Ingredients Breakdown

Yield

24 cookies

Dry Ingredients

• 2 ¼ cups all-purpose flour
• 1 teaspoon baking soda

Wet Ingredients

• ¾ cup unsalted butter, softened
• ¾ cup creamy peanut butter
• ¾ cup light brown sugar, packed
• ½ cup granulated sugar
• 2 large eggs
• 2 teaspoons vanilla extract

Softened butter and creamy peanut butter create a rich, flavorful base with a smooth consistency. Brown sugar adds moisture and chewiness, while granulated sugar helps create lightly crisp edges.

• 1 cup peanut butter chips
• 1 cup mini marshmallows or marshmallow fluff

• Flaky sea salt for garnish (optional)

Peanut butter chips intensify the nutty sweetness while marshmallow fluff or mini marshmallows create gooey pockets throughout the cookies. Extra chips on top give the cookies a bakery-style finish.

Tools & Equipment Needed

To make these Soft and Chewy Fluffernutter Cookies successfully, gather the following kitchen tools:

Essential Equipment

• Large mixing bowl
• Medium mixing bowl
• Electric hand mixer or stand mixer
• Measuring cups
• Measuring spoons
• Rubber spatula
• Whisk
• Baking sheets
• Parchment paper
• Cookie scoop or spoon
• Wire cooling rack

Optional Helpful Tools

• Kitchen scale for precise measuring
• Offset spatula for handling marshmallow fluff
• Silicone baking mats
• Cooling rack with multiple tiers for batch baking

Step-by-Step Instructions

1. Preheat the Oven

Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper. Preparing the baking sheets ahead of time helps ensure even baking and easy cleanup.

2. Mix the Dry Ingredients

In a medium bowl, whisk together:

• 2 ¼ cups all-purpose flour
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ½ teaspoon salt
• 1 tablespoon cornstarch

Whisk until everything is evenly combined and no streaks remain.

3. Cream the Butter and Sugars

In a large mixing bowl, beat together:

• ¾ cup unsalted butter, softened
• ¾ cup creamy peanut butter
• ¾ cup light brown sugar, packed
• ½ cup granulated sugar

Mix until the texture becomes light, fluffy, and creamy. Proper creaming creates a softer cookie texture.

4. Add Eggs and Vanilla

Add the 2 large eggs one at a time, mixing well after each addition. Stir in the 2 teaspoons vanilla extract until fully incorporated.

The dough should appear smooth and glossy at this stage.

5. Combine Wet and Dry Ingredients

Gradually mix the dry ingredients into the wet ingredients until just combined.

Avoid overmixing the dough once the flour is added. Overmixing can create dense cookies instead of soft and chewy centers.

6. Fold in Peanut Butter Chips and Marshmallow

Fold in:

• 1 cup peanut butter chips
• 1 cup mini marshmallows or marshmallow fluff

Gently swirl the marshmallow throughout the dough without overmixing so you maintain visible ribbons and gooey pockets.

7. Chill the Dough

Cover and chill the dough for at least 30 minutes for thicker cookies.

This step helps control spreading during baking and enhances the chewy texture.

8. Scoop the Dough

Scoop the dough onto the prepared baking sheets, spacing the cookies about 2 inches apart.

The dough portions should be evenly sized for consistent baking.

9. Add Toppings

Press extra peanut butter chips onto the tops of the cookies for a bakery-style presentation.

If desired, prepare flaky sea salt for garnishing after baking.

10. Bake

Bake for 10 to 13 minutes until the edges are lightly golden and the centers remain soft.

Do not overbake. The centers should still appear slightly underdone when removed from the oven.

11. Cool the Cookies

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.

This resting period allows the cookies to finish setting while staying soft and chewy.

12. Serve and Store

Serve warm for the ultimate gooey texture or store in an airtight container once completely cooled.

Optional flaky sea salt can be sprinkled on top for extra contrast and flavor.

For a slightly deeper flavor profile, a pinch of cinnamon can complement the peanut butter beautifully without overpowering the recipe.

Flavor Profile

These Soft and Chewy Fluffernutter Cookies are rich, nutty, sweet, and wonderfully nostalgic. The peanut butter creates a creamy, slightly salty depth that balances the sweetness of the marshmallow swirls and peanut butter chips.

The texture is what truly makes these cookies memorable. The edges become lightly golden and delicate while the centers stay thick, soft, and chewy. Marshmallow fluff creates gooey ribbons throughout the cookies, adding stretch and softness to every bite.

Ingredient Spotlight

Peanut Butter

Creamy peanut butter is the heart of these Soft and Chewy Fluffernutter Cookies. It creates rich flavor, tender texture, and deep nuttiness throughout the dough.

When selecting peanut butter, choose a creamy variety with smooth consistency for the best dough texture. Properly stored peanut butter helps maintain freshness and flavor intensity.

Marshmallow Fluff or Mini Marshmallows

The marshmallow component gives these cookies their signature fluffernutter identity. Marshmallow fluff creates silky ribbons while mini marshmallows form gooey pockets throughout the baked cookies.

For maximum gooey texture, gently swirl the marshmallow into the dough instead of fully mixing it in.

Pro Cooking Tips

Use Softened Butter Properly

Butter should be softened but not melted. Properly softened butter creams more effectively with the sugars for lighter texture.

Avoid Overmixing

Once the flour mixture is added, mix only until combined to maintain soft, tender cookies.

Don’t Skip Chilling

The chilling step is key for thick bakery-style cookies with chewy centers.

Underbake Slightly

Remove the cookies when the centers still look soft. Residual heat finishes the baking process without drying them out.

Space Cookies Evenly

Keeping about 2 inches between cookies allows proper airflow and even baking.

Garnish Strategically

Adding extra peanut butter chips on top before baking gives the cookies a professional bakery-style appearance.

Storage & Freezing Guide

Room Temperature Storage

Store completely cooled cookies in an airtight container to preserve softness and chewiness.

Refrigerator Storage

The dough can be refrigerated before baking while covered tightly.

Freezer Storage

Freeze portioned cookie dough or fully baked cookies in freezer-safe containers.

Reheating Instructions

Warm baked cookies briefly before serving to restore their gooey marshmallow texture and soft centers.

What Not to Freeze

Avoid freezing cookies while still warm, as condensation can affect texture.
