The moistest by far is white vs. yellow. And the trick is to bring cupcakes out of the oven just as they start to get slightly golden on top. When in doubt stick in a toothpick. Over cooked cake is the reason for dryness. And you could arrange them on platters to look like a flower. I have done this for paw prints with a small round cake for blues clues. And if I had had a winter wedding I wanted to place 2 candy cane cakes facing each other to form a heart. Just some suggestions.
