Buttermilk Cupcakes

I had a vanilla buttermilk cupcake recipe that I wanted to test, and after they were done baking, I had some leftover buttermilk and got the idea to try out a vanilla buttermilk frosting as well.  They came out soft, tender, tangy, and delicious!  Once again, I am very bad at photography, so the frosting was a pretty pinkish-purple, with powder blue royal icing flowers.  I also experimented with different piping effects on the top.
