Ingredients:

  • 1/2 cup Unsalted Butter, softened
  • 1/2 cup Light Brown Sugar, packed
  • 1/4 cup Granulated Sugar
  • 2/3 cup Creamy Peanut Butter
  • 1 Large Egg
  • 1 teaspoon Vanilla Extract
  • 1 cup All-Purpose Flour
  • 1 teaspoon Baking Soda
  • 1/2 teaspoon Fine Sea Salt
  • 1 tablespoon Extra Granulated Sugar (for rolling)

Instructions:

  1. Cream Butter and Sugars: In a large bowl, use a mixer to beat the softened butter, brown sugar, and granulated sugar until light and fluffy (about 3 minutes). Scrape down the sides of the bowl.
  2. Add Wet Ingredients: Beat in the peanut butter until fully combined. Add the egg and vanilla extract, mixing until just incorporated. Do not overmix this stage.
  3. Combine Dry Ingredients: In a separate medium bowl, whisk together the flour, baking soda, and salt.
  4. Incorporate Dry into Wet: Gradually add the flour mixture to the wet ingredients, mixing on low speed only until just combined. Stop mixing immediately when no dry streaks remain.
  5. Chill the Dough: Wrap the dough in cling film or place it in an airtight container. Refrigerate for a minimum of 30 minutes (up to 2 days). Chilling is non-negotiable for air fryer success.
  6. Preheat and Prepare: Preheat the air fryer to 325°F (160°C). Place the 1 tablespoon of extra granulated sugar in a shallow dish for rolling.
  7. Scoop and Shape: Scoop the chilled dough using a cookie scoop (about 3 tablespoons of dough per cookie). Roll the dough into smooth balls.
  8. The Criss-Cross: Roll each ball lightly in the reserved granulated sugar. Press down gently with a fork to create the classic criss-cross pattern.
  9. Air Fry in Batches: Line the air fryer basket with a fitted piece of parchment paper. Place 3–4 cookies in the basket, ensuring they have at least 1 inch of space between them. Do not overcrowd.
  10. Cook: Air fry at 325°F (160°C) for 6 to 8 minutes. Pull the cookies out when the center looks slightly underbaked.
  11. Cool: Immediately transfer the cookies using a thin spatula to a wire cooling rack. Allow them to cool completely (10–15 minutes), as they will firm up as they cool.
  12. Repeat steps 9 through 11 for all remaining batches of dough.
