1. Preheat the oven to 325° F.
2. Butter a 1 1/2 or 2 quart casserole dish.
3. Break the chocolate into pieces and melt it in the milk, stirring until smooth.
4. Add the bread to the milk and set aside to cool.
5. When lukewarm, add the remaining ingredients and mix well.
6. Pour the mixture into the casserole dish.
7. Bake uncovered until the center is set. Start checking it at 50 minutes and then at 5 minute intervals after that. It will probably take about an hour.
