In a shallow dish mash 1 cup of the blueberries with a potato masher. (Or puree with a mini food chopper, food processor, or blender.) Stir cinnamon into mashed blueberries.
In a medium bowl beat whipping cream and sugar until cream is very thick. Fold in mashed blueberries.
In individual 6- to 7-ounce glasses or dishes, layer whipped cream mixture with remaining blueberries and kiwifruit. Serve immediately or cover and chill up to 2 hours before serving. Makes 6 servings.
