This cinnamon roll casserole is a go to when you want something easy but indulgent for a weekend brunch. The cinnamon rolls bake up soft and fluffy in a sweet custard and the warm icing drizzled on top just takes it over the top. I started serving this on Christmas mornings and now it is everyone’s most requested holiday breakfast.
My family always gathers around the kitchen as this bakes because the cinnamon smells fill the house. It is so easy that even my teenagers ask to help slice the rolls and pour the custard.
Ingredients
- Canned cinnamon rolls: This shortcut keeps things simple and guarantees gooey texture every time Look for ones with a good amount of cinnamon filling and save the included icing for the finishing touch
- Large eggs: They are essential for a creamy custard and help set everything so the casserole is sliceable Choose the freshest eggs for best texture
- Whole milk and heavy cream: These add extra richness and help soak the bread base Whole milk keeps things light but do not skip the splash of cream
- Granulated sugar: Gives the custard the right amount of sweetness without overpowering the cinnamon
- Pure vanilla extract: Adds warmth and aromatic flavor Always use real vanilla when possible
- Ground cinnamon: Deepens the spice and ties in the classic roll flavor Make sure your cinnamon is fresh for best taste
- Salt: Brings all the flavors into balance and keeps things from tasting overly sweet
- Unsalted butter: Adds a finishing richness on top
- Maple syrup: Sweetens the crust and gives a glossy bakery finish Use real pure maple syrup for the best result
- Reserved icing: The included icing puts this over the top with gooey sweetness Wait to drizzle until right before serving
Step-by-Step Instructions
- Preheat the Oven:
- Heat your oven to three hundred fifty degrees Fahrenheit and butter a nine by thirteen inch baking dish or use a spritz of nonstick spray to make clean up easy
- Prepare the Cinnamon Rolls:
- Cut each cinnamon roll into four pieces Choose a sharp knife and wipe between cuts to keep the spirals neat Scatter the pieces evenly in the baking dish so you get lots of fluffy layers throughout
- Make the Custard:
- In a mixing bowl whisk together eggs whole milk heavy cream sugar vanilla extract cinnamon and salt Give it a solid whisk so there are no streaks This ensures the custard bakes up creamy and even
- Assemble and Soak:
- Pour the custard over the cinnamon rolls pushing gently with a spoon or spatula to make sure every piece gets coated This helps the rolls soak up all the flavor and keeps the bake moist
- Add the Toppings:
- Drizzle melted butter all across the top then slowly pour maple syrup letting it nestle into crevices The syrup and butter meld together for a caramelized sweet crust
- Bake the Casserole:
- Slide the pan into the oven and bake for thirty to thirty five minutes Until the top is golden and set but still a little soft in the center Insert a knife to check if it comes out mostly clean
- Ice and Serve:
- Let it cool for a few minutes This helps the icing melt nicely and not run off Drizzle the reserved icing in a zigzag or swirl as thick or thin as you like Cut into generous squares and serve warm

Every time I bake this the vanilla and cinnamon fill the whole house and take me back to childhood weekends One of my favorite touches is real maple syrup because the flavor is so buttery and rich my little ones call it sticky magic
Storage Tips
Store leftovers tightly covered in the refrigerator for up to four days A quick zap in the microwave or a short warm up in a low oven brings back the soft pillowy texture
