01 - Gently mix ground beef with salt, pepper, and garlic powder in a large bowl. Form into 4 equal patties, pressing a slight indentation into the center of each to prevent puffing during cooking.
02 - Preheat grill or skillet over medium-high heat.
03 - Cook bacon until crispy and drain on paper towels. Set aside for assembly.
04 - Grill or pan-fry patties for 3-4 minutes per side until desired doneness. Place cheddar cheese slice on each patty during the final minute, cover, and allow to melt completely.
05 - Combine mayonnaise, sour cream, shredded cheddar, ranch seasoning, and chives in a small bowl. Mix until thoroughly incorporated and smooth.
06 - Lightly toast brioche buns until golden brown.
07 - Spread crack sauce on both bun halves. Layer bottom bun with shredded lettuce, tomato slices, and red onion. Place cheesy patty on top, add 2 bacon slices, and garnish with pickles if using. Crown with top bun and serve immediately.
