In a large bowl, combine the buttermilk and hot sauce. Whisk together until well mixed.
Add the chicken tenders to the buttermilk mixture, ensuring they are fully submerged. Cover and refrigerate for at least 2 hours (overnight for best results).
In a separate bowl, mix the flour, paprika, garlic powder, onion powder, black pepper, and salt.
Heat oil in a deep skillet or frying pan over medium-high heat until hot (about 350°F/175°C).
Remove each chicken tender from the buttermilk, letting the excess drip off. Dredge each piece in the flour mixture, pressing lightly to ensure an even coating.
Carefully place the coated chicken tenders in the hot oil, frying in batches to avoid overcrowding the pan. Cook for 4-6 minutes on each side or until golden brown and cooked through (internal temperature should reach 165°F/74°C).
Once cooked, transfer the chicken tenders to a wire rack lined with paper towels to drain excess oil.
Serve hot with your choice of dipping sauces, like honey mustard or ranch dressing.
