In a large bowl, combine flour, breadcrumbs, garlic powder, ground black pepper, and salt. Mix until combined.
Add in the cheese and the corn kernels until all coated with flour/breadcrumbs mixture, mix until all is combined, and finally add in the corn kernels.
Next, add in the eggs and sour cream. Mix until all is combined. The dough will be very sticky. You can use a fork, or I use my dough hook.
Use a cookie scoop (I like using OXO medium size scoop 1 ½ tablespoon) and scoop up some corn fritter mixtures into a ball. You should have seven corn fritter balls. Use your hand and flatten out each dough to a small but thick pancake.
Place four corn fritters in the prepared air fryer basket and cook for 7 minutes at 370 degrees F on a manual setting. Flip them and cook for an additional 6 to 7 minutes or until golden. You should have only two batches to do.
Repeat this process until there are no more corn fritters. Once the corn fritters are cooked, place them on a cooling rack and cool off for 5 minutes.
