In a mixing bowl, whisk together heavy cream, pumpkin puree, maple syrup, vanilla extract, ground cinnamon, and ground nutmeg until smooth and well combined.
Fill a glass with cold brew coffee.
Slowly pour the pumpkin cream mixture over the cold brew coffee, allowing it to swirl beautifully.
Add ice cubes for an extra chill if desired.
Top with a dollop of whipped cream and a sprinkle of ground cinnamon for garnish.
Serve with a straw or spoon to mix in the flavors to your liking.
