I decided to bring back the rainbow cake for another birthday this month. This one was a little different than the traditional cake a prepared a few weeks earlier.
You will need:
1 box of white cake mix (eggs, oil, and water)
1 can of cream cheese icing
8 half pint mason jars
1 9″x13″ pan
5 small bowls
5 food coloring gels ( I used red, yellow, green, blue, and purple)
Preheat your oven to 350 degrees. Take your 8 mason jars and wash them thoroughly. Now dry them off completely and spray the inside of the jars lightly with a non-stick cooking spray.
Follow the cake instructions on the box to prepare your batter.
Then take the 5 small bowls and fill them up with even amounts of batter to get the ready for coloring. Next add a specific color to each bowl and start mixing. Be careful, if you add too much food dye you may be able to taste it later. Once you have achieved your desired shade it is now time to start layering the batter.
Start by filling the jars with about a 1 1/2 tbsp full of purple batter. Next add the blue batter keeping a nice, somewhat even layer on top of the purple. Add the next colors using the same technique. I like to layer my colors purple, blue, green, yellow, and red but you can layer them in whatever order you want. :)
After you are done filling up the 8 jars, add about a 1/4″ inch of water to a 9″x13″ pan and place all 8 jars inside.
Bake in oven for about 35 to 40 minutes or until top of cake bounces back after touching or a toothpick inserted comes out clean.(If you feel your cake is not done leave it in there for an extra 5 minutes. Keep a good eye on it though. You don’t want to over bake these little ones.)
When the cakes are done let them cool for about 20 minutes. (I like to let them cool this long because the jars are usually still warm to the touch after 10 minutes.)
Time to frost!
If your cake has risen too much out of the jar that is quite all right. Just simply scoop some of the cake out and clean the edges. Now you have room for some frosting.
Take your can of frosting and dye it whichever color you wish…or don’t. (I chose yellow because it’s a bright color.) Mix the frosting and the dye together to get your desired shade. Scoop heaping tablespoons into the jars and swirl them around. Next add a few sprinkles while the frosting is still soft.
Stand back and admire! You’re all done!
I hope you like it and have fun baking!
