This Cinnamon Roll Casserole is a warm, gooey delight that combines the best of sweet rolls and a cozy breakfast bake. It’s super easy to make with just a few ingredients!
Trust me, waking up to this is like winning the breakfast lottery! I love serving it with a drizzle of icing on top—it makes every bite feel like a special treat. 😋
Key Ingredients & Substitutions
Cinnamon Rolls: Using refrigerated cinnamon rolls is key for convenience. If you want to make it from scratch, a homemade dough with sweet cinnamon filling works well, too. Just make sure it’s rolled up tight!
Eggs: The eggs provide structure and richness. For a vegan option, you can try using flax eggs (1 tablespoon ground flaxseed + 2.5 tablespoons water per egg) to bind the casserole together.
Milk: Whole milk makes this casserole creamy. If you want a lighter version, use skim milk or a plant-based milk like almond or oat milk. I find that oat milk has a nice creaminess without overpowering the flavor.
Vanilla Extract: This adds a lovely depth of flavor. If you run out, a splash of almond extract gives a unique twist. Just use a little less since it’s stronger!
How Do I Ensure My Casserole Cooks Evenly?
To achieve a perfectly baked casserole, pay attention to the mixing and baking steps. Here are some tips:
- Make sure each piece of cinnamon roll is coated in the egg mixture—this prevents dry areas.
- Bake it uncovered to let the top get golden brown.
- Check doneness by inserting a knife or toothpick in the center; it should come out clean if fully set.
- Let it cool a few minutes before serving. This helps it hold together better!
Enjoy this melt-in-your-mouth treat that feels like a warm hug on a plate!

How to Make Cinnamon Roll Casserole
Ingredients You’ll Need:
- 2 (10-count) cans of refrigerated cinnamon rolls with icing
- 4 large eggs
- 1 cup whole milk
- 1 teaspoon vanilla extract
- Optional: powdered sugar or extra icing for drizzling
How Much Time Will You Need?
This Cinnamon Roll Casserole takes about 10 minutes to prep and 30-35 minutes to bake, so you’ll need roughly 45 minutes total. It’s a quick and easy breakfast that’s sure to impress!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This will ensure your casserole bakes evenly and comes out perfectly fluffy. Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Prepare the Cinnamon Rolls:
Open the cans of cinnamon rolls and cut each roll into quarters. This will help all the pieces soak up the egg mixture and bake evenly. Arrange the cut pieces evenly in your prepared baking dish.
3. Mix the Egg Mixture:
In a medium bowl, whisk together the eggs, milk, and vanilla extract until everything is well combined. This mixture will make your casserole rich and custardy!
4. Combine with the Cinnamon Rolls:
Pour the egg mixture evenly over the cinnamon roll pieces, making sure every piece is moistened. This step is important for getting that delicious, gooey texture all throughout the casserole.
5. Bake the Casserole:
Place the baking dish in your preheated oven and bake for about 30-35 minutes. You’ll know it’s done when the casserole is puffed up, golden, and set in the center. Keep an eye on it to avoid over-baking!
6. Cool and Drizzle:
Once done, remove the casserole from the oven and let it cool for a few minutes. This gives it time to set up a bit more. Then, drizzle the included icing over the warm casserole or dust some powdered sugar on top for an extra sweet touch.
7. Serve and Enjoy:
Serve the casserole warm for a deliciously gooey and sweet breakfast treat. It’s perfect for any brunch or family gathering!
With its soft, custardy inside and cinnamon-sweet spirals throughout, this Cinnamon Roll Casserole is the perfect cozy brunch or breakfast dish that everyone will love!
Can I Use Other Types of Cinnamon Rolls?
Absolutely! Feel free to use any brand of refrigerated cinnamon rolls or even other flavors, like caramel or apple cinnamon. Just check that they come with icing or have a similar gooey filling!
Can I Make This Casserole Ahead of Time?
Yes! You can assemble the casserole the night before and cover it tightly with plastic wrap. In the morning, just bake it straight from the fridge, but you may need to add a few extra minutes to the baking time.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat portions in the microwave or in the oven at a low temperature until warmed through. It’s still delicious the next day!
What Can I Serve With This Dish?
This casserole is delightful on its own, but you can serve it with fresh fruit, whipped cream, or extra maple syrup on the side for an added touch of sweetness!
