Cupcake city

I have volunteered to donate 300 mini cupcakes to the Relay for Life walk and a local art show. I spent my day test baking different flavors and icing with part success. The first flavor I made was homemade lemon with vanilla icing. The lemon cupcakes turned out fabulous, the icing not so much. I need to find a recipe for thinking up my icing so it don't just fall apart when it is piped one. The second cupcake I made was Pink Lemonade. The cake was moist an very pink lemonady, however I believe it was entirely too sweet, especially with the lemonade icing. I have decided to make the lemon cupcakes along with chocolate for the donations. Simple, tasty and easy to make.
