Coconut doesn't have to be the primary ingredient in cakes; it can also be used to lend its own brand of sweetness and goodness to all manner of baked goods, such as this glorious Bundt cake. Besides, coconut goes well with so many different flavors, including the oranges that give this treat its heady fragrance. Using a combination of regular and whole wheat flour, and adding yogurt to the batter, makes for a more wholesome dessert.
