Begin by filling a tall glass with crushed ice, leaving about an inch of space at the top.

Slowly pour cold Dr Pepper over the ice until the glass is about ¾ full.

Drizzle 1-2 tablespoons of blackberry syrup into the soda, allowing it to swirl.

In a small cup, combine 2 tablespoons of well-shaken coconut cream with ½ teaspoon of pure vanilla extract and beat until smooth.

Gently pour the coconut cream mixture over the back of a spoon to float it above the soda.

Stir the drink gently with a straw or spoon just before serving.
