Cook bacon completely.
Preheat oven to 375º f. Grease a muffin pan with butter and place one
slice of bread into each hole pressing down in the middle. Press bread
slices into each hole of a greased muffin tin. Crack one egg directly
onto each slice of bread. Place one cooked slice bacon into each egg.
Bake until egg is just cooked, or until desired consistency- yolk runny,
about 10 minutes; slightly runny, about 13 minutes and cooked
thoroughly, about 17 minutes
