Step 1

Add heavy whipping cream, vanilla, and sweetener to a mason jar. Add in any additional flavorings. Secure lid tightly.

Step 2

Shake jar vigorously for about 5 minutes until liquid doubles in size. Set a timer!

Step 3

Place in the freezer for 2 to 4 hours until frozen. If you have any "heavy" add-ins like pecans or chocolate chunks, check the ice cream after an hour or two and give it a good shake to prevent the add-ins from all settling at the bottom.

Step 4

When ready to eat, set the ice cream on the counter for a few minutes to soften. Enjoy!
