Chocolate Babka Bread Pudding

Here is something I made way back at Boxing Day. Everybody loved it and I hope you will too!
Here is the recipe:

Chocolate Babka Bread Pudding
Serves 8-10 people

Butter, for pan
1/2 loaf of challah, at least 1 day old
1/2 loaf of chocolate or cinnamon babka, at least 1 day old
8 eggs
3/4 cup of sugar
2 cups of whole milk
1 cup of heavy cream
1/4 teaspoon of cinnamon
Pinch of salt

Heat oven to 350 degrees. Butter a deep 9 by 13 inch baking dish or disposable foil pan. Cut the challah and babka into cubes, about 1 inch square.

In a very large bowl, whisk together the eggs, sugar, milk, cream, cinnamon, and salt. Add the cubed bread and gently mix together, using hands or a rubber spatula until the egg mixture is absorbed. Transfer to the prepared pan, and distribute evenly, pressing gently to level the top. Bake for 45 minutes, or until firm and crusty on top.

Let rest at least 15 minutes before serving. Cut into squares or just eat it right out of the pan with a big spoon. Serve with whipped cream or ice cream.
