Fill each muffin one at a time, by breaking egg into small dish, with a slotted spoon very carefully transfer egg yolk to corn muffin hole, add as much egg white as will fit. The reason for this is homemade corn muffins can be to small to hold the entire egg. Most bakery muffins will hold the entire egg fine.Bake on prepared pan 8 to 15 minutes depending on how well done you like your eggs Keep in mind the egg will continue cooking from the heat of the muffin.
