Combine beef, finely chopped bacon, salt and pepper, and then form into four patties. Cook on a hot grill to preferred doneness, about 3-4 minutes a side for medium-rare. Turn the heat off, place cheddar slices on top of burgers and close the grill lid to allow cheese to melt.

Heat a large skillet on medium-high heat. Add chopped bacon and cook until crispy. Melt in butter then add corn, jalapeno, green onion, salt and pepper to the skillet. Cook until corn is just tender, about 2-3 minutes. Stir in maple syrup and remove the skillet from the heat. Mash avocado flesh with salt and pepper, then spread equally on the bottom of each bun. Top with cheeseburger patty and sweet corn relish.
