Preheat your oven to 400°F (204°C) and line two large baking sheets with parchment paper or silicone baking mats.
Place the chicken pieces in a large bowl, sprinkle the flour over them, and toss until every piece is evenly coated.
In a separate bowl, stir together the crushed corn flakes, salt, pepper, garlic powder, and smoked paprika.
In a smaller bowl, whisk the eggs with the milk until the mixture is smooth.
Dip each piece of chicken into the egg wash, let the extra drip off, then roll it in the cornflake mixture, shaking off any loose crumbs, and place on the prepared baking sheet.
Repeat with all the chicken, then bake for 18 minutes, flipping the pieces halfway through, until the chicken is golden and crisp.
While the chicken bakes, combine the BBQ sauce, honey, and ketchup in a small saucepan over medium heat and cook for about 5 minutes, whisking occasionally until the sauce is smooth and glossy.
Let the baked chicken cool for 5 minutes, then move it into a large bowl, pour the warm sauce on top, and gently stir until every piece is coated.
Serve the chicken bites warm, or store leftovers in the refrigerator for up to a week and reheat in the microwave until heated through.
