These enormous cookies are filled with gooey chocolate chips and festive rainbow sprinkles.
In a stand mixer, cream together the cold butter and brown and white sugar for about 5 minutes on medium.
Measure out dry ingredients (except for chips and sprinkles) into a large bowl, mix with a fork, and set aside.
Add eggs and vanilla to stand mixer bowl, scrape down the sides with a rubber spatula, and mix until incorporated.
With mixer on low, slowly add dry ingredients spoon by spoon until fully incorporated.
Add chocolate chips and sprinkles and mix until fully incorporated.
Chill dough in fridge for at least 15-30 minutes. Measure out into large balls. Bigger than a golf ball. I get about 12 balls from a batch.
Bake two at a time on a sheet or pan in air fryer at 350 for 15 minutes.
Allow to cool before eating as they'll be too gooey to eat immediately.
Freeze remaining balls or store in the fridge and use within a few days. Pop the chilled or frozen balls into the air fryer and bake off when you like. If baking from frozen I sometimes add a minute or two to make the center cook more solid. If you bake from frozen for just 15 minutes the center is really gooey and delicious too. It's all about your preference.
I have never baked this exact cookie in a conventional oven. I suspect you could bake at 375F for about 15-18 minutes. If I have a chance to test this out in the conventional oven I will update this post.
