In a mixing bowl, combine the cottage cheese, almond flour, shredded cheddar cheese, eggs, baking powder, garlic powder, salt, and black pepper. Mix until the ingredients are well combined and form a thick batter.
Preheat your air fryer to 350°F (175°C). If desired, line the air fryer basket with baking parchment paper to prevent sticking.
Using a spoon or spatula, scoop about 2 tablespoons of the biscuit batter and shape it into a round biscuit, then place it in the air fryer basket. Repeat this process until you have formed all biscuits, ensuring there is space between each biscuit for proper air circulation.
Lightly spray the tops of the biscuits with cooking spray for added crispiness, if desired.
Cook the biscuits in the air fryer at 350°F (175°C) for 10 minutes. After 10 minutes, check for doneness. If they are golden brown and cooked through, remove them from the air fryer. If not, cook for an additional 3-5 minutes, checking in intervals.
Once cooked, remove the biscuits from the air fryer and let them cool for a few minutes before serving.
