A forgiving, sweet, and cozy cinnamon roll casserole that can be prepped ahead and baked for a perfect breakfast or brunch. Gooey cinnamon-laced layers soaked in custard with a tender center and crisp top.
Use room temperature eggs and milk for a smooth custard. Whisk custard well to avoid egginess. Cover casserole tightly when refrigerating to prevent drying. Watch baking time closely to avoid overbaking. Use included icing for best flavor. Tent with foil if top browns too fast. For dairy-free, use almond milk and coconut oil; for vegan, use vegan cinnamon rolls and flaxseed egg substitute. Gluten-free cinnamon rolls can be used but texture may vary.
