Orange Chocolate Chip Muffins

I can't stop baking! Seriously. I think it's a problem. Because I still have homemade marmalade from a batch that a friend gave me, and given my baking problem, I decided to make a sweet, orange-y baked good. These were easy to throw together and you could make a lot of variations of it as well. Instead of chocolate chips, you could add cranberries, almonds, walnuts, whatever. This recipe makes about 15 cupcakes and is an adaptation of this original recipe.
