Put aside all your opinions of fruitcakes. These are the most delicious, orange flavored light cakes that are full of moist pieces of candied cherries, pineapple and golden raisins. These make great gifts for neighbors and friends if you can bear to part with them. They can be wrapped in plastic wrap and foil and frozen if you want to make them ahead. Frost them with the white chocolate ganache after thawing them.
Preheat oven to 350 degrees. Butter and flour 12 mini-loaf pans or two 9 inch loaf pans depending on how large you want the fruitcakes.
After the cakes are completely cool, make the white chocolate frosting. In a large, heatproof glass measuring cup, microwave the remaining 2 cups of white chocolate chips and heavy cream for one minute. Stir the mixture and heat again for 20 seconds. Stir until the chips and cream are smooth and all the chips are melted. You can microwave the mixture for 5 seconds at a time, stirring just until the chips are melted.
Pour the frosting evenly over each of the cooled fruit cakes and decorate each one with halved red cherries and quartered green cherries to look like holly, if desired.
