Oven Baked BBQ Chicken

I saw this recipe on Culinary Covers and thought it would be the perfect way to fix the chicken legs we had in the freezer.  The BBQ sauce on these are awesome.  This is a great recipe!

6 tbsp packed light brown sugar (divided)
1 1/4 tsp kosher salt (divided)
2 tsp freshly ground black pepper (divided)
1 tsp smoked paprika
1 tsp garlic powder
1-2 lbs bone in chicken (any pieces work)
1 1/2 cups ketchup
1/4 cup Worcestershire sauce
3 tbsp yellow mustard
2 tbsp apple cider vinegar
1 1/2 tbsps fresh lemon juice
2 tbsp vegetable oil

Heat oven to 350. In a bowl mix together 2 tablespoons of brown sugar, 1 teaspoon of salt, 1 teaspoon of pepper, the paprika and the garlic powder.  Rub the mixture over the chicken pieces.  In a medium saucepan combine the remaining brown sugar, salt and black pepper with the ketchup, worcestershire sauce, mustard, apple cider vinegar and fresh lemon juice. Cook over medium low heat while stirring for five minutes. Turn heat down.  In a pan heat the vegetable oil.  Brown the chicken pieces in the oil for 3 to 5 minutes on each side.  Place on a lined baking sheet.  Remove 1/2 cup of the bbq sauce from the saucepan and place in a small bowl.  Brush the chicken with the BBQ sauce. Bake the chicken in the oven for 25 to 35 minutes or until chicken is completely cooked through.  Brush with the BBQ sauce from the sauce pan.  Serve the chicken with the remaining sauce on the side.
