You won’t be able to leave this one alone and it won’t last long.  Your family and guests will love it. When you need a delicious cake that is super simple, make this one! We love homemade cakes as much as the next person but sometimes a simple dessert just gets the job done. That is what this cake is! It’s basically a cake mix dressed up. I’ve made this cake for several occasions and it always gets rave reviews! I love a dessert that has a certain “wow” factor but is still simple to prepare and that is THIS cake.
