Dishes like this Overnight Cinnamon Roll Casserole are the sort of make-ahead brunch treats that makes life super sweet. Lightly toasted brown and serve rolls are cubed and smothered in a rich sweet cinnamon spiced egg custard then popped into the fridge to chill overnight. After baking until golden, they’re frosted with a rich cream cheese frosting for the cherry on top.
It’s no wonder make-ahead casseroles are so popular. I love them too, as pre-assembling dishes gives me the opportunity to plan and prep in advance. All the same reasons you love them right? Then there’s my love of pretty much anything enhanced with fragrant cinnamon. To me, the smell of anything with cinnamon baking is darn near intoxicating. It just makes me feel warm and fuzzy inside. These overnight cinnamon rolls become pretty and puffed while baking due to the rich egg custard. After resting for a few minutes, they do settle a bit. This is completely normal so, don’t panic when you see it happen. The custard is so rich and just like my Pull Apart Cinnamon Breadsticks, Cinnamon Roll Bread and Cinnamon Roll French Bread this recipe is a regular rotation on our weekend brunch menu.
