Start by seasoning your chicken with salt and pepper. Cut your pieces into 1-inch pieces.
Then in a medium-sized bowl, mix the flour and baking powder.
In another mixing bowl, blend the buttermilk, tabasco sauce, and egg (combine well)
Dip the chicken into the flour mixture, shake the chicken after you dip it in the flour mixture to get rid of all of the extra flour.
Then dip the chicken into the buttermilk mixture, shaking off the excess.
Then return the mixture to the flour mixture.
As you coat the chicken, either place it in an air fryer basket or Air Fryer tray (both should be sprayed with olive oil, so the chicken doesn't stick, as it is cooking)
Once your tray is loaded, being careful not to overcrowd the basket, spray it generously with olive oil spray.
Set your air fryer to 400 degrees for 5 minutes, flip them, and cook for another 5 minutes. NOTE: Before you flip them, coat them again with a generous amount of olive oil spray.
To prepare the sauce: Mix the ingredients and simmer for about 10 minutes in a small pan.
Then add the chicken (cooked) to a large mixing bowl, pour the BBQ sauce over the chicken and toss with tongs to evenly coat.
Plate, serve and enjoy!
