Set your oven to 350°F and line a baking tray with parchment paper.
In a large shallow pan, whisk together flour, garlic pepper, sugar, and paprika.
In a bowl, whisk milk, eggs, baking powder, and baking soda until smooth.
Dip each chicken piece into the milk mixture, then into the flour mixture. Repeat for a second coat.
Place the coated chicken pieces on the tray. Drizzle with olive oil to help crisp the crust.
Bake for 50–55 minutes, flipping halfway through, until the chicken is golden brown and cooked through.
