01 - Preheat a grill or large skillet over medium-high heat.
02 - In a mixing bowl, gently combine ground beef, kosher salt, black pepper, smoked paprika, garlic powder, and onion powder until evenly distributed.
03 - Divide beef mixture into four portions and shape each into a patty slightly larger than the buns.
04 - Grill or pan-fry patties for 3 to 4 minutes per side, cooking to desired doneness. During the final minute, place a slice of cheddar cheese on each patty and allow it to melt.
05 - Melt unsalted butter in a skillet over medium heat. Toast buns, cut side down, until golden brown.
06 - Whisk mayonnaise, barbecue sauce, Dijon mustard, hot sauce if using, and brown sugar together in a bowl until fully combined and smooth.
07 - Generously spread crack sauce on both sides of each toasted bun. Layer with shredded lettuce, sliced tomato, and thinly sliced red onion. Add the cheese-topped beef patty and follow with crispy bacon. Cap with the remaining bun half.
08 - Serve immediately with additional crack sauce on the side, if desired.
