In a large mixing bowl, pour in 2 cups of Orange Crush soda and add 1 cup of sweetened condensed milk. Stir until smooth, about 2-3 minutes.

In a chilled bowl, whip 2 cups of heavy whipping cream using an electric mixer on medium speed until stiff peaks form, approximately 3-5 minutes.

Gently fold the whipped cream into the orange and condensed milk mixture, ensuring no visible white streaks remain.

Transfer the mixture into a freezer-safe container and spread it evenly. Freeze for about 4 hours, stirring every hour for the first 2-3 hours.

Allow the sherbet to sit at room temperature for 5 minutes before scooping. Serve in bowls or cones and garnish as desired.
