For the Café de Olla:

Combine the water, spices, and sugar in a small saucepan. Bring slowly to a boil over medium heat, stirring occasionally to break up the sugar. Reduce the heat and simmer gently, without stirring, for 30 minutes. Remove from the heat, stir in the coffee, cover, and steep for 5 minutes. Line a sieve with a coffee filter and strain the coffee through it. Serve hot or, for iced coffee, store in the refrigerator, covered, for up to 1 week.

Chill a 12-ounce glass. Drizzle the inside of the glass with the chocolate syrup, then fill the glass with ice and pour in the liquor. Top up with chilled cafe? de olla. Drizzle the cream on top (or spoon on the whipped cream) and dust with cinnamon.
