In a large mixing bowl, combine the cooled brewed sweet tea with the buttermilk. Stir gently until thoroughly mixed.
Add the chicken tenders to the marinade, ensuring each piece is fully submerged. Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or overnight for best flavor.
In another bowl, whisk together the flour, cornmeal, smoked paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper until evenly combined.
In a deep skillet or heavy frying pan, pour in enough vegetable oil to cover the bottom by about 1–2 inches. Heat the oil over medium-high heat until it reaches approximately 350°F (175°C).
Retrieve the marinated chicken tenders from the refrigerator. Allow any excess marinade to drip off, then dredge each tender in the flour mixture, ensuring an even coating on all sides.
Carefully add the coated chicken tenders to the hot oil in batches, avoiding overcrowding the pan. Fry for 5-7 minutes per batch, turning them halfway through, until they are golden brown and fully cooked.
Once the chicken tenders are cooked, use a slotted spoon to transfer them to a plate lined with paper towels to absorb any excess oil.
Serve the chicken tenders while they're warm to fully experience the delightful sweetness of the tea paired with the crunchy coating.
Notes
Serve with honey mustard or your favorite dipping sauce, and garnish with fresh parsley or green onions.
