This drink is similar to Irish coffee in its delectable creaminess. For best results, use strong coffee.
In a medium saucepan over medium heat, bring the water, sugar, and cardamom to a simmer, stirring to dissolve sugar; turn off heat. (Syrup mixture can be refrigerated in an airtight container up to 1 week. Before using, gently reheat.)
When ready to serve, whip cream to soft peaks. Add brandy and hot coffee to saucepan with syrup mixture, and stir to combine. Divide among four glasses, and top each with a generous dollop of whipped cream. Serve immediately.
