Chocolate Lava Cupcakes

I've tried a couple of such desserts at various restaurants, and they never fail to up the wow factor when the melted chocolate flows out as the fork shaves a corner away. Without any experience with melting chocolate, I procrastinated despite collecting a few recipes till I saw this simple recipe on Suyin's blog. It only calls for one egg and uses Lindth chocolate to create the lava centre! If not eaten fresh from oven, microwave before serving.. Yumz!
