Combine flour, baking powder, salt, and softened butter until the mixture looks like crumbs.
Add Italian seasoning, garlic, and onion powder. Gently fold in until evenly distributed. Do not over mix.
Add the eggs to the mixture. Stir until eggs are well combined in the mixture. Do not over mix.
Slowly stir in milk. Mix until combined. Fold in cheese. Form the dough into a ball.
On a floured surface, roll out biscuit dough until it is about 1/4"-1/2" thickness, depending on preference, with the rim of a cup, cookie-cutter, or canning jar ring.
Spray cooking spray inside the air fryer basket and layer rack (if you choose to use one). Place the cut out biscuits single-layered on the bottom of the basket, and on the rack. Set air fryer temperature to 350 degrees, and the timer to 9 minutes. (If making more than 8 biscuits, it may take a couple of batches to bake all of them). If using a traditional oven, place on greased baking sheets and cook at 400 degrees for 20-25 minutes, or until golden brown.
Once the baking cycle is complete, remove from the basket and allow them to cool on a plate or wire rack. Enjoy as a side dish or for as a snack.
