Chocolate stuffed vanilla cupcake

I baked four cupcakes yesterday, one of which was not stuffed.  The plain cupcake was for Robert; his pediatrician said he can now eat anything except nuts and honey.  I used this vanilla pound cake recipe halving everything except the sugar (Hawaiian sugar in the raw) which I quartered and doubling the amount of vanilla extract.  I used white whole wheat flour and organic milk and eggs.  Robert enjoyed his first cupcake!
