Here Is How To Make Air Fryer Peanut Butter Cookies

mixing peanut butter with an egg

Air Fryer Peanut Butter Cookies are a simple and delicious dessert made with just 3 ingredients: peanut butter, sugar, and an egg. Mix the ingredients together, form them into balls, and air fry for 5 minutes at 350 degrees for a mouth-melting treat.

This recipe makes about eight cookies.


  • 1 Cup Peanut Butter: Choose a creamy, smooth peanut butter that is free of added oils and sugars. Ensure it is at room temperature, as this will make mixing with the other ingredients easier.
  • 1 Cup Sugar: White granulated sugar works best in this recipe, but you can also use brown sugar or a sugar substitute like Stevia if desired.
  • 1 Egg: Use a large egg at room temperature. If your egg is cold, place it in a bowl of slightly warm water for a few minutes to bring it to room temperature.

  1. Gather your ingredients and equipment: To make these peanut butter cookies, you’ll need a mixing bowl, a cookie scoop or spoon, a fork, an air fryer basket, and a toothpick.
  2. Prepare the air fryer basket: To prevent stickiness, spray the air fryer basket with cooking spray or line it with parchment paper. This will make it easier to remove the cookies once they are cooked.
  3. Mix the ingredients: In a large mixing bowl, add the peanut butter, sugar, and egg. Use a spoon or spatula to mix the ingredients until they are well combined and form a smooth dough.
  4. Scoop the dough: Using a cookie scoop or spoon, portion the dough into rounded balls. Place the cookie dough balls onto the prepared air fryer basket, making sure to space them out evenly.
  5. Flatten the cookies: Use the back of a fork to gently press down twice on each cookie dough ball. This will give the cookies a traditional criss-cross pattern and help them cook evenly.
  6. Cook the cookies: Place the basket in the air fryer and set the temperature to 350°F or 175°C. Cook the cookies for 5 minutes.
  7. Check for doneness: After 5 minutes, use a toothpick to insert it into the center of a cookie. If the toothpick comes out clean, the cookies are done. If the toothpick comes out with dough, cook for an additional minute or two until the cookies are fully cooked.
  8. Serve: Once the cookies are done, remove them from the air fryer basket and let them cool for a few minutes. Serve with a glass of cold milk or a cup of coffee, and enjoy!


You can store the peanut butter cookies in an airtight container or sealable bag for 3-5 days. To soften the cookies, place them in the microwave for a few seconds.


These cookies can be frozen for up to three months. Thaw on the counter or in the microwave before serving.


You can add ½ cup of chocolate chips to the batter, drizzle the cooked cookies with melted chocolate, add ⅓ cup of peanuts or another nut, or even make a peanut butter and jelly sandwich by spreading jelly on one side and smashing two cookies together. The possibilities are endless.

How To Make It Vegan?

Aquafaba is a liquid you see when you open a can of chickpeas, and it makes an excellent vegan egg replacement in baked goods.

To make this recipe vegan, you can substitute the egg with aquafaba, the liquid from a can of chickpeas. Simply drain the chickpeas and reserve the liquid, then whip the aquafaba until it forms soft peaks.

Check out these 17 best egg substitutes for baking.

Use these in place of the egg in the recipe, and use vegan-friendly peanut butter, such as peanut butter made with 100% peanuts and honey or sugar.

Use a vegan alternative like coconut sugar, Stevia, or maple syrup for the sugar. This way, the cookies are vegan yet still maintain the same delicious peanut butter flavor and texture.

Make Them In The Oven

If you don’t have an air fryer, you can make these cookies in the oven. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop the cookie dough onto the prepared sheet and bake for 12-15 minutes or until golden brown. Remove from the oven and let them cool on a wire rack. Enjoy your delicious, oven-baked cookies!
