Two out of the three tasters loved the cupcakes. One of the girls didn't care too much for the frosting - She felt it was a bit too sweet, but she did enjoy the cupcake. I found this recipe on one of my new favorite blogs. I started making the cupcakes and realized I didn't have enough white sugar. So I added 1/4 cup of light brown sugar in place of the 1/4 cup of white sugar I was missing. I think this added a nice caramel flavor to the cupcakes and I will definitely use brown sugar next time I make these. I may even bake the sweet potato instead of steaming. I think this will add great flavor.
The recipe is fairly easy. The only part that could be tricky is the brown butter. The recipe doesn't explain how to brown butter so here's a link which shows how to brown butter (it's really not very difficult, even for a beginner cook). How to brown butter
Sweet Potato Cupcakes with Brown Butter Cream Cheese Frosting
Steam the sweet potatoes until fork tender, about ten minutes. Set aside to cool slightly then mash with a fork until smooth. In a medium bowl cream together the butter and sugar until light in color, about three minutes. Add the egg, sweet potato, buttermilk, and vanilla. Mix until well combined.
In a large bowl sift the flour, spices, baking powder, baking soda, and salt together. Pour the wet mixture into the dry and whisk until no large lumps remain. Do not over-mix.
Divide the batter evenly between the baking cups. Bake for 18 to 20 minutes, or until the cakes are golden brown and spring back when lightly pressed in the enter. Cool for three minutes in the pan then remove the cupcakes to a wire rack to cool completely.
