Classic rainbow layer cake
Featured on Whisk Kid, it doesn't get much better (or more colorful) than this epic rainbow birthday cake that gives Rainbow Brite a serious run for her money!
Made out of colorful layers of cake with a lemony Swiss meringue buttercream, Whisk Kid Kaitlin recommends using gel food coloring rather than liquid to achieve the vibrant colors in this tall rainbow-rrific cake. Check out the rest of the post for the full recipe — there's also a link included for when Kaitlin made this cake on The Martha Stewart Show (wow!), and a fun time-lapse video of this cake being made by one of Kaitlin's readers.
