How to Make It
Combine cola, ketchup, coffee, molasses, vinegar, Worcestershire, chili powder, salt, garlic powder, and onion powder in a medium saucepan over medium-low. Cook, stirring occasionally, until heated through and flavors meld, about 30 minutes. Remove from heat, and cool completely, about 30 minutes. Transfer to an airtight container, and store in the refrigerator up to 2 weeks.
