at most coffee chains (starbucks, dunkin) the seasonal drinks contain milk, so heres how to make a yummy pumpkin spice latte at home:

ingredients:

1. hot coffee (approx. 6 ounces)
2. 1/3-1/2 cup soy milk (or other milk substitute)
3. 3 table spoons canned pumpkin
4. 1/4 tsp vanilla extract
5. a packet of sweetener (or tbsp of sugar or agrave)
6. dash of cinnamon

mix the canned pumpkin into the hot coffee and stir throughly, then add the soy milk (heat it before hand), and then mix in all the other ingredients and sprinkle cinnamon and nutmeg on top if you like. you can also mix a tsp of cocoa powder in to make it a mocha pumpkin latte :)
