01 - Brew the coffee to your preferred strength and pour it evenly into two heatproof glasses or mugs. Stir in the brown sugar and vanilla extract until fully dissolved, ensuring a homogeneous mixture.
02 - In a separate, small bowl, lightly whip the cold heavy cream. Continue whisking until the cream begins to thicken and holds soft peaks, yet remains easily pourable for layering.
03 - Carefully pour the prepared cream over the back of a spoon. This technique allows the cream to gently float and create a distinct layer atop the coffee mixture in each glass.
04 - As an optional final touch, sprinkle a pinch of ground cinnamon, nutmeg, or a few shavings of dark chocolate over the cream layer. Serve the mocktail immediately, encouraging guests to sip the coffee directly through the creamy topping.
