Start by chilling your old fashioned glass in the freezer for 5 minutes. This simple step keeps your drink colder longer and prevents the ice from melting too quickly. While you wait, gather all your ingredients and equipment.

Remove the glass from the freezer and fill it completely with ice cubes. Don't be shy with the ice - you want it packed full to maintain that perfect temperature throughout your drinking experience.

Pour the spiced rum directly over the ice, measuring carefully with your jigger. The rum should hit the ice with a satisfying clink, and you'll already start smelling those wonderful spice notes.

Add the coffee liqueur to the glass, pouring it slowly over the rum. You'll see the beautiful dark color start to develop as these two ingredients begin to marry together.

Give the rum and coffee liqueur a gentle stir with your bar spoon, just 3-4 slow rotations. You want to combine them without aggressively melting the ice or creating too much dilution.

Now for the signature layering technique that makes this drink so visually stunning. Hold your bar spoon upside down, positioning it just above the surface of the liquid. Very slowly pour the heavy cream over the back of the spoon, allowing it to gently float on top of the darker mixture below.

Finish with a light dusting of ground cinnamon over the cream layer. For an extra special presentation, add a cinnamon stick or star anise as garnish. Serve immediately while everything is perfectly chilled.
