This easy dessert recipe is a layer of cake topped with a layer of flan. Of course, there’s drippy caramel sauce involved as well. Now you don’t have to choose between cake or flan — you get the best of both worlds! This is one of my favorite Puerto Rican desserts it is also called flancocho, or flan cake. In Puerto Rico, bizcocho is the Spanish word for cake. Whenever I go to a party and someone walks in with flancocho, they are my new best friend!
