Vanilla Buttermilk Cupcakes

I have about 2 liters of buttermilk to use up.  I've done buttermilk pancakes and buttermilk scrambled eggs.  Now it's vanilla buttermilk cupcakes... with chocolate chips and frosted with peanut butter frosting.

I've always considered my vanilla cupcake recipe to be the best, and never thought that I could find one that I could like more.  But this vanilla buttermilk cupcake is really better!  The texture is better, and the taste superb! 

The downside?  This cupcake is more expensive to make because of the buttermilk.
