Cook the bacon in a large skillet over medium heat until crisp, about 8-10 minutes.

Use a drinking glass and cut a hole in the middle of each slice of bread.

When the bacon is cooked, remove from pan and cut in half crosswise and set aside. Pour out half of the bacon fat into a small bowl. Place the two slices of bread in the pan cook until the bottom side is just getting golden brown, about 2-3 minutes.

Crack an egg into each hole in the bread, season eggs with salt and pepper to your liking and cook until the underside is set, about 2 minutes.

Flip each slice over to set the whites and cook for about 1 minute. The intention is to have set whites and a runny yolk. Add the butter to pan and tilt the pan back and forth to distribute the butter evenly.

Flip the bread over again and top one slice with the cheese slices, then the bacon, and add the other slice on top. Transfer to a place, cut in half through the yolk, enjoy.
