Ingredient Notes

Just 6 ingredients are all you need to make this delicious cinnamon roll breakfast bake.

• Cinnamon Rolls: We like Pillsbury cinnamon rolls but you could use the store brand or homemade.
• Eggs: We use Eggland’s Best large eggs.
• Milk: I use whole milk because that is what we always have on hand.
• Vanilla: I use pure vanilla extract, imitation vanilla can be used.
• Ground Cinnamon: We add a little to the egg mixture to make this even more cinnamon-y.
• Sour Cream: This is added to the icing that comes with the cinnamon rolls because, well, why not?! It makes the icing go farther and is totally yummy.

How to Make Our Easy Cinnamon Roll Casserole

1. Preheat oven to 375° and spray a 9″ X 13″ casserole dish with cooking spray.
2. Set icing aside for later and cut cinnamon rolls into fourths and put into an even layer in the prepared baking dish.
3. In a medium bowl whisk together eggs, milk, vanilla and cinnamon. Pour over cinnamon roll pieces and bake for 22 – 25 minutes or until golden brown.
4. When the casserole comes out of the oven microwave the icing in a small bowl for 10 – 15 seconds. Stir in the sour cream and mix until combined. Pour icing over warm casserole and allow icing to set up a couple of minutes before you cut and serve.

To Make Ahead of Time

Our cinnamon roll casserole recipe is perfect for any special occasion or holiday celebrations. It’s also great for Sunday morning or any day of the week.

We also like to make this when we have guests in from out of town. It always gets rave reviews. It’s also good if you have guests but still have to get up and go to work. You can assemble it the night before and stick it in the fridge with a note on how to bake it. This way, your guests can have a warm sweet treat. They just have to stick it in the oven and then frost it when it comes out. 

Just assemble it the night before and cover with plastic wrap or aluminum foil, then bake it the next morning. Store it and the icing in the refrigerator. You may need to increase the cook time by 5 minutes. Watch carefully and take it out when it is a nice golden brown color.

Tips & Tricks

• If using homemade cinnamon rolls you will need about 16, depending on the size of your cinnamon rolls. This is also a very forgiving recipe so as long as they all fit in your casserole dish then you will just have to adjust the bake time, if necessary. You will also need to whip up a batch of icing, I have a yummy maple glaze recipe that would make this delicious breakfast casserole even more delicious.
• Use a sharp knife or even a pizza cutter to make quick work of cutting the cinnamon rolls into bite size pieces.

Substitutions & Additions

• Want to make this more like a French toast casserole? Drizzle with a cup of maple syrup before putting it into the oven.
• Use any milk you like. Soy milk, oat milk, almond milk or even heavy cream can be swapped with the whole milk I use.
• Swap the sour cream with cream cheese to make cream cheese icing. Just be sure the cream cheese is room temperature so it will blend with the icing.
• Add in fresh blueberries, blackberries, raspberries or chopped strawberries or peaches to change this up a bit.
• Add in a cup or so of chopped walnuts or pecans.
