Preheat oven to 350F.
Cube bread into half-inch cubes and place in a large mixing bowl.
Add into a blender all the remaining ingredients (not the bread).
Blend on high until smooth, approximately one minute.
Using a rubber spatula or blender spatula, transfer blender contents to mixing bowl with bread cubes. Stir to evenly coat bread cubes.
Transfer mixture to a greased 9x13 casserole dish.
Bake 35-45 minutes according to preference or until beginning to turn golden on top.
Top with powdered sugar, strawberries, or maple syrup as desired.
