Expresso Cake in a Mug – (Hungry Girl 1-2-3, pg. 89, 147 calories) If you like chocolate cake with a caffeninated boost, this is the recipe for you.  It is easy to make and ready in a matter of minutes.  I chose to use Taster’s Choice instant coffee for this recipe.  I know this is supposed to be a dessert item but I think it would be a great morning or mid-afternoon snack–especially if you are female and enduring a visit from your monthly enemy.
