This mousse has such a smooth and creamy texture, one bite will not be enough.
-For dairy free version, if using semi-sweet chocolate ensure it does not contain milk products.
-Because this is such a rich dessert, I would recommend serving sizes of no more than 1/4 cup (or even shot glasses - that would be perfect!).
-Instead of coffee you can use any milk alternative, like almond, rice or coconut milk (just make sure its hot).
