01 - Divide ground beef into four equal portions and flatten each into patties approximately 1/3 inch thick.
02 - Generously season both sides of each patty with kosher salt and freshly ground black pepper.
03 - Place skillet or grill over medium-high heat and add butter or neutral oil.
04 - Cook patties for 2 to 3 minutes per side until well-browned and cooked through to an internal temperature of 160°F.
05 - During the final minute of cooking, place a cheese slice atop two patties and allow to melt completely.
06 - Stack one cheese-topped patty with one plain patty, cheese side facing down, creating two double-patty burgers with cheese layered between.
07 - Layer optional toppings including pickles, tomato, grilled onions, and lettuce between patties as desired.
08 - Plate immediately while cheese remains melted and patties are piping hot.
