Combine all three ingredients in a large mixing bowl. Mix until fully combined.
Chill your cookie mixture in the fridge for 30 minutes.
Using a 1 ½-inch cookie scoop, or heaping tablespoon, scoop the dough onto parchment paper.
Using a fork, press the cookie flat, first in one direction, then again from the opposite direction, to make a crosshatch pattern on top.
Place as many cookies in your air fryer that will fit while giving each cookie a half-inch space. I was able to cook about 4-6 cookies at a time.
Set your air fryer at 370 degrees and cook them for 4 minutes before letting them rest in the air fryer for 4 minutes. Each crispy peanut butter cookie should be lightly browned once cooked. Transfer the peanut butter cookies to a cooling tray. Repeat until you’ve used up all your cookie dough.
Allow the peanut butter cookies to cool completely on the cooling rack.
Once cooled, serve these best peanut butter cookies immediately to enjoy their fresh, irresistible taste.
Notes
Use Real Peanut Butter: The natural peanut butter flavor makes the cookies taste way better than processed peanut butter.Type of Peanut Butter: Ideally, you will use smooth peanut butter to make these peanut butter cookies, however, you can use chunky peanut butter or Jiff’s crunchy peanut butter if desired. Just be sure to stir the chunky peanut butter well before adding it to the other ingredients.Avoid Overbaking: Keep an eye on your cookies and take them out when they’re just barely golden around the edges.
