Combine the base: In a small saucepan, whisk together milk, cream, pumpkin puree, maple syrup, pumpkin pie spice, cinnamon, and a pinch of salt.
Warm gently: Set over medium-low heat. Whisk often and heat until steaming, 3–5 minutes.
Do not boil—boiling can cause curdling and a grainy texture.
Bloom the spices: Keep it at a gentle steam for 2–3 more minutes, whisking. This step opens up the spice flavors and smooths out the taste.
Add vanilla: Remove from heat and stir in vanilla extract. Taste and adjust sweetness or spice as needed.
Strain (optional): For an ultra-smooth creamer, pour through a fine-mesh strainer to catch any spice specks or pumpkin fibers.
Cool and store: Let it cool to room temperature, then transfer to a clean bottle or jar.
Refrigerate.
Use: Shake well before each use. Start with 1–2 tablespoons per cup of coffee and adjust to taste.
