying them for the best flavor!
Can you freeze Fluffernutter Cookies?
Absolutely! For longer storage, freeze your Fluffernutter Cookies for up to 3 months. Simply wrap each cookie tightly in plastic wrap, and then place them in a freezer-safe bag to prevent freezer burn. When you’re ready to indulge, just thaw them at room temperature or pop them in the microwave for about 10-15 seconds, and enjoy that gooey marshmallow center all over again!
What should I do if my cookies spread too much while baking?
No worries, it happens to the best of us! If your cookies spread too much, it may be due to too much moisture in the butter or flour. Make sure to measure your flour accurately, spooning it into the measuring cup and leveling off the top with a knife. If your dough feels too soft, let it chill in the fridge for 30 minutes before baking to help control the spread.
Are Fluffernutter Cookies safe for pets?
Great question! Since Fluffernutter Cookies contain ingredients like peanut butter and sugar, it’s best to avoid giving them to pets. While plain peanut butter can be safe in moderation, chocolate or high-sugar content can be harmful to them. Always keep your furry friends’ diet in mind!
Can I make these cookies gluten-free?
Very much so! If you’re looking to make gluten-free Fluffernutter Cookies, simply substitute the all-purpose flour with a gluten-free flour blend that has xanthan gum included. This will help maintain the chewy texture. Just be sure to use certified gluten-free ingredients to avoid any cross-contamination!
