Does anyone have a good recipe for mocha birthday cake?

Epicurious.com has quite a few. Just type "mocha cake" in the search box on their home page.

This is a good recipe for a chococolate chip mocha angel food cake. You could just stick the candles on top and serve with ice cream on the side, or drizzle some chocolate or mocha sauce over the top first.
