Overnight Cinnamon Roll Casserole

Jump to Recipe

Warm from the oven and covered in cream cheese frosting, this Overnight Cinnamon Roll Casserole is the kind of breakfast that makes getting out of bed a little easier. It has everything I want in a cozy morning treat—soft cinnamon rolls, a rich vanilla-cinnamon custard, and plenty of sweet icing on top.

And the best part is that you can put it together the night before.

I love recipes like this when I’m planning breakfast for a holiday morning or having people over for brunch. Instead of measuring flour, waiting for dough to rise, and shaping individual cinnamon rolls first thing in the morning, you start with packaged cinnamon rolls and turn them into something a little more special. Cut them into pieces, pour over the creamy egg mixture, and let the refrigerator do the rest of the work overnight.

In the morning, just bake the casserole until the cinnamon rolls are cooked through but still wonderfully soft in the center. After a short rest, pour that cream cheese frosting all over the top. Served warm with coffee and fresh fruit on the side, it’s an easy breakfast I’d happily linger over.

Why You’ll Love This Recipe

There’s a lot to love about this cinnamon roll casserole, but the make-ahead preparation is what really makes it a keeper.

You can prep it the night before. Assemble everything before bed, cover the baking dish, and refrigerate it overnight. The next morning, breakfast is already waiting to go into the oven.

It starts with packaged cinnamon rolls. There’s no yeast dough to mix, knead, shape, or wait on. Refrigerated cinnamon rolls work, and frozen cinnamon rolls are an option too.

The center stays soft and rich. Eggs, heavy cream, vanilla, cinnamon, sugar, and nutmeg create a simple custard that surrounds the pieces of cinnamon roll as they bake.

There’s cream cheese frosting on top. Once the casserole has rested for 10 minutes, the frosting goes right over the warm rolls. It softens over the top and finds its way into the spaces between the pieces.

It feeds a table. With 8 servings in one 9×13-inch baking dish, this is just the sort of breakfast I’d make when family or friends are coming over.

Overnight Cinnamon Roll Casserole Ingredients

Here’s a quick breakdown of what each ingredient brings to this cinnamon roll casserole:

Butter – melted butter coats the bottom of the baking dish, adding richness and helping keep the cinnamon rolls from sticking.
Cinnamon Rolls – these are the shortcut that makes this recipe so easy. You can use a package of frozen cinnamon rolls or refrigerated cinnamon rolls. Cutting them into quarters creates plenty of little pieces for the creamy mixture to surround as they bake.
Eggs – the base of the custard. They help the cream mixture set around the cinnamon rolls and give the casserole its soft, French toast-like texture.
Heavy Whipping Cream – makes the custard extra rich and creamy and helps keep the center of the casserole soft.
Granulated Sugar – adds a little extra sweetness to the custard that soaks into the cinnamon roll pieces.
Vanilla Extract – adds warm vanilla flavor and works especially well with the cinnamon and cream cheese frosting.
Cinnamon – even though there’s already cinnamon in the rolls, a little more in the custard gives the whole casserole that cozy cinnamon flavor.
Nutmeg – you only need a small amount. It adds a warm, gently spiced note that complements the cinnamon and vanilla.
Cream Cheese Frosting – use the frosting that comes with the cinnamon rolls. Pour it over the casserole after it has rested for 10 minutes for that sweet, creamy finish.

Remove from oven and let cool 10 minutes.
Pour icing from cinnamon roll package over casserole, serve, and enjoy!

Expert Tips

This recipe is wonderfully simple, but a few little details will help you get that soft, cinnamon-filled casserole you’re looking for.

Keep the cinnamon roll pieces about the same size. Cutting each roll into quarters gives you pieces that can bake more evenly and makes it easier to spread them throughout the dish.

Don’t skip the butter on the bottom. Swirl the melted butter across the entire base of the baking dish before arranging the cinnamon rolls.

Make it ahead when you can. The overnight option is especially convenient when you want breakfast ready with minimal work the next morning. Assemble the casserole, cover it with foil, and tuck it into the refrigerator until morning.

Pay attention to the center as it bakes. You want the rolls cooked through, but you don’t want to lose that lovely soft center. Start checking around the 30-minute mark.

Give it the full 10-minute rest. I know it’s tempting to add the frosting immediately, but let the casserole cool for the specified 10 minutes first. Then pour the icing over the top and serve.

Recipe Variations

I’d make the original recipe exactly as written the first time. After that, there are plenty of ways to change what you serve with or on top of it without altering the base recipe.

For a little crunch, scatter toasted pecans or walnuts over each serving. They’re especially good against the soft cinnamon rolls and creamy frosting.

If you want something fresh to balance the sweetness, add strawberries, raspberries, blueberries, or sliced bananas at the table.

For cozy fall breakfasts, I love the idea of spooning warm cooked apples over individual portions. Cinnamon rolls and apples are such a natural pairing.

You could also keep things incredibly simple and finish each serving with just a tiny dusting of cinnamon over the cream cheese frosting.

Storage & Reheating

This casserole is especially good when it’s freshly baked and still warm, but leftovers make a pretty wonderful breakfast too.

Once the leftovers have cooled, cover them well or transfer them to an airtight container and refrigerate promptly. They can be kept in the refrigerator for 3 to 4 days.

For a quick breakfast, reheat an individual portion in the microwave until warmed through. If you’re reheating several servings, place them in an oven-safe dish, cover, and warm them in the oven until heated through.

Try not to overheat the casserole. Warming it just until hot helps preserve the soft texture of the cinnamon roll pieces.

Serving Suggestions

For me, this is a coffee-and-slow-morning kind of breakfast. Serve the casserole warm, while the cinnamon rolls are soft and the cream cheese frosting is still settling into the top.

Because the casserole itself is sweet and rich, fresh fruit makes an especially nice partner. Try a bowl of berries, sliced oranges, bananas, or a simple mixed fruit salad.

If you’re putting together a larger brunch, add something savory alongside it. Scrambled eggs, breakfast potatoes, or another savory egg dish can turn a piece of cinnamon roll casserole into a more complete meal.

And, of course, pour something good to drink. Hot coffee, tea, or cold milk all work beautifully with cinnamon, vanilla, and cream cheese frosting.

It’s an especially lovely recipe for Christmas morning, weekend brunch, overnight guests, or any morning when you want breakfast to feel special without spending the whole morning making it.

Recipe FAQs

1. Can I prepare this cinnamon roll casserole the night before?

Yes, you can definitely make it ahead. Simply assemble the casserole, cover the baking dish with foil, and refrigerate until you’re ready to bake, up to overnight. Then bake at 375°F for 30–35 minutes.

2. Do I have to let the casserole sit overnight?

No, an overnight rest is not required. You can prepare and bake the casserole the same day. Chilling it overnight is simply a great option when you want to get breakfast prep out of the way ahead of time.

3. Can I use refrigerated cinnamon rolls instead of frozen?

Yes! You can use 1 package frozen cinnamon rolls (12 rolls) or 2 cans refrigerated cinnamon rolls. Just cut the cinnamon rolls into quarters before arranging them in the baking dish.

4. How do I know when cinnamon roll casserole is done?

The cinnamon rolls should be cooked through but still soft in the center. Start checking around 30 minutes. If the center still looks doughy or undercooked, give it a little more time. The total baking time should be about 30–35 minutes.

5. When should I put the icing on the cinnamon roll casserole?

Wait until after baking. Let the casserole cool for 10 minutes, then pour the cream cheese frosting from the cinnamon roll package over the top. The casserole will still be warm enough to soften the frosting without adding it straight out of the oven.
