Chill your tools: For the best foam, use a cold bowl or a cold jar and cold ingredients. Pop them in the fridge for 10 minutes if you can.
Combine the base: In a small bowl or jar, add 2 tablespoons heavy cream, 2 tablespoons milk (or half-and-half), and 1 tablespoon pumpkin puree.
Sweeten and season: Add 1 to 2 teaspoons maple syrup (or brown sugar), 1/4 teaspoon vanilla extract, 1/4 teaspoon pumpkin pie spice, and a tiny pinch of salt.
Froth it up: Use a handheld frother for 20–40 seconds until thick and creamy.
No frother? Shake vigorously in a sealed jar for 45–60 seconds, or whisk by hand for about 1–2 minutes.
Adjust to taste: Taste and add more spice or sweetener if needed. If it gets too thick, splash in a little milk and froth again.
Serve: Fill a glass with ice and cold brew or iced coffee.
Spoon or pour the pumpkin cold foam on top. Dust with a little extra pumpkin pie spice if you like.
Optional cold foam finesse: For a sweeter finish, drizzle a touch of maple syrup around the inside of the cup before adding the coffee.
