My mom knows the key to my heart and every time I come home to visit her in Boca it’s waiting there in the refrigerator; a plastic container of my favorite cookies of all time, rainbow cookies, purchased from Bagels With just down the street. They’re not really cookies, more like squares of almond-flavored sheet cake with multi-colored layers, slathered with jam, the whole thing covered in chocolate. I’ve blogged about rainbow cookies before (here and here) but weirdly, I’d never made them. Then, this past weekend, I was having some friends over for their birthdays (four friends, three birthdays) and figured it was a perfect opportunity to try my hand at rainbow confectionary. Only, instead of cakey cookies, I made a cakey cake.
