Step 1: In a large bowl, gently combine the ground beef with garlic powder, onion powder, smoked paprika, black pepper, and salt. Avoid overmixing.
Step 2: Divide the seasoned ground beef into 8 equal portions. Form each portion into a thin, flat patty, about 4 inches in diameter.
Step 3: Place one cheddar cheese cube in the center of four of the patties. Top each cheese-covered patty with another plain patty.
Step 4: Carefully pinch and seal the edges of the top and bottom patties together all around the cheese cube, ensuring no gaps remain to prevent cheese leakage during cooking. Form into a neat, uniform burger shape.
Step 5: Preheat your grill or a large skillet over medium-high heat. Lightly oil the cooking surface.
Step 6: Place the cheeseburger lava cakes on the hot surface. Cook for 6-8 minutes per side for medium-rare, or longer to your desired doneness, ensuring a beautiful sear and that the cheese is fully melted and molten.
Step 7: Once cooked, remove the lava cakes from the heat and let them rest for 5 minutes.
Step 8: Serve immediately on toasted hamburger buns with your favorite toppings and condiments.
