I usually make many sorts of ice cream by myself. If you know those baking mixes like muffin types, or strawberry cheese cake and those, then you have already the base for delicious ice creams. I sometimes prepare the dough of those cakes, and put it in pieces into the ice cream and stir up. The ice cream is the usual mixture of whipped cream, milk, foam-beaten egg-white, sugar, (maybe a bit butter), and the cream or filling of the cake mix. It works.
