Preheat the oven. Preheat to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease it.
Prepare the breading stations. Set out three shallow bowls. Add the flour to the first bowl. Whisk together the eggs and milk in the second. In the third, combine the breadcrumbs, garlic powder, paprika, salt, and black pepper.
Bread the chicken. Working with one tender at a time, dredge it in the flour, shaking off any excess. Dip into the egg mixture, letting the excess drip off, then press into the seasoned breadcrumbs until evenly coated on all sides.
Arrange on the baking sheet. Place the breaded chicken tenders on the prepared baking sheet, leaving a little space between each piece. Lightly spray the tops with cooking spray to help the coating turn golden and crispy.
Bake until golden. Bake for 18–20 minutes, turning halfway through, until the coating is golden and crisp and the chicken reaches an internal temperature of 165°F (74°C).
Serve. Serve immediately with your favorite dipping sauce.
