Step 1

For each flavor, start with store-bought or homemade chocolate or vanilla ice cream.

Step 2

Scoop ice cream into a stand mixer, or large mixing bowl if you're using a hand mixer. Using the paddle attachment, blend quickly until ice cream is just soft.

Step 3

While ice cream is soft, mix in fruit, other mix-ins, purees, or candy, then transfer to a container. (To make swirls of hot fudge, caramel or peanut butter sauce, spoon ice cream into a container, layering it with the sauce.)

Step 4

Cover and freeze until solid, about 4 hours or overnight; then serve.
