Baked Cinnamon Roll Casserole
This is what happens when you turn canned cinnamon rolls into a genuine crowd-feeding breakfast bake — cut into pieces, soaked in a cinnamon custard, and baked until golden. It's the recipe I turn to on holiday mornings when there are more people to feed than there's patience to roll and cut individual cinnamon rolls.
The custard soak is what elevates this past just "baked cinnamon rolls" — it gives the whole dish a bread-pudding-like richness that regular cinnamon rolls don't have on their own.

Why This Recipe Works
Cutting the cinnamon rolls into quarters before baking exposes more surface area to the egg custard, so it soaks in more evenly than it would with whole rolls, similar to how bread pudding works. Pressing the pieces down gently after pouring the custard ensures every piece gets coated rather than a few dry spots floating on top.
Ingredients
- 3 (12.4 oz) cans refrigerated cinnamon rolls with icing, cut into quarters
- 4 large eggs
- ½ cup whole milk
- ¼ cup (50g) brown sugar
- 1 teaspoon cinnamon
- 1 teaspoon vanilla extract
- ½ cup chopped pecans (optional)

Baked Cinnamon Roll Casserole
- 3 cans cinnamon rolls
- 4 large eggs
- ½ cup whole milk
- ¼ cup (50g) brown sugar
- 1 teaspoon cinnamon
- Grease a 9x13-inch dish. Cut cinnamon rolls into quarters and scatter in the dish, reserving icing.
- Whisk eggs, milk, brown sugar, cinnamon, and vanilla until smooth.
- Pour over the roll pieces, pressing gently to submerge. Scatter pecans on top if using.
- Bake at 350°F (175°C) for 30-35 minutes until golden and set.
- Drizzle with reserved icing while warm and serve.
Step-by-Step
Step 1: Prepare the Pan
Grease a 9x13-inch baking dish. Cut each cinnamon roll into quarters and scatter the pieces evenly across the dish. Set the icing packets aside — you'll use them at the end.
Step 2: Make the Custard
Whisk the eggs, milk, brown sugar, cinnamon, and vanilla together until smooth and fully combined.
Step 3: Pour Over the Rolls
Pour the custard mixture evenly over the cinnamon roll pieces, pressing gently with a spatula so everything gets coated and slightly submerged. Scatter the chopped pecans over the top if using.
Step 4: Bake
Bake at 350°F (175°C) for 30 to 35 minutes, until the top is golden brown and the center is set rather than jiggly.
Step 5: Glaze and Serve
While the casserole is still warm, drizzle the reserved icing packets evenly over the top. Serve immediately.
Pro Tips
- Press the pieces down after pouring the custard: this ensures every piece gets soaked, not just the ones on top.
- Check the center specifically: the edges of the dish typically finish before the middle, so test doneness there.
- Add the icing after baking, not before: baking it in causes it to melt away instead of staying glossy on top.
- Let it rest a few minutes before serving: it holds together better once it's had a moment to set slightly.
Storage & Make-Ahead
Store leftovers covered in the fridge for up to 3 days. Reheat individual portions in the microwave for 20-30 seconds. This casserole can also be fully assembled (without icing) the night before, covered, and refrigerated — bake straight from the fridge in the morning, adding 5 to 8 extra minutes.
Variations & Substitutions
- Apple version: fold in 1 cup diced apple before baking for a fruitier casserole.
- Cream cheese swirl: dollop softened cream cheese between roll pieces before adding the custard.
- Nut-free version: simply omit the pecans.
- Extra glaze: make a simple powdered sugar and milk glaze if you want more icing than the packets provide.
