Make a small batch of Air Fryer Cookies in just 20 minutes! These monster cookies are thick, chewy, and buttery. They're loaded with oats, M&M's, and white and milk chocolate chips.
In a medium sized bowl, using a hand held mixer, beat the butter with the sugars until creamy (30 seconds).
Add peanut butter, egg, and vanilla extract and beat until combined.
Add in the flour, baking soda, and oats, and mix on low speed until just combined.
Fold in or slowly mix in the M&Ms and chocolate chips.
Place a parchment liner in the Air Fryer, and using a medium (2 tablespoons) cookie scoop, scoop cookie balls and place in the Air Fryer. I’m using an XL Cosori basket style Air Fryer and could fit in 5 at a time.
Bake for 6 minutes until they’re lightly browned and cooked through.
Allow the cookies to cool for 1 minute in the Air Fryer basket, then transfer to cool on a wire rack.
Notes
Parchment Liners. These are so useful when using the Air Fryer! They make clean up a breeze and great for baking cookies. The trick is not to add them without any food/cookies on them. So only add the parchment liner after you preheat the Air Fryer. If you add them as you preheat the air fryer, they will move in the Air Fryer and burn.
For better looking cookies, add a few M&Ms to go on top of the cookie dough balls before baking. Do not add chocolate chips, as they seem to burn and change texture with the direct heat of the air fryer.
Be careful not to overbake the cookies. You really don't want your cookies to dry out and become tough. So be sure to check the cookies at 5 minutes as all Air Fryers are different.
Size. I used a medium cookie scoop, and made 18 cookies in total (each about 2 tablespoons). You can make smaller cookies with a small cookie scoop (1 tablespoon size), but don't forget to adjust the baking time.
Change it up! Are you making these for a Christmas party? Use Holiday M&M's. You can also add crushed up pretzels, fold in mini marshmallows, Ande's baking chips, you name it!
Nut-free. Sending the cookies to school? Substitute the peanut butter with Sunbutter, it works so well!
Gluten-free. I often make these monster cookies with all purpose gluten free flour for the whole family to enjoy. Just switch up the flour 1:1 and the texture won't change. Also make sure that your oats are gluten-free certified.
Decorate. If you're making these for a birthday or a halloween party, just add edible eyes to decorate the cookies and have fun decorating! I did that in my Monster Cookie Recipe that I baked in the oven.
