ever since i saw the rainbow cake of cake shack, i knew i had to try it. light, fluffy, colorful layers of buttercake with a cream cheese frosting. i initially wanted it with rainbow colored icing but other than the price, i realized that the colorful layers will not shine through if the icing is multi colored as well. luckily, there's an option to have a colored icing other than the traditional white one. got mine in yellow which was perfect. it was really good and you can see the brightness of the colors which other rainbow cakes out there fail to match (if they google they will know why their layers are not bright and colorful!). this was my birthday cake by the way hehe...good enough reason to buy a big cake isn't it?
