Combine everything but the chicken in a small bowl. Whisk to dissolve brown sugar
Reserve a couple of spoonfuls of the marinade in a small bowl and place the rest, with the chicken, in a zip-lock bag.
You will use the reserved marinade to baste the chicken with the last five minutes of cooking
Refrigerate for a minimum of 4 hours, but overnight is best
Preheat a grill (or an indoor grill pan or broiler) or preheat oven to 350 degrees F.
Spray cooking surface with cooking spray and place chicken on it to cook
Cook for 5-10 minutes on each side depending on the thickness
Brush with reserved marinade the last few minutes of cooking or grilling.
Notes
Lightly oil your grill grates with a paper towel dipped in vegetable oil. Be careful not to burn your hand.Use a meat thermometer to check the temperature, do not cut into the chicken to see if it is done, this releases all the juices and dries the chicken out. You want a temperature of 165 degrees F.You can also bake this chicken in the oven at 350 degrees F for about 20 minutes, until cooked through. Brush with the reserved marinade the last five minutes.When I bring the meat home from the store, I mix up the marinade and add the meat into it and then freeze it. That way the meat is marinating as it is thawing and it makes for easier and quicker meal prep on those nights when life is busy!
