A cozy and easy cinnamon roll French toast casserole perfect for Christmas morning, combining gooey cinnamon rolls with a rich custard soak and a sweet glaze.
For best texture, soak the cinnamon rolls in custard overnight or at least 2 hours. Tent with foil if edges brown too fast. Use fresh ground cinnamon for best flavor. Glaze consistency should be smooth but not too runny. Can be adapted for gluten-free or vegan diets with substitutions.
