In a bowl, combine ground beef, bacon bits, cooled sautéed onion, salt, pepper and garlic powder. Gently mix to combine. Form 4 (6oz) patties. Press the center of each burger down with your fingers. Add one (1-inch) cube of ice to each patty. Grease a grill pan or grill. Cook burgers on medium high for 3-4 minutes on each side. Only turn once. For cheeseburger, add cheese after you’ve flipped the burgers. Toast the bun on the grill or in the hot grill pan. Slather the special sauce over bun. Add fixings and burger. Enjoy!
For the Sauce:
Mix together all ingredients in a bowl and whisk until smooth and creamy.
