Start by combining creamy almond butter and white sugar in a medium bowl. Add the egg and mix everything thoroughly until you have a smooth cookie dough.
Cut parchment paper to fit your air fryer basket exactly - avoid excess paper on sides as it can blow up and disturb the cookies.
Using a small cookie scoop (about 1.2 tablespoons), place four cookie dough balls onto the parchment paper, spacing them about 2 inches apart.
Create the classic crisscross pattern by gently pressing a fork into each cookie ball twice, making perpendicular marks. Move slowly when lifting the fork to maintain the pattern.
Air fry at 370°F for 6.5-7 minutes until cookies are golden brown around the edges.
Let the cookies rest undisturbed in the air fryer basket for 10 minutes - this step is crucial for proper setting.
Carefully transfer to fresh parchment paper to cool completely.
Repeat the process with remaining dough until all cookies are baked.
Notes
Let your egg come to room temperature for better mixing
Don't skip the 10-minute rest time - cookies are very fragile when hot
Use thin parchment paper for even cooking
Avoid handling hot cookies or trying to reshape them
Make sure your almond butter is well-stirred before measuring
