Combine peaches, orange juice, and sugar; cook over medium heat until sugar is dissolved, stirring frequently.
Pour mixture into freezer can of a 1-gallon hand-turned or electric freezer. Freeze according to manufacturer's instructions. Serve with a dollop of whipped cream, if desired.
Note: 2 (16-ounce) packages of frozen sliced peaches, mashed, may be substituted for fresh peaches.
