Thank you! I tried to make a mug cake before but it did NOT turn out right. I think it was the egg, because a whole egg in that amount of cake is just too much. Anyway, here's a picture. It was pretty inflated when I took it out of the microwave, but by the time I snapped the picture it had deflated. It looked like a slug!

(Going to try to embed but last time I tried that on journalfen it didn't work for some reason.)
