Pour the chilled cola into a shallow dish or container and freeze for at least 4 hours, stirring every 30 minutes to prevent large ice crystals from forming.
Once the cola is frozen into a slushy consistency, transfer it to a blender along with the ice cubes.
Blend on high speed until the mixture is smooth, frosty, and resembles a thick slushie with a bubbly appearance.
Pour the icy mixture into glasses immediately to enjoy its refreshing texture and fizzy flavor.
Optional: garnish with a slice of lemon or a cherry for added visual appeal.
