When the ice cream base is cold, transfer to your ice cream machine and churn for 15-20 minutes, until thick and creamy. In a sealable, freezer-safe container, layer the ice cream: ice cream, streusel, ice cream, peach jam, etc. Once in the container, transfer to the freezer to set up, at least 2 hours (you can eat it right after churning, but it is very soft!).
