Irresistible Cinnamon Roll Casserole Recipe for the Perfect Holiday Breakfast

What Ingredients You Will Need

This recipe uses simple, everyday ingredients that deliver big flavor without requiring much effort. Here’s what you’ll need:

• 2 cans of store-bought cinnamon rolls (I recommend Pillsbury for consistent results)
• 4 large eggs (room temperature for better blending)
• 1 cup whole milk (you can substitute almond milk or oat milk if needed)
• 1/4 cup heavy cream (optional, but adds richness)
• 2 teaspoons vanilla extract
• 1 teaspoon ground cinnamon
• Pinch of salt (balances the sweetness)
• 1/4 cup powdered sugar (for the glaze)
• 1-2 tablespoons milk (to thin the glaze)

Most of these ingredients are pantry staples, and the store-bought cinnamon rolls make this recipe a breeze. If you’d rather make your cinnamon rolls from scratch, go for it—but I promise, the shortcut version is just as delicious.

Equipment Needed

• Baking dish: A 9×13-inch dish works perfectly for this recipe.
• Mixing bowls: You’ll need a few bowls to mix the custard and glaze.
• Whisk: For blending the custard smoothly.
• Knife: To cut the cinnamon rolls before baking.
• Spatula: Great for spreading the glaze evenly over the casserole.

If you don’t have a baking dish in this size, a smaller one will work—you’ll just need to adjust the baking time slightly. I’ve even used a disposable aluminum pan for easy cleanup!

Preparation Method

Follow these simple steps to make your own irresistible cinnamon roll casserole:

1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with butter or non-stick spray.
2. Open the cinnamon roll cans and set the icing packets aside for later. Cut each roll into quarters and spread them evenly in the prepared baking dish.
3. In a medium mixing bowl, whisk together the eggs, milk, heavy cream, vanilla extract, ground cinnamon, and a pinch of salt until fully combined.
4. Pour the custard mixture evenly over the cut cinnamon rolls, making sure all pieces are coated. Gently press the rolls down with a spatula so they soak up the liquid.
5. Bake for 35-40 minutes, or until the top is golden brown and the custard is set. If the edges start to brown too quickly, cover the dish loosely with foil.
6. While the casserole is baking, make the glaze. In a small bowl, whisk together the powdered sugar and 1 tablespoon of milk. Add more milk, a little at a time, until the glaze reaches your desired consistency.
7. Remove the casserole from the oven and let it cool for 5 minutes. Drizzle the glaze generously over the top of the casserole.
8. Serve warm and enjoy the holiday magic!

Cooking Tips & Techniques

• Don’t overbake: Keep an eye on the casserole as it bakes. Overbaking can result in dry cinnamon rolls. You want the center to be set but still slightly soft.
• Use room temperature eggs: This helps the custard blend more smoothly and bake evenly.
• Press down gently: When pouring the custard over the rolls, lightly press them down so they absorb the liquid for a moist texture.
• Double the glaze: If your family loves extra sweetness, make a double batch of glaze to drizzle generously over each serving.
• Make ahead: You can assemble the casserole the night before, cover it tightly, and refrigerate. Bake it in the morning for a low-stress breakfast.

Variations & Adaptations

• Gluten-Free: Use gluten-free cinnamon rolls and ensure your other ingredients are gluten-free certified.
• Dairy-Free: Substitute almond milk or coconut milk for regular milk, and use a dairy-free powdered sugar for the glaze.
• Add fruit: Sprinkle chopped apples or dried cranberries over the cinnamon rolls before pouring the custard for a fruity twist.
• Seasonal twist: Add a pinch of nutmeg or ginger to the custard for extra holiday spice.

I’ve tried adding pecans on top before baking, and they add such a lovely crunch to the casserole. You can also play around with different flavors in the glaze—try adding orange zest for a citrusy surprise!

Serving & Storage Suggestions

This casserole is best served warm, fresh out of the oven. Pair it with a hot cup of coffee or cocoa for the ultimate holiday morning treat!

• Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
• Freezing: Wrap individual portions in plastic wrap and freeze for up to one month. Thaw overnight in the fridge before reheating.
• Reheating: Warm leftovers in the oven at 300°F (150°C) for 10-15 minutes, or microwave for 30-45 seconds.

Fun fact: the flavors of the cinnamon roll casserole deepen after a day in the fridge, making it even more delicious the next day!
