Instructions:
Make caramel by slowly heating the sugar in a small saucepan until golden and liquid. Be careful not to stir too much, as this will cause crystals to form. Pour the very hot, molten sugar into the mold. Be sure to tilt the mold so that the caramel coats the sides.
In a small saucepan, heat the milk, cinnamon, and chocolate pieces, stirring occasionally to help the chocolate melt. Remove the cinnamon stick. Let this cool down to just warm. Blend the rest of the ingredients together gradually adding the milk mixture.
Pour into caramelized pan and bake at 350ºF in a hot water bath (bain marie) for about 45-50 minutes or until golden. Test with a knife or toothpick, it should come out clean. Remove from oven, cool and serve.
