I am sure everyone has tried the brownies in a cup, but I found this site and enjoy many of the recipes all have turned out. www.biggerbolderbaking.com Mug Meals section.
Thanks for the link. I'm not sure about the mug meals but there are several recipes on that site that I plan to try. I have made many types of mug cakes (being a professional dieter), but they usually are a disappointment.
