Method
- 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.
- 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.
- 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.
- 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.
- Using a fork, flatten each cookie ball gently. Create the traditional crisscross pattern by pressing perpendicular lines. This technique helps cookies cook evenly throughout.
- 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.
- 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.
