The richness of sweet potatoes makes them a perfect autumn and winter treat. The ones in this particular recipe have maple cream cheese frosting that is topped with a dash of cinnamon, for both color and flavor. The cupcakes themselves are made from a mixture of sweet potatoes (of course), flour, cinnamon, ginger, cloves, sour cream, vanilla extract and several other ingredients. Altogether, these treats are great on a cool winter day!
