   2. Crack an egg onto the butter and sugar mixture, and use a fork to whisk it well into the mixture. Place flour, baking soda, and salt on top, and very carefully stir into the mixture until smooth and well-mixed. Stir in chocolate chunks. Place in the oven for 15-20 minutes*, or until starting to turn golden on the top and around the edges, but soft in the center. Serve with vanilla ice cream.

   * As many readers have pointed out, cooking time can vary greatly. When I doubled this recipe, for instance, I made it in a larger pan, and the cooking time was probably around 35 minutes. Also, it will depend on how hot your pan is when you put it in the oven, the size of it, and how well it conducts heat. When you're making it, judge the cooking time according to the doneness of your preference. You may have to wait a little longer than the recipe says, but you won't be sorry.
