Easy Cinnamon Roll Christmas Morning Casserole Recipe

By the third year I made this casserole, I stopped pretending it was a new tradition and just accepted it. Three years in a row, same pan, same sticky fingers from tearing open those cans of cinnamon rolls, same quiet kitchen at 6 AM while the rest of the house still slept. The first time, I was desperate—I had overslept, the kids were already awake, and I needed something that felt special without requiring me to actually bake anything from scratch. The second time, I told myself it was just convenient. The third time, I realized I was looking forward to it.

This isn’t a recipe that tries to be fancy. It is a recipe that understands Christmas morning—the chaos of wrapping paper, the coffee that goes cold, the one relative who always asks what’s for breakfast before anyone has even sat down. This casserole handles all of that. It goes into the oven while everyone is still in pajamas, and it comes out smelling like butter and cinnamon and brown sugar, which is basically the official scent of December 25th.

Honestly? I have tried the homemade dough version. I have attempted the from-scratch cream cheese frosting. And you know what? It was fine. But this version—the one that starts with refrigerated cinnamon rolls—this is the one that actually gets made year after year. Because Christmas morning does not need a project. It needs something warm, something sweet, and something that lets you sit down with your coffee while the oven does the work. This casserole is that thing.

Why You’ll Love This Recipe

• Minimal Effort, Maximum Impact : This comes together in about 15 minutes of active prep. The oven handles the rest. You can be sipping eggnog in your slippers while it bakes.
• Pantry-Friendly Ingredients : Cinnamon rolls, eggs, heavy cream, butter, brown sugar. That is it. No special trips to the store for obscure extracts or fancy baking chocolate.
• Perfect for Christmas Morning Chaos : This is the breakfast that keeps on giving. It feeds a crowd, it reheats beautifully, and it doesn’t require anyone to stand at the stove flipping pancakes while missing the gift opening.
• Crowd-Pleaser Across All Ages : Kids devour it. Adults go back for seconds. That one picky uncle who “doesn’t do breakfast casseroles” will quietly ask for the recipe.
• Unbelievably Cozy : The texture is what gets me every time. The cinnamon rolls stay soft and pillowy in the middle, while the edges get slightly caramelized and chewy. The cream cheese frosting melts into every crevice. It is comfort food in casserole form.

I have tested this recipe with different pans, different oven temperatures, and different resting times. I have burned the bottom of one batch (do not skip the butter, trust me) and undercooked another because I was impatient. This version is the Goldilocks of cinnamon roll casseroles—just right, every time.

What Ingredients You Will Need

This recipe uses simple, everyday ingredients to create something that feels far more indulgent than the sum of its parts. Most of these are probably already in your kitchen, which is half the magic of this dish.

• Cinnamon rolls (2 cans, 12.4 oz each) – Use the big, fluffy, iced cinnamon rolls from the refrigerated section. I prefer Pillsbury Grands! for their size and texture, but store brands work fine too. The key is getting the ones with the cream cheese frosting packet included—do not accidentally grab the ones without icing.
• Eggs (4 large) – Room temperature if you remember, straight from the fridge if you don’t. They help bind the casserole and give it that custard-like richness between the cinnamon roll layers.
• Heavy cream (1/2 cup) – This adds the decadence. You can substitute half-and-half in a pinch, but the casserole will be slightly less creamy. Do not use milk unless you are truly desperate—the texture changes noticeably.
• Unsalted butter (1/4 cup, melted) – Brushed on the bottom of the pan to prevent sticking and add richness. I have forgotten this step exactly once, and spent 20 minutes scrubbing caramelized sugar off my baking dish. Learn from my mistake.
• Light brown sugar (1/4 cup, packed) – Sprinkled between layers for extra caramelization. Dark brown sugar works too if you want a deeper molasses flavor.
• Ground cinnamon (1 teaspoon) – Because you can never have too much cinnamon in a cinnamon roll casserole. I use Saigon cinnamon for its warmth, but any variety works.
• Vanilla extract (1 teaspoon) – Enhances the sweetness and rounds out the flavor profile. Pure vanilla is best, but imitation works perfectly fine here.
• Cream cheese frosting (from the cinnamon roll cans) – This is your secret weapon. Reserve it from the cans and drizzle it over the hot casserole right when it comes out of the oven.

Optional additions: Chopped pecans or walnuts for crunch, raisins if you are one of those people (no judgment), or a pinch of nutmeg for extra warmth.

Equipment Needed

• 9×13 inch baking dish – Glass or ceramic works best for even heat distribution. Metal pans can cause the edges to brown too quickly.
• Large mixing bowl – For whisking the egg mixture.
• Whisk – A fork works in a pinch, but a whisk gives you a smoother custard base.
• Sharp knife or kitchen shears – For cutting the cinnamon rolls into quarters. Kitchen shears are actually easier—less messy and more precise.
• Small saucepan or microwave-safe bowl – For melting the butter.
• Pastry brush (optional) – For brushing the butter evenly across the pan. A paper towel works too.
• Spatula – For spreading the cinnamon roll pieces evenly.

That is genuinely it. No stand mixer, no food processor, no specialty pans. This recipe was designed for normal kitchens with normal equipment.

Preparation Method

1. Preheat your oven to 350°F (175°C). Position the rack in the center of the oven. While it heats, generously butter your 9×13 baking dish with the melted butter. Make sure you get the corners—caramelized sugar loves to hide there and burn.
2. Open both cans of cinnamon rolls. Set the frosting packets aside. You will need them later. Do not, under any circumstances, eat one of the cinnamon rolls raw. I know they are tempting. I have done it. It ruins the symmetry of the casserole.
3. Cut each cinnamon roll into quarters. Use a sharp knife or kitchen shears. The pieces do not need to be perfect—roughly equal sizes are fine. You want them bite-sized so the custard can soak into every crevice.
4. Arrange half of the cinnamon roll pieces in the prepared baking dish. Spread them into an even layer. They should be touching but not crammed together. Sprinkle half of the brown sugar and half of the cinnamon over this layer.
5. Add the remaining cinnamon roll pieces on top. Again, spread them evenly. Sprinkle the remaining brown sugar and cinnamon over the top layer. Press down gently with your spatula so everything settles.
6. In your mixing bowl, whisk together the eggs, heavy cream, and vanilla extract. Whisk until the mixture is smooth and slightly frothy, about 30 seconds. Do not over-whisk—you are not making scrambled eggs here.
7. Pour the egg mixture evenly over the cinnamon roll pieces. Take your time with this step. Pour slowly, letting the custard seep into all the nooks and crannies. Use your spatula to gently press down any pieces that are sticking up above the liquid.
8. Let the casserole rest for 10-15 minutes. This is not optional. The resting time allows the cinnamon rolls to absorb the custard, which prevents dry spots. Use this time to clean up your workspace or pour yourself a mimosa.
9. Bake for 28-32 minutes. The casserole is done when the top is golden brown and the center is set but still slightly jiggly. A knife inserted into the center should come out clean, though there may be some butter pooling around the edges—that is normal.
10. Remove from the oven and let cool for 5 minutes. This is the hardest part. The kitchen will smell like a bakery exploded in the best possible way. Resist the urge to dig in immediately.
11. Drizzle the reserved cream cheese frosting over the top. Warm the frosting packets slightly in a bowl of hot water for 10 seconds if they are too thick to drizzle. Use a spoon or a piping bag—whatever you have. Spread it gently with a spatula if you prefer an even coating.
12. Serve warm. Scoop out portions with a large spoon or spatula. The casserole will be soft and pillowy, with caramelized edges and gooey frosting in every bite.

Cooking Tips & Techniques

I have made this casserole at least a dozen times, and I have made every mistake in the book so you do not have to. Here is what I learned:

• Do not overbake. The casserole will continue to cook slightly as it rests. If you wait until the center is completely firm, the edges will be dry. Pull it out when the center still has a slight wobble.
• Let it rest before serving. Five minutes minimum. Ten is better. This allows the custard to set fully so your casserole holds its shape instead of turning into sweet soup.
• Use room temperature eggs. Cold eggs can shock the custard mixture and create uneven cooking. If you forgot to take them out ahead of time, place them in a bowl of warm water for 5 minutes.
• Do not skip the brown sugar layer. The cinnamon rolls are already sweet, but the brown sugar creates that caramelized crust on the bottom and edges that makes this dish special. It is not optional.
• Grease the pan generously. I cannot stress this enough. The sugar in the cinnamon rolls will caramelize and stick to an ungreased pan. Use butter, not cooking spray—the flavor is better.
• Cut the cinnamon rolls evenly. This is one place where precision matters. Uneven pieces will cook at different rates, leaving you with some underdone and some overdone sections.

One time I forgot the heavy cream entirely and just used milk. The casserole came out watery and the texture was off. Another time I used too much egg and it turned into a cinnamon-flavored quiche. Both were edible but not memorable. Stick to the ratios in this recipe and you will nail it.

Variations & Adaptations

• Make it ahead. Assemble the casserole the night before, cover it tightly with foil, and refrigerate. In the morning, let it sit on the counter for 20 minutes while the oven preheats, then bake as directed. You may need to add 5 minutes to the baking time.
• Add fruit. Layer in 1/2 cup of fresh or frozen blueberries, raspberries, or chopped apples between the cinnamon roll layers. The tartness cuts through the sweetness beautifully.
• Nutty version. Sprinkle 1/2 cup of chopped pecans or walnuts over the top before baking. Toast them first for extra flavor.
• Gluten-free option. Use gluten-free cinnamon rolls. The texture will be slightly different, but the casserole format actually works well with gluten-free dough because the custard keeps everything moist.
• Dairy-free adaptation. Substitute the heavy cream with full-fat coconut cream and use a dairy-free butter alternative. The flavor will shift slightly, but the texture holds up surprisingly well.
• Spiced variation. Add 1/4 teaspoon of nutmeg, cardamom, or pumpkin pie spice to the egg mixture for a more complex flavor profile.
• Chocolate cinnamon roll casserole. Use chocolate-filled cinnamon rolls instead of the regular ones. The combination is dangerously good.

I have tried the apple version twice—once with fresh Granny Smith apples and once with canned apple pie filling. The fresh apples were better because they held their texture and provided a tart contrast. The canned version was sweeter and mushier, which some people might prefer. Experiment and find your favorite.

Serving & Storage Suggestions

Serve this casserole warm, straight from the oven. It pairs beautifully with a side of crispy bacon or breakfast sausage to balance the sweetness. A dollop of whipped cream on top is never a bad idea, and a sprinkle of fresh cinnamon adds a nice visual touch.

For beverages, coffee is the obvious choice—the bitterness cuts through the sugar perfectly. A cold glass of milk works for the kids, and mimosas or a festive Christmas punch make it feel like a celebration.

Storage: Leftovers (if you have any) keep well in an airtight container in the refrigerator for up to 3 days. The casserole will soften slightly as it sits, but the flavor actually improves overnight as the cinnamon and sugar meld together.

Reheating: The microwave works in a pinch—30 seconds per portion. But for the best texture, reheat in a 350°F oven for 10 minutes. The edges will crisp back up, and the center will get warm and gooey again. You can also reheat individual portions in an air fryer at 300°F for 3-4 minutes.

Freezing: This casserole freezes surprisingly well. Bake it completely, let it cool, wrap it tightly in plastic wrap and then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat in a 350°F oven for 15-20 minutes. Do not add the frosting until after reheating.

Nutritional Information & Benefits

Let’s be real—this is not a health food. It is a Christmas morning indulgence, and that is okay. That said, here is the estimated nutritional breakdown per serving (based on 12 servings):

• Calories: 380
• Total Fat: 18g
• Saturated Fat: 9g
• Cholesterol: 95mg
• Sodium: 520mg
• Total Carbohydrates: 48g
• Dietary Fiber: 1g
• Sugars: 28g
• Protein: 7g

The eggs and heavy cream provide protein and calcium, while the cinnamon has anti-inflammatory properties and can help regulate blood sugar. The brown sugar and frosting… well, they provide happiness, which is arguably the most important nutrient on Christmas morning.

If you are watching your sugar intake, you can reduce the brown sugar by half or skip the drizzle of extra frosting. The casserole will still be plenty sweet from the cinnamon rolls themselves.

Conclusion

This cinnamon roll Christmas morning casserole is the breakfast you did not know you needed until you tried it. It is easy enough for a harried parent, special enough for a holiday gathering, and delicious enough to become a family tradition. The fact that it starts with canned cinnamon rolls is not a compromise—it is a strategy. Christmas morning is chaotic enough without adding from-scratch pastry to the mix.

I love this recipe because it lets me be present. I am not stuck in the kitchen whisking dough or monitoring a complicated sauce. I am in the living room, watching the kids tear into presents, drinking coffee that is actually still hot, and knowing that in 30 minutes, something incredible will emerge from the oven.

Frequently Asked Questions

Can I use homemade cinnamon rolls instead of canned?

Yes, absolutely. If you have a favorite homemade cinnamon roll recipe, you can use it here. Just make sure the rolls are fully baked before assembling the casserole, since the custard mixture will not cook raw dough evenly. The texture will be slightly different—homemade rolls tend to be less fluffy than the canned version—but the flavor will be fantastic.

Can I make this casserole dairy-free?

Yes, with a few substitutions. Use full-fat coconut cream instead of heavy cream, a dairy-free butter alternative for greasing the pan, and check the label on your cinnamon rolls—some brands contain dairy. The cream cheese frosting is harder to replace, but you can make a simple glaze with powdered sugar and dairy-free milk instead.

How do I prevent the bottom from burning?

This usually happens when the pan is not greased enough or the oven temperature is too high. Make sure you coat the entire bottom and sides of the pan with butter. If your oven runs hot, reduce the temperature to 325°F and bake for a few extra minutes. Glass and ceramic pans also distribute heat more evenly than metal, which helps prevent hot spots.

Can I add extra cream cheese frosting?

Absolutely. If you want a thicker layer of frosting, you can make a quick cream cheese glaze by mixing 4 ounces of softened cream cheese with 1 cup of powdered sugar and 2 tablespoons of milk. Drizzle it over the casserole after the reserved frosting from the cans. Just be aware that this will significantly increase the sweetness level.

How far ahead can I assemble this casserole?

You can assemble it the night before and refrigerate it for up to 12 hours. If you are making it further in advance, freeze the unbaked casserole for up to 1 month. Thaw it overnight in the refrigerator before baking. The texture will be slightly softer than a freshly assembled casserole, but the flavor will still be wonderful.
