Step 1

Cut bread into cubes or tear into small pieces. Place in a greased 9 x 13-inch baking pan. In a medium bowl, whisk together eggs, milk, half and half, sugar, vanilla, and cinnamon. Pour over bread in the pan.

Step 2

Cover and refrigerate for 2 hours or overnight.

Step 3

Preheat oven to 350 degrees.

Step 4

In a small bowl combine brown sugar, flour and cinnamon. Cut butter into small pieces and add to flour mixture. With a fork blend butter into mixture until it resembles small crumbs; sprinkle over bread in the pan.

Step 5

Cover with foil and bake for 20 minutes. Uncover and bake for another 20-25 minutes or until golden brown and cooked through. To check, shake the casserole. If it wiggles a lot it's not done. Continue to bake until it cooked through completely.
