Melt chocolate and sugar together in a double boiler. If you don’t have a double boiler, melt the chocolate in the microwave, then stir in the sugar.
Puree chocolate, sugar and tofu in blender. Add milk as needed to, one tablespoon at a time, to achieve your desired consistency.
Add cinnamon and blend until well combined. Chill in the refrigerator until ready to serve (vegan version). Or, see instructions below for non-vegan version.
Optional
For a more traditional chocolate mousse consistency, beat egg whites to a semi-stiff peak in a separate bowl. Fold egg white into chocolate mousse mixture, being careful not to over mix. Serve or refrigerate until ready to eat.
