I have been making a lemon cake with Diet 7 Up. Just mix the pre-packaged lemon cake with 20 oz of Diet 7 Up, pour into a 9x13 pan and bake at 350 for 30 minutes. The cake is quite sticky and I find keeping it cold not only makes it easier to manage, but makes it taste better too. It's pretty good by itself, but a little lemon yogurt on top REALLY makes it a treat! As far as nutrition, if the entire cake is divided into 12 pieces, each serving is 240 calories, 3g of fat, 34g of carbs, and 2g of protein.
