This recipe yields two dozen muffins. A note, when the muffins have finished baking, check for doneness by plunging a toothpick into one of the muffins. There is a very good chance that your toothpick will pierce a melty chocolate chip instead of the batter, thus you will likely need to test several areas of a muffin to check if the batter has baked completely. If the toothpick comes out clean, then they are done baking; if the toothpick is coated with batter, then bake the muffins for about five minutes longer.
