To Marinate Chicken: In a large bowl, whisk the buttermilk, egg, garlic powder, salt, and black pepper. Add the chicken tenders and mix until fully coated. Cover and marinate for 30 minutes or overnight.
To Cook Chicken: In a shallow bowl, whisk the flour, cornstarch, and spices. Add the chicken into the flour, pressing the flour into the chicken, fully coating all sides.
Heat 2-3 inches of oil in a deep heavy-duty skillet to about 350ºF. Add chicken tenders to oil (without overcrowding) and cook 5-7 minutes or until the tenders are crispy and the chicken is cooked through. Serve immediately with sauce and your favorite coleslaw.
To Make the Sauce: Place all the ingredients into a bowl and stir to combine. Cover and place in the fridge until ready to use.
