01 - Preheat a grill or large skillet over medium-high heat until smoking slightly.
02 - In a large bowl, combine ground beef with kosher salt, black pepper, smoked paprika, garlic powder, and onion powder. Mix gently until just incorporated, being careful not to overwork the meat. Divide into 4 equal portions and shape into patties slightly wider than the buns to account for shrinkage during cooking. Press a small dimple in the center of each patty to prevent puffing.
03 - Place patties on the hot grill or skillet and cook for 3 to 4 minutes per side until desired doneness is reached. During the final minute of cooking, lay one slice of cheddar cheese on each patty and allow it to melt. Transfer to a plate and rest briefly.
04 - Melt unsalted butter in a skillet over medium heat. Place buns cut-side down and toast until golden brown, approximately 1 to 2 minutes. Remove and set aside.
05 - In a mixing bowl, whisk together mayonnaise, barbecue sauce, Dijon mustard, hot sauce, and brown sugar until smooth and well combined. Taste and adjust heat level as desired.
06 - Spread crack sauce generously on both the bottom and top halves of each toasted bun. Layer shredded lettuce, sliced tomato, and red onion on the bottom bun. Place the cheesy patty on top, followed by 2 strips of crispy bacon. Cap with the top bun.
07 - Serve immediately while hot. Offer additional crack sauce on the side along with optional toppings such as pickles or sliced jalapeños.
