These Fluffernutter Cookies are soft, chewy, and just a little sticky from the marshmallow fluff. The peanut butter brings a toasted, nutty depth while chocolate chips add occasional pockets of rich sweetness. They smell warm and buttery as they bake, with a golden brown edge and a tender center that pulls apart with a slight stretch of marshmallow.
If you like sweet-and-salty cookie combos, try them alongside a spiced treat such as apple cider cookies for a fun variety at cookie swaps or holiday trays.

How to Make Fluffernutter Cookies
This recipe uses simple steps: cream butter and sugars, add eggs and vanilla, fold dry ingredients, stir in peanut butter, then gently fold in marshmallow fluff and chocolate chips. Drop dough by rounded tablespoons and bake until just golden at the edges. No chilling required unless you want thicker cookies.
Ingredients:
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup creamy peanut butter
- 1 cup marshmallow fluff
- 1 cup chocolate chips
Directions:
Step 1: Preparation
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or use a nonstick baking mat. Set aside and measure ingredients so everything is ready to go.
Step 2: Mixing
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until smooth and fluffy. Beat in the eggs one at a time, then stir in the vanilla. In another bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the creamed mixture, mixing until just combined. Stir in the creamy peanut butter until well blended. Gently fold in the marshmallow fluff and chocolate chips; small streaks of fluff are fine and give the cookies their gooey pockets.
Step 3: Baking
Drop dough by rounded tablespoons onto ungreased or lined baking sheets, spacing them about 2 inches apart. Bake for 10–12 minutes, or until the edges turn light golden brown and the centers look set but still soft.
Step 4: Finishing
Allow the cookies to cool on the baking sheets for 3–5 minutes so they firm up slightly. Then transfer them to a wire rack to cool completely. The marshmallow will settle into the cookie as it cools, leaving gooey, chewy spots.
How to Serve Fluffernutter Cookies
Serve warm for that melty marshmallow and chocolate experience. They pair nicely with cold milk, coffee, or hot chocolate. For a party, arrange on a platter with other cookies, or stack with wax paper between layers for easy grabbing. For a dessert plate, add a scoop of vanilla ice cream and a drizzle of chocolate sauce.
How to Store Fluffernutter Cookies
- At room temperature: Store in an airtight container for up to 3 days. Place a sheet of parchment between layers to prevent sticking.
- In the refrigerator: Keep in an airtight container for up to 1 week; cookies may firm up—bring to room temperature before serving for softer texture.
- Freezing: Freeze baked cookies in a single layer on a baking sheet until solid, then transfer to a freezer bag for up to 3 months. Thaw at room temperature. You can also freeze raw dough scoops (on a tray, then bag) for up to 3 months; bake from frozen, adding 2–3 minutes to the bake time.
Expert Tips for Perfect Fluffernutter Cookies
- Soften butter to room temperature for smooth creaming; it helps trap air and gives a tender texture.
- Don’t overmix once you add flour — overworking develops gluten and can make cookies tough.
- Fold the marshmallow fluff in gently. A few visible streaks are normal and create gooey pockets after baking.
- If your dough is very sticky, chill 15–20 minutes for easier scooping.
- Use creamy peanut butter for a smooth texture; natural peanut butter with oil separation can change the dough consistency.
- For even baking, rotate the baking sheet halfway through the bake time if your oven has hot spots.
Delicious Variations
- Chocolate-Peanut Fluffernutter: Use all chocolate chips or chunks and swirl in extra chocolate for a richer cookie.
- Nut-Free Version: Substitute sunflower seed butter for peanut butter and use allergy-safe chips.
- Salted Caramel Twist: Drop a small caramel candy into each scoop before baking and sprinkle with flaky sea salt when warm.
- Mini Fluffernutter Sandwiches: Bake smaller cookies and sandwich two together with extra marshmallow fluff.
- Crunchy PB: Use crunchy peanut butter or add chopped roasted peanuts for texture.
Frequently Asked Questions
Q: My marshmallow fluff melted into the dough. Is that a problem?
A: A little melting is fine. Marshmallow will blend into pockets and create chewiness. If it fully dissolves, you may not see streaks but the flavor remains. To keep more visible pockets, fold in the fluff at the end and use chilled fluff.
Q: Can I use natural peanut butter?
A: You can, but natural peanut butter often has thinner texture and more oil. Chill it briefly and stir well before measuring. You may need a slightly firmer dough—consider chilling the dough 15 minutes before baking.
Q: How do I stop cookies from spreading too much?
A: Make sure your butter isn’t too soft or melted. Chill the dough for 15–30 minutes before baking to reduce spread. Also avoid over-greasing the baking sheet — parchment is best.
Q: Can I make these gluten-free?
A: Yes. Substitute a 1:1 gluten-free baking flour blend that includes xanthan gum. Texture may vary slightly, but the cookies should remain soft and chewy.
Q: How do I store leftover dough?
A: Scoop dough onto a tray and freeze until firm, then transfer to a freezer bag for up to 3 months. Bake from frozen; add 2–3 minutes to bake time.
Q: Will chocolate chips sink or burn?
A: Chocolate chips generally hold up fine. Use good-quality chips and fold them in gently. If you worry about burning, bake until the edges are just golden and remove promptly.
Q: Can I make the cookies larger or smaller?
A: Yes. Smaller cookies will bake faster (8–10 minutes), larger cookies may need 12–15 minutes. Adjust time and test one batch first.
