01 - Combine ground beef with kosher salt, black pepper, and garlic powder in a large bowl. Gently mix until incorporated, being careful not to overwork the meat. Shape into 4 uniform patties, pressing a shallow indentation into the center of each to prevent puffing during cooking.
02 - Heat grill or cast iron skillet over medium-high heat until properly preheated.
03 - Fry bacon slices until crispy and golden brown. Transfer to paper towels to drain excess grease.
04 - Place patties on preheated grill or skillet. Cook for 3 to 4 minutes per side for medium doneness, adjusting time to your preference. During the final minute of cooking, place a cheddar cheese slice on each patty and cover to allow cheese to melt completely.
05 - Whisk together mayonnaise, sour cream, shredded cheddar cheese, ranch seasoning mix, and fresh chives in a small bowl until smooth and thoroughly combined.
06 - Lightly toast brioche buns on the grill or in a toaster until golden brown and slightly crisped.
07 - Generously spread crack sauce on both top and bottom bun halves. Build each burger by layering shredded lettuce, tomato slices, and red onion on the bottom bun. Place the cheesy burger patty on top, add 2 crispy bacon slices, and finish with pickle slices if desired. Cap with the top bun and serve immediately.
