Add 1 cup of coarsely ground coffee to 3 cups of water into a container like a mason jar, put the lid on, and let it sit overnight. In the morning, stir and strain the contents with a fine-mesh sieve and you’re ready to top with pumpkin foam and serve.
If you don’t have a sieve but have a paper coffee filter, just pour the steeped coffee into the paper filter, and let the liquid drain into another container.
To make pumpkin sweet cream:
To a frother, add the heavy cream and milk with brown sugar. Add the pumpkin puree and pumpkin pie spice.
Froth for about 30 seconds or until you achieve your desired thickness. If you don’t have a frother, then blend it.
To serve, fill a glass with ice, add the cold brew, and spoon on the pumpkin foam. Enjoy immediately.
