Some unexpected cake ingredients are hard to pick out if you didn't know it was included in the recipe. Tomato soup adds some moisture to the cake as well as a beneficial burst of antioxidants. It works well as a complementary ingredient in cakes that feature cinnamon and clove to add a nice spicy element. But if you don't want to add salty to the sweet, you may want to use a low sodium base.
