1 loaf cinnamon raisin bread
8 large eggs
3 cups whole milk
1 cup half and half
1 tsp. ground cinnamon
1 tsp. vanilla
Walnut Streusel Topping:
1/3 cup brown sugar
1/3 cup flour
1/3 cup butter, cut into chunks
1 cup chopped walnuts
Preparation:
Grease a 9 x 13 baking dish (compare prices).
Cut cinnamon bread into 1-inch chunks. Place in the baking dish, making two layers.
Whisk together eggs, milk, half and half, cinnamon and vanilla. Pour over bread, pressing to coat the bread well. Cover with foil, and refrigerate overnight.
Remove the casserole from refrigerator. Preheat the oven to 350 degrees F.
In a small bowl, mix brown sugar and flour together. Cut in the butter with a pastry blender (compare prices) or two knives. Stir in chopped walnuts. Scatter the topping over the casserole.
Bake 45 minutes to 1 hour. If you prefer a softer, more custard-like French toast, bake the casserole for 45 minutes. If you like a crunchier, more toasted texture, bake it for 1 hour.
