Air Fryer
Parchment paper liners You can use regular parchment paper, but I like these square air fryer parchment paper liners. They are easy to use, inexpensive and work great!

Ingredients

Instructions

Combine all three ingredients in a medium mixing bowl. Mix until fully combined.
Chill 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 one direction, then again from the opposite direction to make a crosshatch pattern on top.
Line the bottom of your air fryer with parchment paper. Be sure to not have extra parchment paper running up the side of the air fryer or it will get caught by the air and fold over the cookies.
Place as many cookies in your air fryer that will fit, while giving each cookie a half inch space. I was able to do about 4-6 at a time.
Set your air fryer at 370 degrees ON THE AIR FRYER SETTING and cook them for 4 minutes before letting them rest in the air fryer for 4 minutes. IMPORTANT RECIPE NOTE: THE AIR FRYER SHOULD BE TURNED OFF AFTER 4 MINUTES, BUT THE COOKIES NEED TO REMAIN IN THE AIR FRYER FOR AT LEAST 4 MORE MINUTES AS THEY WILL CONTINUE TO BAKE AS THE AIR FRYER COOLS DOWN. CHECK THEM AND IF THEY HAVE FIRMED UP, REMOVE THEM FROM THE AIR FRYER AND ALLOW THEM TO COOL ON THE COUNTER FOR ADDITIONAL 5 MINUTES.
Repeat until you’ve used up your batter. Enjoy!

Notes

NOTE: COOKING TIMES CAN VARY FROM MAKE, MODEL AND SIZE OF AIR FRYER.
It’s important that you do not skip the chilling step. The air fryer will make the cookies spread and be crumbly more than the oven. The chilling step keeps them from spreading too much and keeps them from being a crumbly mess when leaving the air fryer.
It’s also very important to not touch the cookies until they’ve set for a minimum of 4 minutes. This allows them to set up and not fall apart when removed from the air fryer.
I like to shape the parchment paper to the bottom of my air fryer, then pull it out and prepare my cookies on it. This way, I can just set the parchment paper back inside without having to set one cookie at a time inside the air fryer.
Each air fryer is a different shape. Mine allowed for 4-6 cookies at a time, but your shape might not allow that many, and it may allow for more. Just be sure to give enough space for the cookies to spread a bit and you’ll be good to go.
Putting more or less cookies doesn’t require you to adjust the cook time or rest time.
This cookie dough is very sticky, so it’s best to not get your hands involved in the scooping process and stick to a scoop or spoon.
Each air fryer has various cooking settings. If your air fryer doesn’t have a 370 degree setting, choose the closest step under it as opposed to over it.
