Heavenly Blueberry and Cream Angel Dessert

"So here's the deal, it depends on what type of angel food cake you are using to determine how much of it you need. You need about one angel food cake. According to my Aunt Marilyn, a storebought angel food cake is the perfect size. I made this while my mom was visiting; she made an angel food cake from a cake mix and we used almost all of it in the dessert (minus the amount that exploded in my oven and the pieces we snacked on - so I'd say we used 3/4 of the cake). I'm guessing that my homemade angel food cake recipe would be just about perfect since it is slightly less tall than a cake mix angel food cake. Basically, just keep an eye on the cream/cake mixture - only add cake cubes while they are all evenly coated with a thick layer of cream. Too many cake cubes and it might dry out (especially if it is made in advance). Speaking of making it ahead, this can be assembled and refrigerated up to 24 hours in advance...."
