I think this recipe is good for satisfying a chocolate brownie/cake craving. It's cheaper than buying a baked good, and since it only makes one (or two) servings, it's economical as well (not having to make a large cake just to satisfy a one-day craving).
The cake comes out a bit dense. Texturaly more closer to a light brownie than a cake.
I used a 6" tall tapered mug, It expanded the full height whilst cooking, but shrunk down to 4" once the cooking process was done. The cake really shrinks away from the sides of the mug so itll fall out easily.
I made this without adding any chocolate chips and don't think it's too chocolatey as is, but chocolatey enough.
