Preheat oven to 325 degrees. Prepare a pan with a water bath that is deep enough for your chosen ramekins/custard cups.
Whisk together cream, syrup, and pumpkin in a heavy saucepan and bring to a simmer over medium heat.
Whisk together yolks, cinnamon, cloves, vanilla extract, nutmeg, and salt in a bowl.
Add hot pumpkin mixture to yolk mixture in a slow stream, whisking constantly. Pour custard through a fine-mesh sieve into the serving cups, leaving room at the top for the whipped cream.
Bake custards in the dish of a hot water bath pan (I used a Dutch oven to ensure it was deep enough) covered tightly with foil.
Depending on how deep your dish is, cook until the middle is set and does not wiggle. I baked these for approximately 75 minutes with the foil removed for the final 15 minutes. For standard ramekins, the time will be closer to 45 minutes.
Transfer custards to a rack to cool completely. Chill, covered, until cold, at least 2 hours.
To prepare the whipped frosting, combine all ingredients and beat on low with an electric mixer fitted with the whisk attachment until all ingredients are incorporated. Increase speed to medium-high and continue whisking until mixture thickens. Increase speed to high and whisk until cream is thick and develops firm peaks. Do not over-mix, if the cream looks curdled it is over-mixed.
Using an icing spatula (or if you have a whipped cream dispenser), spread the whipped cream onto the pumpkin pot de crème in a circular motion to create a peak. Sprinkle with sparkling sugar and decorate with cinnamon stick. Serve immediately or refrigerate until ready to serve.
Serve cold and enjoy!
