<\/a><\/p>\nWe don’t really do St. Patrick’s Day, but I was seeing so many fun rainbow and pot o’ gold crafts, snacks and baked goods on blogs and on Pinterest that I just had to make this rainbow cake. \u00a0I’d originally seen rainbow cakes in layers, which I think is so beautiful and orderly. \u00a0But I do not have enough cake pans of the same size, nor do I have the patience and willingness to make 3 cakes, then wash and dry the pans and make 3 more. \u00a0So I found this rainbow cake on Hostess with the Mostess<\/a>\u00a0who links to Omnomicon’s tutorial<\/a> for making this fun and easy rainbow cake that only requires you to have 2 cake pans of the same size! \u00a0Perfect.<\/p>\n I used the cake recipe from Omnomicon, which is simply 2 white cake mixes and 3 cups of Diet Sprite. \u00a0No oil, no eggs, no joke. \u00a0So I suppose this cake could be considered “good” for you. \u00a0But then I used a not so good for you buttercream instead of the cool whip and pudding frosting that she uses. \u00a0The cake in its entirety is kind of like ordering a diet coke along side your big greasy hamburger.<\/p>\n The cake recipe honestly had me a little worried. \u00a0Was this diet soda thing really going to work? \u00a0Well, it did! \u00a0For the most part anyway. \u00a0The cake took a little longer to bake, about 40 minutes, and even then it was so moist that it fell apart a little after being removed from the pans. \u00a0One layer split almost totally in half, but I was able to squish it back together with the help of a bit of frosting. \u00a0It was also stickier than normal cake mix cakes. \u00a0I let the cakes cool upside down on racks and when I went to take them off I had more breakage because it had stuck to the rack. \u00a0Again, frosting repair was needed. \u00a0Here is but one of my frosting repair jobs.<\/p>\n But even with the problems that made cake assembly a little difficult it was oh so very tasty, moist and delicious. \u00a0I think with cupcakes you could use this cake mix + diet soda method and be quite pleased with the results since you don’t have any layering to do, and there’s less guilt involved. \u00a0I think you might only get 12-18 cupcakes out of one cake mix and 1 1\/2 cups of diet soda. \u00a02 cake mixes and 3 cups gave me what a cake mix with the usual eggs and oil would have. \u00a0But there might be some deflation due to mixing the batter once all together and then again to make the colors. \u00a0I don’t know. \u00a0I am not a scientist.<\/p>\n Dividing and coloring the cake batter was pretty simple. \u00a0I used a scale to get the same amount in each of my 6 bowls, but you could easily eyeball it and not suffer any serious consequences if you were a little off. \u00a0You really should use gel colors if you want the lovely bright colors. \u00a0The food coloring you use for dyeing Easter eggs won’t cut it. \u00a0I used Wilton gel colors<\/a>. \u00a0If you do any cake or cookie decorating at all, you should have some of these.<\/p>\n Grease and flour 2 8-inch cake pans and fill the first pan with red, orange and yellow. \u00a0Pour the red in first, right in the center of the pan. \u00a0Follow with the orange, also right in the center and try your best to make it a circular shape (mine was kind of amoeba shaped) and the do the same with the yellow. \u00a0In the second pan fill with green, blue and violet. \u00a0If you are a science nerd you noticed that I left out Indigo<\/em> from ROYGBIV. \u00a0Feel free to divide your batter into 7 and make yourself some indigo colored batter, but I took a short cut and liked the ease and equality of 3 colors in each pan.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n
