In a bowl, thoroughly combine ground beef with salt, pepper, paprika and garlic powder. Use a 2 inch food scoop to form into 12 balls.
Place each ball between two 6inch pieces of parchment and use a heavy pan or burger press to flatten out. Repeat with remaining ball.
In a frying pan over medium high heat, add bacon. Cook until crispy and then remove to paper towel covered plate.
In a wide flat pan or on a flat top griddle, over medium high heat, add 2 or 4 (depending on available space) flattened patties. Let cook for about 3 minutes then flip and smash down again. Cook another 3 minutes and then place a slice of cheese on each patty. Cover with lid and let melt for a minute then add 3 pieces of bacon on top of each patty. Stack two patties together and remove from pan. Repeat with remaining burgers.
Build the burger - smear top bun with mayo then add a swirl of ketchup. Place double bacon cheeseburger on bottom bun. Add top bun and pressing down slightly.
