Chocolate Earthquake Cookies

This morning in Berkeley, CA, we had a loud rattling earthquake. It was a 4.1 which isn't really all that strong, but my house was close to the epicenter, so we felt it. My cat and I were enjoying a cup of tea--well, I was--when things started to rock and roll. Nothing broke or fell off, but it was loud and shaking.  So today to relieve a little tension on the fault and in my kitchen, I'm baking up some Chocolate Earthquake Cookies. Earthquake Cookies are called that because of the cracking on the top of these great chocolate cookies.
