Whisk well until all the ingredients are fully combined and the sugar is dissolved.
With the ice cream maker turned on, pour the heavy cream mixture into the frozen bowl. Allow the ice cream maker to run for about 20 minutes, or until the ice cream is a soft-serve consistency.
Scoop the ice cream into a freezer-safe container, and freeze for 4-5 hours or overnight.
Serve in a waffle cone or bowl with a dash of extra cinnamon on top.
Notes
Put the bowl of your ice cream maker in the freezer the day before, to ensure it is fully frozen when you are ready to make the ice cream.
