Italian Rainbow Cookies Cake

"Italian Rainbow Cookies are such a popular cookie and a staple in most cookie platters. What if you could take that tasty cookie but serve it in cake form? Now you can! Your guests will be so impressed when you cut open this cake and show three beautiful cake layers (and two layers of jam!). The cake is labor intensive, and must sit in the fridge overnight before covering it, but it's worth it. Get the full recipe at Drugstore Divas."
