Iam using Vegan Week as an excuse to introduce you to one of my all-time favorite cakes. Vegan or no, this is the cake you should turn to if you ever have a craving for a damp tea cake fragrant with citrus and sticky with a luscious glaze. Seriously, doesn’t that look good right now, in the dark days of winter? This cake has a double bonus: It takes five minutes to make. Vegan, quick, easy, utterly foolproof and delicious — how can you not try it?
