It’s portable. It’s easy to make. It’s tasty. And it’s RAINBOW. No wonder rainbow cake in a jar is becoming so popular! Behold, the ideal birthday cake to bring to school.

First of all, it almost doesn’t even look like cake — it looks like someone magically captured sunshine and happiness in a jar and topped it with fluffy whipped cream and pixie dust sprinkles. At first glance, you just want to sit and stare at its beauty. Then you realize that it’s edible, too!

If you’ve ever tried to bake a boring funfetti cake for a friend’s birthday and bring it to school, you’ve probably run into the problem of carefully carrying it around campus. If your cake is in a small glass jar, you no longer have to fear dropping the precious cake, creating a huge sugary mess, and ruining your hungry friend’s birthday.

You also don’t have to be paranoid that food-crazy Marlborough scavengers will steal any of your cake. A normal cake, protected only by a flimsy sheet of plastic cling wrap, will inevitably fall prey to ravenous passersby. This fate can be easily avoided: the jar’s thick glass walls shield your culinary creation from the greedy hands of cake thieves!

To quote Mean Girls, don’t you just wish you could bake a cake full of rainbows and smiles, and we’d all eat it and be happy? Well, now you can, in just a matter of minutes. Instead of wasting precious homework time by attempting to recreate something you saw on Cake Boss, you can make a multicolored masterpiece in only a few simple steps.
