Boston Cream Pie Cake. I made this for Mother's Day and it was super-easy and turned out delicious (looks spectacular on a pretty cake plate, too)! I used a plain, bakery-made angel food cake and substituted whipped heavy cream for Cool Whip. I also added a few drops of half and half to make the chocolate easier to work with. It only takes a few minutes to make this way. Then I chilled it a couple hours before serving, but you don't have to. Rave reviews!
