Description

Soft, chewy, flourless 3-ingredient peanut butter cookies in the air fryer. Just peanut butter, sugar, and an egg — naturally gluten-free and ready in under 15 minutes.

Ingredients 

  • 1 cup peanut butter, (Jif or Skippy recommended)
  • 1 cup granulated sugar, (or light brown sugar)
  • 1 large egg
  • Optional: 1 tablespoon extra granulated sugar for fork-pressing

Instructions

  • In a medium bowl, mix peanut butter, sugar, and egg until smooth and fully combined.
  • Cover and refrigerate for 30 minutes.
  • Line your air fryer basket with parchment paper trimmed to fit. Scoop dough into 1-tablespoon balls and place on the parchment, leaving ½ inch between each.
  • Dip a fork in sugar and press a crisscross pattern into each cookie.
  • Air fry at 325°F for 6–7 minutes, until edges are just golden.
  • Let cookies rest in the basket for 4–5 minutes before transferring to a wire rack.
  • Repeat with remaining dough, keeping it chilled between batches.

Equipment

Notes

Notes: Use commercial peanut butter (Jif, Skippy) for best results. Natural peanut butter works but may spread more. Cookies will look slightly underdone when removed — they finish setting in the basket. To bake in oven: 350°F for 10–12 minutes.
