Fill a tall glass with ice cubes to keep the drink cold
Pour coconut syrup over the ice, letting it settle at the bottom
Add blackberry or cherry syrup for that rich, dark swirl effect
Slowly pour chilled cola into the glass to create layers
Add lime juice for a fresh, tangy balance
Pour in Malibu rum if using, keeping the layers intact
Gently drizzle heavy cream over the top to create a swirling “dirty” look
Stir lightly if desired or leave layered for presentation
Garnish with a cherry and serve immediately
