Sweet Potato Cake

I began my love affair with the sweet potato sometime in September, a few weeks after I found I out I had Diabetes. Not only is the sweet potato a nutritional dynamo (it's high in fiber, Vitamins A & C, and betacarotene) but it has the lowest glycemic index of all the root vegetables. Sweet potatoes have a variety of applications, but most of my favorites fall into the savory category. The naturally occurring sugars in the sweet potato however, lend themselves well to desserts, such as traidtional sweet potato pie, so why not bake it in cake? I used my favorite butter cake recipe and adapted it slightly to accommodate the addition of mashed sweet potatoes. This cake is moist and dense, but surprisingly light feeling in your mouth, and just sweet enough from the addition of maple syrup.
sweet potato cake (2)

1 cup butter, softened
2/3 cup white sugar
2/3 cup brown sugar
3 eggs
1 teaspoon vanilla extract
2 cups all purpose flour
1 cup cake flour
1 tablespoon baking powder
1 teaspoon kosher salt
1 1/3 cups milk
1 medium sweet potato, peeled, cubed, boiled, and mashed.
1/3 cup maple syrup

Cream the butter and sugars in an electric mixer until light and fully combined. Add vanilla and eggs, one at a time, incorporating completely after each addition. Let egg and butter mixture blend until very light in color, about 4 minutes on medium/high speed.

In a separate bowl add the flours, baking powder, and salt and whisk to combine.

In a large measuring cup, measure the milk, add the mashed sweet potato and maple syrup and stir to combine.

When the butter mixture is light and fluffy, add 1/3 of the flour mixture and mix well. Add 1/2 of the liquid ingredients and stir. Repeat with remaining flour mixture and liquid mixture, making sure to end with the dry ingredients. Make sure to scrape down the sides of the bowl when giving it a final mix.

Pour the batter evenly between two 9 inch round cake pans that you've buttered and floured. Tap the pans lightly on the counter to remove any air bubbles and bake in a 350 degree oven for 40 to 50 minutes, or until a toothpick inserted in the center comes out clean.

Cool cakes in their pans for 15 minutes, then turn out on to wire racks to cool completely.

When cakes are completely cool, frost with Cream Cheese Frosting, and decorate the sides with chopped walnuts.

    tried this recipe tonight. It really needs a boost in sugar. I felt like it wasnt sweet enough and reminded me of a biscuit. I didnt use creamcheese frosting but i might to give it the sweet-ness it needs.

    The cake was very soft and light. Just ashame it wasnt sweet enough. Thanks for the recipe though!

    I never think that sweet potato can turn into a great baked cake. I usually have them in my pancake which is completely different with cake. Thanks for the recipe. I think it is worthy to try.
