Ingredients
2 1/4 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
3/4 cup unsalted butter, softened
1/2 cup granulated sugar
3/4 cup brown sugar
3/4 cup creamy peanut butter
2 large eggs
2 teaspoons vanilla extract
1 cup peanut butter chips
1 cup mini marshmallows
1/2 cup marshmallow fluff
Flaky sea salt for topping (optional)
Instructions
1. Preheat the oven to 350°F and line baking sheets with parchment paper.
2. Whisk together the flour, baking soda, and salt in a medium bowl.
3. Beat the butter, granulated sugar, brown sugar, and peanut butter until light and creamy.
4. Add the eggs one at a time, then mix in the vanilla extract.
5. Gradually add the dry ingredients and mix until just combined.
6. Fold in the peanut butter chips and mini marshmallows gently.
7. Scoop the dough onto prepared baking sheets with spacing between each cookie.
8. Add spoonfuls of marshmallow fluff on top of each cookie dough ball.
9. Bake for 10 to 12 minutes until the edges are lightly golden.
10. Cool the cookies on the baking sheet before transferring to a wire rack.
11. Sprinkle with flaky sea salt if desired and serve warm.
Notes
Freeze the mini marshmallows before mixing them into the dough to help prevent excessive melting while baking.
Do not overbake the cookies because they continue to set as they cool on the baking sheet.
Chilling the dough for 20 minutes creates thicker cookies with extra chewy centers.
