Add 1 teaspoon of butter to each 4-ounce ramekin and let them warm in the air fryer for 3 minutes.
In a food processor, combine the egg and cottage cheese until mixed, then add the dry ingredients and blend until a wet dough forms.
Use a 1/3 cup measuring cup to scoop out 3 mounds of dough, or a large cookie scoop.
Once the air fryer is ready, take out the ramekins and place the dough mounds inside. If you prefer flatter biscuits for sandwiches, gently press them down.
Cook in the air fryer for 10 minutes until golden brown.
Let cool for 5-10 minutes, then top with a pat of butter and return to the air fryer for a minute to melt.
Store leftovers in an airtight container in the fridge for up to 3 days or freeze for up to 3 months. Thaw before reheating. To reheat, microwave for 30 seconds or warm in a toaster oven at 325°F for 5 minutes.
