To Make the Pumpkin Cream Cold Foam
In a medium sized bowl, whisk together the heavy cream, cold milk sweetened condensed milk, kosher salt, pumpkin puree, pumpkin pie spice, and vanilla until smooth. The spice won't mix in completely and that is perfectly okay.
Pour into an airtight container, cover, and keep in the fridge until ready to use.
To Make the Cold Brew Coffee (optional)
Mix the coarsely ground coffee beans and water together in a large container with a lid. Give it a really good stir to soak all the coffee grounds, cover, and place into the fridge or leave on the counter top overnight.
The next morning, strain the coffee into a serving container or large measuring cup through a coffee filter in a mesh sieve.
To Make the Pumpkin Cream Cold Brew
In a tall glass with ice, pour in the strained cold brew coffee.
In your blender or with a milk frother, whip the cold pumpkin cream until thick and just barely giving you soft peaks.
Top your iced cold brew coffee with a generous amount of the pumpkin cream cold foam, then garnish with a sprinkle of pumpkin pie spice over top.
Serve cold and frothy.
