FAQs
Can I use chunky peanut butter instead of creamy?
Yes, chunky peanut butter can be used, but it will add a bit of texture to the cookies. The cookies may be slightly less smooth but will still taste delicious.
What if I don’t have marshmallow fluff?
If marshmallow fluff is unavailable, you can substitute with an equal amount of mini marshmallows, folded into the dough, but the texture will be a bit different.

- 1 cup marshmallow fluff
Dry Ingredients
- 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 right temperature by the time the dough is ready.
- Mix Wet Ingredients: In a large bowl, mix together the peanut butter, granulated sugar, and brown sugar until the mixture is smooth and creamy.

- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt ensuring they’re well incorporated.
- Incorporate Dry into Wet: Gradually add the dry mixture into the wet ingredients, stirring until just combined to avoid overmixing which could toughen the cookies.
- Fold in Marshmallow Fluff: Gently fold the marshmallow fluff into the dough, maintaining its fluffy texture and distributing it evenly without deflating.
- Prepare Baking Sheet: Line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
- Shape Cookies: Drop spoonfuls of the cookie dough onto the prepared baking sheet, spacing them adequately to allow for spreading during baking.
- Bake: Bake the cookies in the preheated oven for 10-12 minutes or until the edges turn lightly golden, indicating they are cooked but still soft inside.

Notes
- For chewier cookies, you can chill the dough for 30 minutes before baking.
- If you prefer a less sweet cookie, reduce granulated sugar to 3/4 cup.
- Use creamy peanut butter for the best texture; chunky will change the cookie consistency.

- Store cookies in an airtight container at room temperature for up to 5 days.
