Layer wings in slow cooker set on low heat. Between layers, evenly season with bbq seasoning.
When you have layered all the wings, slowly pour in the beer. Let cook for 5 hours.
When wings are cooking place all the ingredients for the sauce in a sauce pan.
Whisk together so ingredients combine and place over medium heat, stirring until the brown sugar dissolves.
Let mixture come to a bowl for 3 minutes and continue to stir. Take sauce off the heat and let cool until ready to baste chicken wings.
After the wings have cooked for 5 hours, place on a sheet tray and place in a pre heated 350 degree over. Let cook for 30 minutes, so most of the cooking liquid from the slow cooker evaporates.
Turn wings over with a tong, and brush with bbq sauce. Let cook 20 minutes. Take wings out again and flip, basting in more sauce. Let cook an additional 20 minutes.
Serve and enjoy!
