Agree about the price. Just the cream and condensed milk will cost over $6 and really only makes 1l of ice cream (though it's aired up volume wise a bit). You can get Peters 2l for $5.50.

It's definitely more of a novelty/specialty thing to do.

If you want another fun dessert, that's not quite so minimal effort as the ice cream, have a look around for Chocolate Eclair cake recipes. It's fun, and no cooking required. It's basically, biscuits, whipped pudding/cream, and some choccy icing. Again will probably cost $10 all up, but it's pretty damn good for low effort - and not even turning on an oven! The hardest part is the waiting .... 😋
