Chocolate Potato Cake

Putting vegtable in a cake may sound a bit weird but it worked for carrot cake and the addition of mashed potato makes gives this cake a delightfully moist and smooth texture. Despite the vegtables I would not go as far as to say it is healthy, but it can't make it any worse for you at least.

125g chocoalte
