Ingredients
2 ½ cups (315g) all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
1 cup (226g) unsalted butter, softened
¾ cup (150g) granulated sugar
¾ cup (165g) packed brown sugar
2 large eggs
2 teaspoons vanilla extract
1 cup (250g) creamy peanut butter
1 cup (100g) marshmallow fluff (plus extra for topping, optional)
Instructions
1. Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.
2. In a large bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes.
3. Beat in eggs one at a time, followed by the vanilla extract.
4. In a separate bowl, whisk together flour, baking soda, and salt.
5. Gradually add the dry ingredients to the wet mixture, mixing just until combined.
6. Add creamy peanut butter and mix until smooth and fully incorporated.
7. Chill the cookie dough for at least 30 minutes for best texture.
8. Scoop rounded tablespoons of dough (about 2 tablespoons each) and place 2 inches apart on prepared baking sheets.
9. Bake 8–10 minutes, or until edges are lightly golden and centers look slightly soft.
10. Immediately after baking, press a small dollop of marshmallow fluff into the center of each warm cookie.
11. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Storage:
• Store cooled cookies in an airtight container at room temperature up to 4 days.
• For longer storage, freeze cookies for up to 3 months; thaw at room temperature before serving.
Tips:
• Don’t skip chilling — it prevents spreading and gives chewier cookies.
• For extra flair, swirl the marshmallow fluff on top before baking for a marbled look.
• Use creamy peanut butter (like Jif or Skippy) for best texture; natural peanut butters may make dough oily.
• Add chopped peanuts or mini chocolate chips for a fun twist.
