I found this recipe on allrecipes.com and only made two changes: I added one more tablespoon of key lime juice to the glaze, and I included just a little green food coloring to give the cake just a slight lime green hue.

If the speed with which he devoured this cake was any indication, I would say it was a great success! He had about three pieces after dinner, and then I caught him scarfing down a couple more at about 9pm. It was definitely tasty and moist with just the right amount of key lime flavor. This is a keeper for when I need a quick pick-me-up.
