Brew your coffee as you normally do. PLEASE NOTE that if you are adding cinnamon to the grounds during brewing, you MUST have a paper filter machine. Other types will get clogged by the cinnamon.
Allow it to cool a bit (at least 10 minutes or more if needed!). SUPER HOT COFFEE WILL MAKE YOUR BLENDER EXPLODE! Seriously. Let it cool a little.
Transfer warm coffee to a blender and add the rest of the ingredients.
Blend for about 1 minute or until the oil is well integrated into the coffee.
Serve with a small sprinkle of cinnamon or unsweetened cocoa powder on top.
This does NOT work with cold coffee.
