Wow, I've been making a lot of treats lately!! I saw the recipe for this cake on omnomicon when I was making the rainbow cake a little while ago. I just used a regular white cake for that, but still wanted to give this lower calorie version a try.
All you do is dump a can of a carbonated beverage (I actually used raspberry flavored, carbonated water) into a white cake mix and bake it according to the directions on the box. It was really easy. I think it was originally listed on the Weight Watchers website. If you use carbonated water like I did, there are absolutely zero calories except what the mix already contains.
THE FINAL REVIEW: This isn't really a "wow that's amazing" kind of dessert. I could have frosted it (Omnomicon also has a low-cal frosting) to give it a little somethin somethin, but I don't really like frosting anyway. It is, however, a good alternative for dessert if you're on a diet or trying to watch your caloric intake. It's not a healthy food, but it is a healthier option than, say, this cake (which I've made twice now and can't keep it around long enough to get pictures to blog about it...it really is that good). Even though the carbonated water I used had a raspberry flavoring, It didn't taste much like raspberries. The cake definitely holds its own flavor. It was okay, but since I'm not that obsessed with the calories I'm eating, I probably won't make it again.
