Not only were these Olympic themed for our Olympics dinner, but they were darned tasty and not so bad for us. A friend served a cake a few weeks ago that was made from a cake mix and a diet soda (no eggs or oil) and it was great! She had made chocolate with black raspberry - I made "funfetti" (to match the olympic ring colors) and diet 7-up. One cake mix, 10 ounces of soda. Bake as usual (I thought it didn't take quite as long, but I was baking at my in-laws so am not so familiar with the oven). Super moist and tasty. Lots of flavor combinations possible too.
