mix all hamburger, BBQ, Worcestershire, & liquid smoke

after hamburger and sauces are mixed, grab about 1/3 lb. of hamburger and make Patty. (do this 3 times making 3; 1/3 lb patties )

make a large dimple in the middle of each hamburger patty. place 1 tablespoon of butter in each dimple.

slice about 12 slices off of block of cheddar cheese, each slice around 1/4 of an inch thick.

add 4 slices of cheese to each burger. stacking on top of the butter.

make 3 more hamburger patties. each one being around1/3 of a pound. take the 3 new patties and place on top of butter and cheese. after this pinch the edges of both patties together. ( leaving the cheese and butter in the middle of 3; 2/3 lb. burgers )

rub each Burger with salt and brown sugar

slice a nother 12 slices of cheese off of block of cheddar

fire up the grill. ( I always use charcoal) grill on each side for 7-10 minutes.

after grilling second side for 7-10 minutes, flip burgers once more. add 4 slices of Cheddar to top of each Burger. close lid of grill and keep burgers on grill for 5 more minutes. or until cheese on top of burgers is melted

remove from grill and enjoy with what ever condiments you like .
