Ice cream is a semi frozen custard. A custard is egg yolks gently cooked with a liquid. So you should be able to all sorts of ice cream type concoctions that are primal.
My wife makes a banana ice-cream and has made an almond ice cream. The banana ice cream is roughly:
Blend two egg yolks, a banana and 270ml of coconut cream. Heat until it coats a spoon and you can make a clear line in it by drawing your finger across it (I forget the term). Cool and throw it in an ice cream maker.
