Heat up a pan with a little bit of oil. Set your cooker to a low heat or you will burn the eggs. Place your heart shaped cookie cutter in to the center of the pan. Place it with the smooth side down or you might end up scratching the pan.
Crack and egg and pour it in to the center of the cookie cutter. A bit of egg will probably slip under the cutter so hold it down to ensure that most of it doesn't.
Use a spatula to remove any excess egg from the outside of the cookie cutter. Remove the cookie cutter and let the egg cook for a few more seconds before removing it with the spatula.
