Ingredients
For the Cookie Dough
- 1/2 cup unsalted butter, softened
- 1/2 cup creamy peanut butter
- 1/2 cup granulated sugar
- 1/2 cup brown sugar
- 1 egg
- 1 tsp. vanilla
- 1/2 tsp. baking soda

- 1 tsp. cornstarch
- 1 cup all-purpose flour
For the Filling
- 3/4 cup marshmallow cream/fluff
How to Make Fluffernutter Cookies (Peanut Butter and Marshmallow Cream)
Step 1: Prepare the Dry Ingredients
In a medium-size mixing bowl, whisk together the all-purpose flour, salt, cornstarch, baking soda, and baking powder until well combined. Set this mixture aside for later use.
Step 2: Cream the Butters
In a large mixing bowl, beat the softened butter and creamy peanut butter using an electric mixer until smooth and creamy. This step is crucial for achieving a light texture in your cookies.
Step 3: Add Sugars and Egg
To the peanut butter mixture, add granulated sugar, brown sugar, egg, and vanilla extract. Continue beating until everything is smooth and fluffy.
Step 4: Combine Dry Ingredients
Slowly add in the reserved flour mixture while mixing at a low speed until just combined. Be careful not to overmix; we want tender cookies!
Step 5: Chill the Dough
Refrigerate the cookie dough for at least 30 minutes. Chilling helps to solidify the fats in the dough which leads to better texture during baking.
Step 6: Preheat Oven
Once chilled, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
Step 7: Shape Cookies
Using a medium-sized cookie scoop or measuring spoon, scoop out about 2 tablespoons of cookie dough. Flatten it into a disk shape. Place about 1 tablespoon of marshmallow cream/fluff in the center before folding the dough around it to form a ball.
Step 8: Bake
Place the cookie balls onto the prepared baking sheet with enough space between them. Bake in your preheated oven for approximately 10 minutes or until lightly golden at the edges.
Step 9: Cool
Remove from oven and let cool slightly before transferring them to a wire rack to cool completely. Enjoy your delicious Fluffernutter Cookies!

How to Perfect Fluffernutter Cookies (Peanut Butter and Marshmallow Cream)
Perfecting your Fluffernutter Cookies can make all the difference. Here are some tips to ensure they come out delicious every time.
- Chill the Dough: Refrigerating the dough for at least 30 minutes helps prevent spreading during baking, resulting in thicker cookies.
- Use Room Temperature Ingredients: Soften your butter and use room temperature eggs for better mixing and texture.
- Don’t Overmix: Mix until just combined to keep the cookies soft and chewy rather than tough.
- Measure Flour Correctly: Use the spoon-and-level method to measure flour accurately; too much can lead to dry cookies.
- Monitor Baking Time: Keep an eye on the cookies while baking; they should look slightly underbaked when you take them out for optimal gooeyness.
- Store Properly: Store leftover cookies in an airtight container at room temperature to maintain their softness.

Common Mistakes to Avoid
When making Fluffernutter Cookies, it’s easy to make a few common mistakes that can affect the final result. Here are some to watch out for:
- Using cold butter: Cold butter doesn’t mix well with peanut butter, leading to lumpy dough. Always ensure your butter is softened for a smooth blend.
- Not chilling the dough: Skipping the refrigeration step can result in flat cookies. Chilling helps the flavors meld and keeps them thick during baking.
- Overmixing the dough: Mixing too long can make cookies tough. Mix until just combined for soft, chewy Fluffernutter Cookies.
- Incorrect oven temperature: Baking at the wrong temperature can lead to undercooked or burnt cookies. Use an oven thermometer to ensure accuracy.
- Skipping parchment paper: Not lining your baking sheet can cause sticking and uneven baking. Always use parchment paper or a silicone mat for best results.
Refrigerator Storage
- Store Fluffernutter Cookies in an airtight container in the refrigerator.
- They will stay fresh for up to 1 week.
Freezing Fluffernutter Cookies (Peanut Butter and Marshmallow Cream)
- Place cookies in an airtight container or freezer bag.

- For best results, separate layers with parchment paper.
Reheating Fluffernutter Cookies (Peanut Butter and Marshmallow Cream)
- Oven: Preheat to 350°F, place cookies on a baking sheet, and heat for about 5 minutes.
