Tips & Variations
- For extra gooey centers, add an additional tablespoon of marshmallow fluff into the center of each cookie dough ball before baking.
- Swap creamy peanut butter for natural peanut butter for a more intense peanut flavor, but reduce added salt if using salted peanut butter.
- Try mixing in chocolate chips or chopped peanuts for added texture and flavor.
Storage
Store cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies in a sealed container for up to 3 months. To reheat, warm gently in the microwave for 10-15 seconds to restore softness.

FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, crunchy peanut butter will work and add a bit of texture to the cookies, but the dough may be slightly more crumbly.
What if I don’t have marshmallow fluff?
You can substitute with an equal amount of mini marshmallows, folding them into the dough just before baking, though the texture will differ slightly.

Ingredients
Wet Ingredients
- 1 cup creamy peanut butter
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup marshmallow fluff
Dry Ingredients
- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the correct temperature for baking the cookies evenly.
- Mix Peanut Butter and Sugars: In a large bowl, combine the creamy peanut butter, granulated sugar, and packed brown sugar. Stir until the mixture is smooth and creamy.
- Add Eggs and Vanilla: Crack in the eggs and pour in the vanilla extract. Mix thoroughly until all ingredients are well incorporated.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute the leavening and seasoning.
- Mix Dry with Wet: Gradually add the dry flour mixture into the wet peanut butter mixture. Stir gently until just combined to avoid overmixing which can make the cookies tough.
- Fold in Marshmallow Fluff: Gently fold the marshmallow fluff into the cookie dough, ensuring it is evenly distributed without deflating the fluff too much.
- Portion Dough: Drop spoonfuls of dough onto a baking sheet lined with parchment paper, spacing them sufficiently to allow for spreading.
- Bake: Bake the cookies for 10-12 minutes, or until the edges start to turn a light golden color, indicating they are fully baked but still soft inside.
- Cool: Allow the cookies to cool on the baking sheet for a few minutes to set before transferring them to a wire rack to cool completely, ensuring they maintain their chewy texture.
Notes
- Do not overbake the cookies; remove them as soon as edges turn golden to preserve softness.
- Using parchment paper prevents sticking and makes cleanup easier.
- For a nuttier flavor, use natural peanut butter, but note the texture may vary.
- These cookies can be stored in an airtight container for up to 5 days to maintain freshness.
- If you prefer a more pronounced marshmallow flavor, lightly swirl extra marshmallow fluff on top before baking.
