Another good topping or filling is to mix a 4-serving box of instant pudding with 1 1/2 cups of milk. When set, fold in a small tub of whipped topping (the size that's usually on sale for around $1 during the holidays). Serve with the cake slices. Vanilla flavor, lemon, or chocolate are all tasty. Lemon appeals to me today, but I don't have any angelfood cake on hand, lol.
