Key Ingredients
Before diving into the baking fun, let’s gather the essentials that make these cookies irresistibly chewy and gooey:
- 1 cup unsalted butter, softened: Provides richness and helps achieve that tender, chewy texture.
- 1 cup granulated sugar: Contributes sweetness and promotes crisp, caramelized edges.
- 1 cup packed brown sugar: Adds moisture and a deep, molasses-like flavor for extra chewiness.
- 1 cup creamy peanut butter: Delivers classic, nutty flavor and binds the dough.
- 2 large eggs: Provide structure and help create a soft, cake-like interior.
- 2 teaspoons vanilla extract: Enhances overall flavor with warm, aromatic notes.
- 3 cups all-purpose flour: Forms the base of the dough and gives cookies their shape.
- 1 teaspoon baking soda: Acts as a leavening agent to lift and lighten the cookies.
- 1/2 teaspoon baking powder: Adds extra lift for a soft, pillowy center.
- 1/2 teaspoon salt: Balances sweetness and enhances peanut butter flavor.
- 1 cup marshmallow fluff: Creates signature gooey swirls and cloudlike pockets in each cookie.
How To Make Baked Chewy Fluffernutter Cookies
Baking these Baked Chewy Fluffernutter Cookies is all about layering creamy peanut butter dough with pillowy marshmallow fluff and achieving just the right bake time for that wonderful contrast between crisp edges and soft centers. Follow these detailed steps to whip up a batch that’s golden, chewy, and studded with sticky marshmallow swirls:
1. Preheat the oven to 350°F and line a baking sheet with parchment paper to ensure even baking and easy cleanup.
2. In a large bowl, cream the softened butter, granulated sugar, packed brown sugar, and peanut butter together on medium speed for 2–3 minutes until light and fluffy.
3. Beat in the eggs one at a time, mixing well after each addition, then stir in the vanilla extract until the mixture is smooth and homogeneous.
4. In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt to evenly distribute the leavening agents.
5. Gradually add the dry ingredients to the wet mixture in two or three additions, mixing on low speed or folding by hand until just combined—avoid overmixing.
6. Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing each ball about 2 inches apart to allow for spreading.
7. Gently flatten each dough ball with the back of a spoon or your fingertips, then place about a teaspoon of marshmallow fluff on top of each cookie.
8. Use a toothpick to lightly swirl the marshmallow fluff into the surface of each cookie, creating pretty, cloudlike patterns without letting the fluff drift off.
9. Bake for 10 to 12 minutes, or until the edges turn a light golden brown while the centers remain soft and slightly underbaked for that signature chew.
10. Allow cookies to cool on the baking sheet for 5 minutes—this helps them set—then transfer to a wire rack to cool completely and preserve their chewy texture.
Serving Suggestions
Once your Baked Chewy Fluffernutter Cookies are baked to perfection, here are a few fun ways to enjoy them:
- Enjoy slightly warm by microwaving a cookie for 5–7 seconds so the marshmallow fluff is extra melty and oozy.
- Pair with an ice-cold glass of milk to balance the rich peanut butter and sweet marshmallow flavors.
- Create a cookie sandwich by spreading extra marshmallow fluff between two cookies for an indulgent treat.
- Package them in gift jars layered with wax paper, tied with a ribbon, and share homemade joy with friends and family.
Tips For Perfect Baked Chewy Fluffernutter Cookies

How To Store It
Proper storage keeps your cookies tasting freshly baked and perfectly chewy. Here’s how to preserve their flavor and texture:
- Room-temperature: Store completely cooled cookies in an airtight container for up to four days to maintain tenderness.
- Refrigeration: Seal in a container and refrigerate for up to one week; bring to room temperature before serving for soft centers.

- Portioning: Individually wrap cookies in plastic wrap or foil before freezing so you can thaw a few treats at a time.
Frequently Asked Questions
Here are some quick answers to common questions about these Fluffernutter cookies:
- How long does it take to prepare and bake these cookies?
Preparation takes about 15 minutes, which includes creaming the butter, sugars, and peanut butter, mixing in the eggs, whisking the dry ingredients, scooping dough, and topping with marshmallow fluff. Baking requires 10 to 12 minutes, followed by a 5-minute rest on the baking sheet before transferring to a wire rack—about 30 to 35 minutes total.
- How can I achieve extra chewiness in these cookies?
For maximum chewiness, reduce the baking time by one minute so the centers stay softer. Using packed brown sugar adds moisture, and be careful not to overbake—remove the cookies as soon as the edges turn lightly golden while the centers remain soft.
- Can I use crunchy peanut butter instead of creamy?
Yes. Swapping in crunchy peanut butter gives the cookies added texture without changing the overall flavor. Just make sure the peanut butter is well softened so it creams smoothly with the butter and sugars.
- What’s the best way to swirl in the marshmallow fluff without making a mess?
After gently flattening each dough ball, place about a teaspoon of marshmallow fluff on top. Use a clean toothpick to lightly swirl the fluff into the dough in a circular motion, working slowly to keep the fluff from spreading off the cookie.
- How should I store leftover cookies, and how long will they stay fresh?
Once completely cool, store cookies in an airtight container at room temperature for up to four days. For longer storage, layer cookies between sheets of wax paper in a freezer-safe container and freeze for up to two months.
- Why are the edges golden while the centers stay soft?
The recipe is designed to yield cookies with slightly crisp edges and tender centers. The high sugar content browns the edges faster, and the recommended bake time ensures the middle doesn’t overcook. Removing cookies as soon as the edges are lightly golden preserves that soft center.
