In a large saucepan, cook cola over medium heat, stirring occasionally, until reduced to ¾ cup and slightly thickened, about 1 hour, adjusting heat as needed. Let cool completely before using.
Notes
Kitchen Tip: Cola Syrup can be refrigerated in an airtight container for up to 1 week. Microwave it just to take the chill off, 10 to 15 seconds, before using.
