I make this recipe in my Cosori 5.8 qt. air fryer. Depending on your air fryer, size and wattages, cooking time may need to be adjusted 1-2 minutes.

FAQ’s

What other ingredients can I put in monster cookies?

Your imagination is the only limitation when making this cookie so whatever flavors you enjoy just go for it and make an exceptional monster cookie that you will love.

How to store leftover cookies?

Allow cookies to fully cool prior to storing them. Place them in an airtight container or resealable storage bag in your refrigerator or at room temperature for up to 3 days. Store in freezer in freezer safe storage bag or an airtight container for up to 6 months.   

Are these cookies easy for kids to make?

I make the base dough and set up a cookie bar. I use a variety of candies, crunched up chips and pretzels, along with different sauces and let the kids make their own decadent crazy creations.

How will I know when my cookie is done?

Different air fryers will possibly have a couple of minutes extra or less cook time so keep an eye on them. When air frying you check the top of the cookie for doneness, and when it is evenly golden brown on all sides, they are finished cooking.
