Fluffernutter Cookies Ingredients
For the Dough
• Unsalted Butter – Adds moisture and flavor; feel free to use salted for a hint of saltiness.
• Creamy Peanut Butter – Provides a rich peanut flavor and structure; natural peanut butter gives a nuttier taste though it may alter texture.
• Granulated Sugar – Sweetens and helps crisp the cookies; coconut sugar can be a softer alternative.
• Light Brown Sugar – Adds moisture and depth; substitute with dark brown sugar for a richer flavor.
• Large Egg – Binds everything together; for a vegan option, swap in a flax egg (1 tbsp flaxseed meal + 3 tbsp water).
• Vanilla Extract – Enhances the overall flavor; pure vanilla extract is best for optimal taste.
• Baking Soda – Acts as a leavening agent; be sure it’s fresh for the best results.
• Salt – Balances sweetness and enhances overall flavor.
• All-Purpose Flour – Provides necessary structure; consider a gluten-free blend if needed.
For the Mix-ins
• Mini Marshmallows – Creates that fluffy, signature Fluffernutter experience; regular marshmallows can be cut down if you don’t have mini ones.
• Semisweet Chocolate Chips – Adds richness; dark chocolate chips can intensify the sweetness.
For the Glaze
• Corn Syrup – Gives a glossy chocolate glaze; light honey can serve as a natural substitute.
• Additional Butter (for glaze) – Enhances the melt-in-mouth texture of the chocolate drizzle.

Step‑by‑Step Instructions for Fluffernutter Cookies
Step 1: Prepare the Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt until they are fully combined. This step ensures that your Fluffernutter Cookies will rise evenly and have the perfect texture. Set the bowl aside while you work on the wet ingredients.
Step 2: Mix Wet Ingredients
In a stand mixer, cream together ½ cup of softened unsalted butter, ½ cup of creamy peanut butter, ¾ cup of granulated sugar, and ½ cup of light brown sugar until the mixture is light and fluffy, about 2 minutes. Add 1 large egg and 1 teaspoon of vanilla extract, mixing until completely combined, achieving a smooth and creamy batter.
Step 3: Combine Mixtures
Gradually add the dry ingredient mixture to the wet mixture in the stand mixer, mixing on low speed until the dough is smooth and just combined. This helps prevent overmixing. Once mixed, cover the bowl with plastic wrap and chill the dough in the refrigerator for 15 minutes to achieve the ideal consistency for shaping.
Step 4: Shape Cookies
While the dough chills, preheat your oven to 350°F (175°C). Roll the chilled dough into 1½-inch balls, placing them onto lined baking sheets about 2 inches apart. Use your thumb to create an indentation in the center of each ball, preparing them for mini marshmallows, which will add that fluffy texture to the Fluffernutter Cookies.
Step 5: Bake
Bake the cookies in the preheated oven for 7-9 minutes, or until they are very lightly browned at the edges. Once done, quickly press the center of each cookie again to maintain its shape and top them with mini marshmallows. Return the baking sheets to the oven for an additional 2-3 minutes until the marshmallows melt, creating a delightful gooey topping.
Step 6: Cool
Remove the baking sheets from the oven and allow the cookies to cool on the sheets for about 5 minutes. This resting period ensures they firm up slightly before transferring them to a wire rack, where they will cool completely. This crucial step keeps the Fluffernutter Cookies from falling apart while hot.
Step 7: Prepare Chocolate Glaze
In a heatproof bowl set over simmering water, melt 1 cup of semisweet chocolate chips, 2 tablespoons of butter, and 2 tablespoons of corn syrup. Stir the mixture with a whisk until smooth and glossy—this chocolate glaze will add a rich finish to your cookies. Once melted, drizzle over the cooled cookies for a delicious chocolatey topping.

Make Ahead Options
These Fluffernutter Cookies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the cookie dough up to 3 days in advance by mixing the wet and dry ingredients, then chilling the dough in the refrigerator until you’re ready to bake. For longer storage, freeze the shaped dough balls for up to 3 months—just make sure to thaw them in the refrigerator overnight before baking. When you’re ready to enjoy the cookies, simply bake them as directed, adding marshmallows and chocolate glaze for that delicious finishing touch. This way, you’ll have fresh, chewy Fluffernutter Cookies anytime you need a sweet treat, all with minimal effort!

Fluffernutter Cookies Recipe FAQs
How do I select the right peanut butter for these cookies?
Absolutely! For the best flavor and texture, I recommend using creamy peanut butter as it provides a rich, nutty taste and helps bind the ingredients together. If you’re looking for a more intense nut flavor, natural peanut butter can be used, but keep in mind that it may alter the cookie’s texture slightly.
What is the best way to store Fluffernutter Cookies?
Very easy! Store your cookies in an airtight container at room temperature for up to 4 days. If you want them to last longer, you can refrigerate them for up to a week, just remember to let them come back to room temperature before enjoying their chewy goodness!
Can I freeze the cookie dough for later use?
The more the merrier! Freezing the unbaked dough is super simple. Just roll the dough into balls, place them on a baking sheet to freeze until solid, then transfer them to a zip-top freezer bag. They can stay in the freezer for up to 3 months. When you’re ready to bake, there’s no need to thaw—just add a couple of extra minutes to the baking time!
What should I do if my cookies spread too much while baking?
Don’t worry! If you find your dough is too sticky or the cookies are spreading too much, try chilling the dough for a bit longer before baking. If they still spread excessively, fold in a little extra flour, about 1 tablespoon at a time, until the dough is easier to handle and holds its shape better during baking.
Are these cookies safe for those with peanut allergies?
Great question! Unfortunately, these Fluffernutter Cookies contain peanut butter, so they’re not suitable for anyone with peanut allergies. You can try substituting almond or sunflower butter instead; however, check for any cross-contamination in your kitchen to be safe for those with severe allergies.
How long can I keep these cookies before they go stale?
You can maintain their deliciousness for up to 4 days at room temperature in an airtight container. However, reheating can bring back some of that fresh-baked taste, so a quick zap in the microwave for about 10-15 seconds will make them feel freshly baked again even after a few days!
