This vanilla mug cake is a perfect treat for a long Motzaei Shabbat — or any time really. Who needs an excuse? It’s the dead of winter, a time of year I wish for nothing more than to curl up in my bed and hibernate till spring. But… since that isn’t quite an option, I need to find some way to spark joy on these long, cold nights. As I’ve mentioned before in this column, I believe a real balabusta should have a fresh cake on her counter at all times. The problem is when that cake gets continuously devoured. Mug cakes are the perfect answer. In under five minutes, you’ve got fresh, hot cake with built-in portion control!
