Pre-heat the oven to 425 degrees and let your frozen chicken thaw on the counter during this time
Line a sheet pan with parchment paper and spread the chicken on the pan. Don't crowd the chicken if you want crispy wings
Bake for 25 minutes and then flip each wing. Bake for another 15 to 25 minutes based on how crispy you like your wings
Meanwhile, heat the butter and BBQ sauce over medium heat to combine in a large skillet
Add the cooked wings to this skillet to coat and serve
