I think that the best part of this recipe is how versatile it can be without spending a lot of time! You could throw a dash of cinnamon or a little lemon zest into the batter before cooking. Or, after baking, add a handful of chocolate chips, or a handful of blueberries (or other fresh fruit). (I find that the mug pancake has the nicest texture if you just cook it plain and add in the chocolate chips or blueberries after cooking, but you are welcome to try it either way.)
