Cinnamon Roll Casserole Recipe

This cinnamon roll casserole is as tasty as it gets! It combines fluffy cinnamon rolls with buttery warm spices and a sweet icing that's to die for! Honestly, as far as easy breakfast casserole recipes go, this one is tough to beat. I mean, just 5 minutes of prep work is all it takes to put together, and then the oven does all of the heavy lifting after that. 

Why You'll Love This Cinnamon Roll Casserole Recipe

This cinnamon roll casserole is made by cutting your favorite refrigerated cinnamon rolls into bite-sized pieces and then layering them with a buttery vanilla batter to make them extra ooey-gooey and tender. Then, after it bakes, it's topped off with warm icing and pure maple syrup. Every bite is just as good - if not better - than the last, and if you love cinnamon rolls then you're going to love, love, love this casserole.

Now, with that said, this Pillsbury cinnamon roll casserole isn't just super delicious; it's super easy to make, too. In fact, just a few simple steps are all you'll need to follow to make it. Honestly, all you have to do is break apart the cinnamon rolls, mix the batter, add it on top of the rolls, and then bake everything together to golden brown perfection in a casserole dish. That's actually all there is to it!

By the way, I love serving this cinnamon roll breakfast bake on Christmas morning along with this Christmas breakfast casserole. Everyone in my family goes crazy for the two of them, so I highly recommend making both of these easy casseroles if you're hosting Christmas morning, or you can serve it with one of my other Christmas casserole recipes.

Ingredients Needed

Now, something else I love about this cinnamon roll casserole recipe is that it's made with all kitchen staples. And that means there's a good chance you'll have most - if not all - of them at home already.

Anyway, here's what you need to make this cinnamon roll casserole recipe:

• Can of cinnamon rolls- cut into pieces.
• Melted butter
• Eggs
• Milk- any kind works.
• Vanilla extract
• Cinnamon- optional for more flavor.
• Maple syrup
• Vanilla icing- from the cinnamon roll tubes or homemade icing. I have a small batch sugar cookie recipe on the blog that includes a really simple icing recipe that goes terrific on these cinnamon rolls. A cream cheese icing works great too.

By the way, if you're looking for another tasty breakfast casserole recipe, you can use a lot of these same ingredients to make this Pioneer Woman French toast casserole as well!

If you're not in the mood for a casserole, you can use some of the ingredients to make this coffee cake or cinnamon roll peach cobbler!

How To Make Cinnamon Roll Casserole

Step 1: Cut The Cinnamon Rolls

First things first, you'll want to preheat the oven to 375°F (180°C) and grease a 9-inch baking dish with half of the melted butter.

Next, you'll want to cut-up the refrigerated cinnamon rolls of your choice - I like to use Pillsbury cinnamon rolls - into any-sized pieces that you want. Then, after you've done that, you can add the cinnamon roll pieces to the prepared baking dish.

Step 2: Make the Batter

So, now you can take out a large bowl and add the eggs, milk, vanilla extract, and remaining melted butter to it. Oh, and if you want to give this cinnamon roll casserole even more of a cinnamony flavor, you can also add a touch of cinnamon to the batter as well.

Anyway, once you've added all of those ingredients into the bowl, you can give them mix with a whisk - or fork - until they're fully combined with one another.

Step 3: Build and Bake

Ok, now that the batter is mixed up well, you can pour it evenly on top of the cinnamon rolls in the baking dish. Then, after you've done that, you'll want to drizzle the maple syrup all over the top of the cinnamon rolls and bake the casserole for 25 minutes.

Once the cinnamon roll casserole is baked to perfection, remove it from the oven and let it cool for 5 minutes. While it's cooling, you can make the icing - or cream cheese icing - if you're not using the one from the package.

Finally, serve this cinnamon rolls casserole warm with the icing drizzled all over top, along with a sprinkle of extra cinnamon. Enjoy!

Make Ahead Cinnamon Roll Casserole Instructions

1. Prepare the cinnamon roll casserole as directed above up until it's ready to be put in the oven.
2. Cover the casserole dish with plastic wrap and refrigerate it overnight. 
3. When you're ready to serve, let it sit at room temperature for 30 minutes, then bake as directed above.

Serving Suggestions

Now, when it comes to serving this cinnamon roll casserole, you can really turn your breakfast or brunch into a whole feast. I love pairing this sweet, gooey casserole with a few savory or fresh sides to balance it out.

Here are some serving ideas to make your cinnamon roll casserole breakfast complete:

• Classic Breakfast Sides: Serve alongside scrambled eggs or an egg casserole (to add some protein) and crispy bacon or sausage. The salty, savory flavors of bacon or sausage are chef’s kiss with the sweet cinnamon rolls!
• Fresh Fruit: A side of fresh fruit or a vibrant fruit salad adds a refreshing contrast. The juicy fruit lightens up the rich casserole – plus, fruit makes the table look gorgeous.
• Yogurt or Parfait: Spoon out some creamy Greek yogurt or build simple yogurt parfaits with berries. The tang from yogurt pairs nicely with the sweetness of the casserole (and makes breakfast feel a bit more balanced).
• Potatoes: You can’t go wrong with hash browns or home fries on the side. That crispy potato goodness gives your brunch a hearty, diner-style touch to go with the soft, gooey casserole. I love serving it with these fried potatoes and onions.
• Drinks: Of course, serve this casserole with hot coffee or tea – it's perfect for dunking a bite! A festive holiday mimosa or a mug of hot cocoa would be an indulgent pair for a special occasion.

Feel free to mix and match. This cinnamon roll casserole is a star on its own, but a few sides can take your brunch to the next level. And if you’re making it for a holiday morning (think Christmas or Easter brunch), consider adding a savory egg bake or breakfast sausage casserole to really round things out. Trust me, your family or guests will be beyond impressed with the spread!

How To Store & Reheat Cinnamon Roll Casserole

If you end up with some leftovers, you can either put a lid on the casserole dish or transfer the cinnamon rolls to an airtight container. Stored either of these ways, your leftover cinnamon rolls will last in the fridge for around 2-3 days. Alternatively, if you want to keep your leftovers for even longer, you can store 'em in an airtight container in the freezer for up to 2 months.

Once you're ready to enjoy this delicious cinnamon roll casserole again, you'll definitely want to warm it back up. There's nothing like a warm cinnamon roll, am I right?!

To do that, you can just put your leftovers on a microwave-safe plate and microwave 'em in 10-second increments until warm. However, if you're heating up a few servings of leftovers at once, you'll want to put 'em back in a baking dish and warm them in the oven at 350°F for about 10 minutes - or until they're warm and soft. 

Cinnamon Roll Casserole Recipe FAQS

Can I make this cinnamon roll casserole in a slow cooker/crockpot?

Yes, you can! For a crockpot cinnamon roll casserole, prepare everything as directed (cut the cinnamon rolls, pour the custard and syrup over them) but instead of baking in the oven, assemble it in your slow cooker. Cook on LOW for about 2½ to 3 hours. It will puff up and set into a lovely casserole. Once it’s done, turn off the heat and drizzle the icing on top. The edges might get a little crisp and caramelized, which actually tastes amazing. This slow-cooker method is great for saving oven space during busy holiday mornings. (Pro tip: use a slow cooker liner or spray the crockpot with cooking spray first for easier cleanup.)

How do I make a gluten-free cinnamon roll casserole?

It’s easy to make this recipe gluten-free with one swap – the cinnamon rolls! Use gluten-free cinnamon roll dough instead of the regular kind. There are a few brands that sell gluten-free refrigerated cinnamon rolls (check stores that have a gluten-free refrigerated section or even bake shops). Prepare the recipe exactly the same way. The gluten-free rolls might be a bit smaller or take slightly less time to bake, so start checking doneness a few minutes early. The rest of the ingredients (eggs, milk, etc.) are already gluten-free. After baking and icing, you’ll have a casserole that’s just as ooey-gooey and delicious. In fact, your guests probably won’t even realize it’s gluten-free unless you tell them!

Can I use frozen cinnamon rolls or unbaked homemade rolls?

You can – with a little planning. If you have frozen unbaked cinnamon roll dough, let it thaw just enough so you can cut it into pieces (it should still be cold and firm, not fully risen or squishy). Assemble the casserole as usual with the semi-frozen dough pieces and custard in your baking dish. Then cover it and refrigerate overnight. This overnight rest serves two purposes: it allows the dough to finish thawing and start rising, and it lets the egg mixture soak in. In the morning, take the casserole out of the fridge about 30 minutes before baking (to take the chill off) and then bake as directed. You may need to add an extra 5-10 minutes to the bake time since the dough was starting from cold. The casserole will turn out wonderful – the rolls will have risen beautifully and baked into a soft, tender creation. (If using homemade cinnamon roll dough, the same overnight method works, or you can let the cut dough rise in the dish until puffy and then bake immediately.)
