Chill a large metal bowl in your freezer for at least 30 minutes before getting started.
Once the bowl is chilled, add the heavy cream and yogurt to the bowl; whisk well.
Add the granulated sugar and continue to whisk until fully combined and no longer grainy. Stir in the coconut extract. Fold in the toasted coconut.
Transfer the mixture to a large freezer safe container or bowl. Cover and freeze overnight. Alternately, you can chill the mixture and then process in an ice cream maker.
Sprinkle with additional toasted coconut for garnish when serving.
Notes
How to Toast Coconut: Heat the oven to 350°F. Spread the coconut evenly on a baking sheet. Bake for 7 to 8 minutes or until light golden brown, stirring occasionally.
