Start by placing your chicken thighs and drumsticks onto a cutting board. Season them with salt and pepper.
Then in a large Ziploc bag, pour the buttermilk, salt, and pepper and mix well.
Add your chicken to the buttermilk. Let soak overnight or for at least 1 hour.
Then add the flour, garlic powder, paprika, and baking powder to a large Ziploc back and shake so all of the flour and spices are well blended.
Then remove the chicken and dredge it into the flour mixture, shaking off the excess. As you do this, place them in your air fryer basket. Continue until all of the chicken has been coated in the batter.
Then completely spray the chicken until you have an oil mist covering it, if you do not you will have white patches on your chicken.
And as mentioned in the list of items I used, in this recipe, above., this is the oil sprayer I use.
Set your temperature to 380 degrees for 10 minutes.
Then check on your chicken, and respray them, using the olive oil spray.
Set another 10 minutes at 380 degrees F.
Before you remove your chicken, check with a meat thermometer and make sure that the thickest part of the chicken reads 165 degrees F.
When the chicken is completely cooked through, remove, plate and serve.
