Perfect for hassle-free entertaining, the ice-cream mixture is made a day in advance, leaving only the churning and assembly for the day. The cookies can be made a day ahead, too. The ice cream needs a good 4–6 hours in the freezer after it has been churned, so take this into account when you plan your to-do list. It will seem like a lot of mint to use, but it’s correct, and gives an amazing depth of avour! The ice cream is also fantastic on its own.
