Domestic Goddess Redux--Pain-Au-Chocolat Bread Pudding

This dish is impressive and easy. If you don't have pain au chocolat, cut croissants from Costco in half, and put chocolate chips in the middle. Use the Costco croissants, as they are the only local ones made from butter. From How to Be a Domestic Goddess by Nigella Lawson.

Pain-Au-Chocolat Bread Pudding
3-4 stale pain au chocolat
2 1/4 cups milk
2 1/4 cups heavy cream
3 Tbsp. sugar
1 large egg

4 large egg yolks
1/2 tsp. vanilla extract
 Preheat oven to 325F.
Butter a 6-cup ovenproof dish, cut up the pains au chocolat--I cut rough slices of about an inch--and arrange them in the dish. Put the milk and cream into a pan and bring near to boiling. Whisk the egg, the yolks, and the sugar in a large wide-mouthed measuring cup. When the milk and cream are nearly boiling, pour over the eggs and sugar, whisking continuouly. Add the vanilla and then pour over the slices of pain au chocolat and leave to soak for 10 minutes.
Transfer to the preheated oven and cook for about 45 minutes, or until the pudding is softly set.
