1. Make your flavor base:
Add the pumpkin, brown sugar and spices to a small saucepan. Cook over Med-Low heat stirring frequently with a spatula until sugar is completely dissolved, 2 to 3 minutes. It'll look kind of gross.
2. Add your milk in:
Slowly pour your 1 cup of milk choice into the saucepan to your flavor goop. Whisk constantly to smooth out mixture. Continue to cook over Med-Low heat until milk barely reaches a simmer. Remove from heat.
3. Transfer to your blender:
Pour your 1 cup of hot coffee into your blender. Then transfer your flavor mixture from the saucepan to the blender. Add in the vanilla (if you haven't already done that).
Then blend!! I used the "soup" button on my Blendtec, which made a really creamy and frothy drink! Pour in a mug, garnish with more pumpkin spice on top if you'd like and enjoy!
