Coffee Mug Carrot Cake - I tried this recipe. It makes a lot though. Next time I would halve it and it would still be a decently large portion. Maybe next time I'd increase cinnamon, replace white sugar w brown.
The berries you see are called "zereshk" in Persian and they should be barberries. This is a very traditional Iranian recipe. Barberries are not easy to find, but for those of you who live in big cities, you should be able to find an Iranian shop.
