Today was the Queen Bean's 2nd Birthday. It was such a bitter sweet day for me, since I was both happy and saddened that our little girl is no longer a baby. A while back, there was a bunch of talk about rainbow cake, on many of the cooking forums I follow. As soon as I saw how neat the cake looked, I knew I wanted to make something similar for Queenie's birthday. So I went to work and it turned out wonderfully. I've yet to find a really amazing white cake recipe, so I used boxed mix. My intention was 4 colors, but I quickly realized that my pan would not hold 2 cake mixes. So I did 3 instead and used the leftover batter to make orange cranberry muffins. My mother in law and sister in law really loved the cake and I thought it was pretty darn neat too.
Sunny Day Rainbow Cake
2 boxes white cake mix
24 oz of clear diet soda (2 cans, ginger ale and sprite work well)
gel food colouring
16 oz whipped topping
2 oz instant fat-free sugar-free pudding mix (2 smallish boxes)
Mix the cake mix with the soda according to regular instructions on box. It will be lumpy afterward. Again, you can use any white cake recipe you want, this is just how I do it.
Measure the total volume (by my estimate, 64 oz), then divide by 6 and measure into separate bowls. There are 8 oz in a cup, so 64/6 = 10 to 11 oz, or 1 cup + 2 tbsp.
Stir colour into each bowl with its own spoon. For the first colour into the pan, measure out 2/3 to 3/4 of your mix (in this case about 1 c) as close to the middle as you can. Drop in your first three colours, then work on the other pan with the last three colours. So if you’re doing rainbow order, the first pan should have red, then orange, then yellow, and now the purple, blue and green go into the second pan. As a recap, this is so both layers are roughly the same size.
Bake the cake for however long the box tells you to bake it. Check it when the box says to, but usually it’ll need an extra 5 or 10 minutes or maybe more because of the density of the soda method. Just keep baking, checking back every 5 minutes or so until a toothpick to the center comes out clean. Let cool completely before moving to a wire rack.
Meanwhile, make your frosting. Just mix the pudding mix in with the whipped topping for a few minutes. Dye if you’re into that. Frost your fat-free cake with your fat-free whipped frosting. Eat.
Cindy's notes: I made the cake according to the box directions and portioned the batter into 4 since I had a huge Elmo cake pan. I also didn't use the frosting recipe, but used canned frosting. So I basically just used the concept of the recipe, LOL.
