Preheat oven to 425 degrees F. Line a large baking sheet with foil and set a baking rack on top if you have one. If you don’t have a baking rack just spray the foil with nonstick cooking spray.
Pat the chicken dry with paper towels. This is really important to get super crispy skin.
In a large zip-top bag, combine flour, baking powder, salt, garlic powder, paprika and black pepper. Place the chicken in the bag a few pieces at a time and shake to coat. Set chicken pieces skin side down on the baking rack that has been placed on top of the baking sheet (or on the foil lined baking sheet that’s been sprayed with nonstick cooking spray). Place larger pieces toward the outside; pieces can be close together but should not touch.
Bake in the preheated 425 degree oven for 45-50 minutes, turning over after 30 minutes. Juices should be clear and temperature should register 165-170 degrees. For a more golden color, spray with olive oil cooking spray and turn on the broiler for a few minutes, watching closely to ensure the chicken doesn't burn.
Let cool 5-10 minutes before serving.
Notes
Make sure to really pat the chicken dry with paper towels. The less moisture in the skin, the crispier it will get. If you have the time, pat the drumsticks dry and lay the out on a baking sheet and pop them in the fridge for a few hours, or even overnight.
The baking powder is a key ingredient for crispiness. You can use less, but don't omit it.
Store leftovers in an airtight container or resealable plastic bag in the fridge for up to 3-4 days or freeze for up to 6 months in an airtight, freezer safe container. Thaw completely before reheating.
Reheat in the microwave for 60-90 seconds, but keep in mind the skin will not be crispy. I recommend heating at 350℉ for 5-10 minutes in the oven or in an air fryer. You can also just eat it cold!
