Add Kahlua to the halfway point. Slowly pour in the cream; for best results, pour the cream in off the back of a cocktail spoon.
Stir just before enjoying.
Notes
When pouring the cream, aim for a slow and steady stream. Pouring the cream off the back of a cocktail spoon helps distribute it gently and evenly over the Kahlua, creating a smooth and visually appealing layered effect.
