I am getting ready to have a few friends over for a candle party and it is right around St. Patrick’s Day so I thought I would try out a new cupcake recipe.  The cupcakes are lime flavored with a lime cream cheese frosting.  Feeling the spirit of St. Patrick’s Day I decided to add green food coloring to the mix and the cupcakes turned out so cute and festive.  I also added a few green colored sprinkles to the tops of the cupcakes but I did not count these into the nutrition info.

Skinny Mom Fact: Many bars in the United States, and abroad, serve green beer to celebrate St. Patty’s Day.

*I understand that the word healthy holds a different meaning for every individual, and I am not claiming the diet soda in this recipe makes these cupcakes healthy. For me, it is important to cut calories and fat in my cooking — making them skinny — and this is a trick I’ve learned along the way. I understand the research on diet soda. I am human and I occasionally enjoy a diet soda…even in my baking. If this recipe offends anyone, I apologize, and you can still cook these divine cupcakes with the traditional baking ingredients.
