Step 1

To make basic mason-jar ice cream: In a clean, wide-mouth mason jar, combine the heavy cream, cream cheese, sweetened condensed milk, sugar, vanilla extract, and salt. Insert one whisk into an electric hand mixer. Beat the ingredients until smooth and thick. Avoid overmixing.

Step 2

To make cookies-and-cream ice cream: Fold in the crushed Oreos to the prepared ice-cream base. Secure the lid, and freeze for 4 hours.

Step 3

To make chocolate Nutella ice cream: In a clean, wide-mouth mason jar, add the ingredients for the ice-cream base except for the sugar. Add the Nutella, beat until smooth and thick, then fold in the brownie chunks and chopped nuts. Secure the lid, and freeze for 4 hours.

Step 4

To make strawberry-cheesecake ice cream: In a food processor, puree 1 cup strawberries. You can leave chunks of strawberries, if you'd like.

Fold in the crushed graham crackers, white-chocolate chips, and diced strawberries, then secure the lid and freeze for 4 hours.
