Preheat the oven to 425°F or 220°C. Line two large rimmed baking pans with parchment paper and place a wire rack on each pan.
In a large bowl, combine the flour, 1 tablespoon paprika, 1 tablespoon garlic powder, onion powder, 1 teaspoon salt, and black pepper. Add the chicken tenders and toss to coat.
In a separate bowl, whisk the eggs with the remaining paprika, garlic powder, and salt. Place the crushed cornflakes in a third bowl.
Dip each chicken tender into the egg mixture, then press into the crushed cornflakes until well coated. Arrange on the wire racks and drizzle or spray lightly with olive oil.
Bake for 15 minutes, flip, then bake for another 10 to 15 minutes until golden, crispy, and cooked through. Let rest for 6 to 8 minutes.
Meanwhile, add the olive oil, butter, honey, white vinegar, apple cider vinegar, lemon juice, and salt to a small saucepan. Bring to a gentle boil, reduce the heat, and simmer for about 5 minutes until slightly thickened.
Brush the warm glaze over the chicken tenders just before serving.
