Directions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a bowl, beat together the butter, peanut butter, brown sugar, and granulated sugar until creamy and well combined.
Mix in the egg and vanilla extract until smooth.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients and mix until just combined.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Dollop a small amount of marshmallow fluff on top of each cookie dough ball.
Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
Let the cookies cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely.
