  1. You could also do two smaller coffee-cups worth of cake, in which case you will want to reduce the baking time. ↩︎

  2. This, and limiting the time in the microwave, is the secret to a moist cake. ↩︎

  3. Depending on your microwave, start checking at 45 seconds. The cake should rise, look set on top but still be moist on the inside. ↩︎
