I will be making a boxed Angel Food Cake which will be offered as dessert after a light lunch. I want to frost it with something easy, thinking of Cool Whip. I will be placing a small vase in the center of the cake and putting in some fresh edible flowers for decoration and presentation only. I think after cutting the wedges, of serving it with slightly sweetened strawberries. Any ideas on what else I could frost it with? Also, can I add any type of berries, or lemon zest, or ? to the boxed mix without fear of failure? Ideas please......
