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.
