Ingredients
  

Essential Ingredients
  • 1 cup creamy peanut butter room temperature for best mixing
  • ¾ cup granulated sugar
  • 1 large egg

Equipment

  • Air fryer
  • large mixing bowl
  • fork
  • measuring cups
  • - Measuring spoons
  • parchment paper
  • wire cooling rack

Method
 

  1. Gather all ingredients and equipment on a clean counter. Ensure your air fryer is clean and ready for use. Tear parchment paper into basket-sized pieces for easy cleanup.
  2. In a large bowl, combine peanut butter, sugar, and egg thoroughly. Mix until the mixture becomes smooth and creamy without lumps. This process takes approximately 2-3 minutes of vigorous stirring.
  3. Roll the peanut butter mixture into small balls, about one tablespoon each. Aim for uniform size to ensure even cooking. Slightly wet hands prevent sticking while rolling.
  4. Line your air fryer basket with parchment paper or silicone liner. Arrange cookie balls about one inch apart for proper air circulation. Work in batches if necessary.
  5. Using a fork, flatten each cookie ball gently. Create the traditional crisscross pattern by pressing perpendicular lines. This technique helps cookies cook evenly throughout.
  6. Cook at 300°F for 7-8 minutes until your 3 ingredient peanut butter cookies air fryer batch turns golden brown. Avoid opening the air fryer frequently, as this releases heat. Check only during the final minute.
  7. Allow cookies to set in the basket for 2-3 minutes after cooking. This prevents breaking when transferring. Use a thin spatula for easy removal, then transfer cookies to a wire rack for complete cooling.

Notes

Temperature matters significantly - 300°F provides optimal cooking without burning. Cookie size affects cooking time, so larger cookies require additional minutes. For make-ahead convenience, prepare cookie dough balls in advance and freeze them. Store finished cookies in airtight container at room temperature for 5-7 days.
