Heat the half & half and cinnamon in a saucepan over medium heat. The cinnamon will sit on top until the half & half warms up. Be sure to whisk it frequently to prevent scorching.
As soon as you see steam, turn the heat down to low and let it sit for 5 minutes, whisking frequently.
Remove it from the heat and add the vanilla and sweetener of your choice. I add three tablespoons of honey to this recipe, but you can use any sweetener you like.
Line a fine strainer with a few layers of cheesecloth and pour the cream through it.
Transfer to a glass jar or bottle and store in the refrigerator.
