Idea Thief :: Rainbow Cake In A Mason Jar

I’m obviously awarding cool points to the people at Babble for putting a cake in a mason jar, but make it a rainbow cake and those points multiply to infinity. Is this not the best idea ever? They’ve done this with other types of cake as well and it’s equally as darling. I cannot wait to bake me a cake as fast as I can. Thanks to Modern Parents Messy Kids for the find!
