Cinnamon Roll Bread Pudding is a delicious way to use leftover bread

About the recipe
Similar to a French toast casserole, bread pudding is a fantastic way to use up odds and ends of bread, making it an economical dish. On the rare occasion that we had leftover cinnamon rolls at the bakery, they made their way into this Saturday special.
Whether you use cinnamon rolls, brioche or another type of sweet bread, this will surely be a crowd-pleaser.

Pour bread mixture into prepared pan, cover tightly in plastic wrap, and refrigerate overnight, or at least 8 hours.
