Step-by-Step Instructions
Here’s how to make Fluffernutter Cookies:
Prep the Cookie Dough:
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
- Mix the Ingredients: In a large bowl, combine the peanut butter, sugar, egg, vanilla extract, baking soda, and salt (if using). Mix until smooth and well combined.
Shape the Cookies:
- Form Cookie Dough Balls: Scoop tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheet, leaving about 2 inches of space between each.
- Create a Dimple: Use your thumb to press a small dimple in the center of each dough ball. This will create a spot for the marshmallow fluff.
Add the Marshmallow Fluff:
- Fill with Marshmallow Fluff: Spoon about 1 teaspoon of marshmallow fluff into the center of each cookie, pressing it gently into the dimpled dough.
Bake the Cookies:
- Bake: Place the baking sheet in the oven and bake for 12-15 minutes, or until the cookies are lightly golden around the edges but still soft in the center.
- Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

How to Serve Fluffernutter Cookies
Fluffernutter Cookies can be served in several delightful ways:
- Classic Presentation: Serve the cookies as-is with a glass of milk for a classic treat.
- For a Party: Arrange the cookies on a platter with other bite-sized treats for a fun dessert spread.

Additional Tips for Fluffernutter Cookies
Here are some extra tips to make your Fluffernutter Cookies perfect every time:
- Use Room Temperature Ingredients: Let the peanut butter and egg come to room temperature for smoother mixing.
- Don’t Overbake: These cookies should be soft in the center, so make sure to remove them from the oven when they’re lightly golden around the edges.
- For Extra Crunch: If you prefer more texture, add chopped peanuts or even some mini chocolate chips to the dough.
- Chill the Dough: If you have the time, chilling the cookie dough for 30 minutes before baking can help them keep their shape and prevent spreading.
