01 - Combine ground beef with kosher salt, black pepper, and garlic powder in a large bowl. Gently mix until just incorporated. Form into 4 equal patties, pressing a shallow thumbprint into the center of each to prevent puffing during cooking.
02 - Heat grill or cast-iron skillet over medium-high heat until hot.
03 - Fry bacon strips until crispy and golden brown. Transfer to paper towels to drain excess grease.
04 - Place patties on hot grill or skillet. Cook for 3-4 minutes per side for medium doneness. During the final minute, place cheddar slice on each patty and cover to melt cheese.
05 - Whisk together mayonnaise, sour cream, shredded cheddar cheese, ranch seasoning, and fresh chives in a small bowl until smooth and well combined.
06 - Lightly butter brioche buns if desired and toast on grill or in a skillet until golden brown.
07 - Generously spread crack sauce on both cut sides of each bun. Build each burger starting with lettuce on the bottom bun, followed by tomato slices and red onion. Place cheesy patty on top, add 2 crispy bacon slices, and finish with pickles. Cap with top bun and serve immediately.
