1 cup milk heated to very hot
2 - 3 tsp cocoa (I do 1 tsp of dark ground chocolate - you could easily use a little chunk of a good quality dark chocolate here)
1 tsp corn starch or rice flour (make sure your rice flour is very finely ground - some of the natural food store's versions have grit to them and this does not soften.)
2 packets of sugar replacement of your choice
1/4 tsp of an extract of your choice
pinch of instant coffee
pinch of cinnamon
Mix together, and microwave the finished mixture to reach a nice temperature. The starch thickens the end result to make it seem like you're using cream.
