Overnight Cinnamon Roll Casserole
Make this easy overnight cinnamon roll breakfast casserole using frozen cinnamon rolls in a simple custard base. Drizzle the icing over the top just before serving for a crowd-pleasing dish that will make any brunch more festive during the holidays.
Ingredients
- 2 whole eggs
- 3 additional egg yolks
- 2 cups milk
- 2 tablespoons sugar
- 1 teaspoon cinnamon
- 1 teaspoon vanilla extract
- 1/4 teaspoon kosher salt
- 1 (16 oz) package frozen cinnamon rolls icing packet reserved
- 1/2 cup golden raisins optional, see notes for substitution ideas
- 2 tablespoons butter diced
Instructions
Overnight Prep (Or at least 1 hour before baking):
- Lightly spray a 9x13-inch baking dish with cooking spray and set aside.
- Open the cinnamon rolls package and reserve the packet of icing in the fridge for garnishing tomorrow morning. Break apart the cinnamon rolls and chop them into 4 - 6 pieces each. Sprinkle the cinnamon roll chunks evenly in the baking dish. Sprinkle the golden raisins evenly among the cinnamon rolls if you are using them.
- In a medium-size mixing bowl, whisk together the eggs, egg yolks, milk, sugar, cinnamon, vanilla, and salt.
- Pour the egg mixture over the top of the prepared cinnamon rolls and gently press them to submerge into the liquid. Scatter the cubes of butter evenly over the top of the dish. Cover the baking dish with plastic wrap and chill overnight. This allows the cinnamon rolls to absorb the custard before baking. If you don't have time for an overnight prep, just allow the dish to stand for one hour before baking.
Baking Instructions:
- Preheat the oven to 325°F. Remove the plastic wrap and bake the cinnamon roll casserole for 55 minutes or until the custard is set and the top is golden brown.
- Drizzle the reserved icing over the top of the casserole just before serving. If you want a pretty icing pattern on top, you should let the dish rest for 5 - 10 minutes before decorating. If you spread the icing immediately, it will melt into the cinnamon rolls but will still taste delicious!
Recipe Notes
Note on Golden Raisins:
I think the golden raisins add a lovely flavor and texture to the breakfast casserole but I know not everyone loves them. Some delicious alternative substitutions include:- Dried Craisins
- Currants
- Mini Chocolate Chips
- Chopped Pecans
- Diced Dried Cherries
- Dried Blueberries
- Regular Raisins
- Chopped Candied Orange
