Sweet Potato Pound Cake

Step 1
Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 10-inch tube pan. Sift together flour, baking powder, cinnamon, baking soda, nutmeg and salt. Set aside.

Step 2
In large mixing bowl, cream butter and sugar until light and fluffy. Add mashed sweet potatoes and vanilla. Beat until well blended. Add eggs, one at a time (the batter will look curdled). Add flour mixture to potato mixture. Beat on low until combined.

Step 3
Pour batter into 10 inch tube pan. Bake at 350 degrees F (175 degrees C) for about 1 hour and 20 minutes, or until a wooden toothpick inserted into cake comes out clean. Cool cake for 20 minutes in the pan, then invert onto serving plate.

Step 4
To make the glaze: in a small bowl, combine confectioners sugar with 3 to 5 teaspoons orange juice to achieve drizzling consistency. Spoon over warm cake and sprinkle with orange zest if desired.
