Preheat the oven to 180 degrees. Butter all the slices of bread on both sides.
Assemble the sandwich: one slice of bread, one slice of cheese, one slice of ham, then another slice of cheese. Use a round cutter and cut through the ham, cheese, and bread. Top with a slice of bread without a hole.
In an oven-safe skillet, place the sandwiches with the hole facing down until they are golden brown. Flip the sandwiches and crack the egg into the hole.
Transfer the skillet to the oven and cook until the egg is set, about 10 - 12 minutes.
