What you need (per the original recipe):
With a hand mixer, cream together the butter and sugar. Add the vanilla and mix well. Add the flour and salt and mix until combined. I slowly added my flour a little at a time. I think it keeps it from going everywhere. Add the milk gradually until desired consistency is reached. The original recipe calls for about 4 tbsp of milk; however, it was really thick to me after this and I ended up about about twice that much so I could spread it on the cupcakes without tearing them. Gently fold in chocolate chips. The recipe says 1 cup but I just kept adding until it looked like the right amount to me. I used probably 1 1/3 cups of chips overall. Frost cooled cupcakes. Store in refrigerator.
My husband loved these. I am not a big icing fan and even I liked them. I sent one batch to Bill's office and my cupcake plate was returned to me at lunch empty so it seems like engineers like cupcakes a lot! Overall, this recipe was a success!
