Cinnamon Roll Casserole

This Cinnamon Roll Casserole is my breakfast take on one of the best comfort foods. It has layers of soft cinnamon roll pieces and creamy vanilla custard with plenty of sweet cinnamon swirls and a generous drizzle of vanilla icing.

My cinnamon roll casserole recipe starts by cutting refrigerated cinnamon rolls into bite-sized pieces and spreading them in a baking dish. The soft cinnamon rolls are then covered with a mixture of eggs and milk until evenly coated for a creamy and delicious breakfast casserole. The other key to this cinnamon roll casserole is the warm cinnamon flavor. Not only does it have cinnamon swirls from the rolls but it also has vanilla and maple syrup with a little extra ground cinnamon. Every component of this cinnamon roll casserole is flavorful on its own which means the whole thing is ridiculously good.

Ingredients

Here is what I use for this recipe :

• Refrigerated cinnamon rolls with icing: Provide the soft cinnamon dough and sweet swirls that form the base of the casserole while the included icing creates the creamy finishing drizzle.
• Large eggs: Bind the cinnamon roll pieces together while creating a soft custard texture that holds the finished casserole in individual portions.
• Whole milk: Combines with the eggs to create a creamy custard that keeps the cinnamon rolls tender during baking.
• Pure maple syrup: Adds rich sweetness and a subtle caramel flavor that complements the cinnamon filling throughout the casserole.
• Vanilla extract: Enhances the sweet bakery flavor and adds warmth to the custard mixture.
• Ground cinnamon: Deepens the cinnamon flavor and creates warm brown speckles throughout the creamy custard.
• Unsalted butter: Coats the baking dish to prevent sticking while adding a buttery flavor around the golden casserole edges.

Tools I Use :

• 9 by 13 inch ceramic baking dish: Holds the cinnamon roll pieces and custard in an even layer while allowing the casserole to bake until golden and fully set.
• Medium mixing bowl: Provides enough space to combine the eggs and milk with the other custard ingredients without spilling.
• Whisk: Blends the eggs and milk into a smooth mixture while distributing the maple syrup and cinnamon.
• Wooden cutting board: Provides a stable area for dividing the refrigerated cinnamon rolls into quarters.
• Sharp kitchen knife: Cuts the cinnamon roll dough into manageable sections while preserving the visible cinnamon layers.
• Measuring cups and spoons: Measure the custard ingredients accurately for a balanced texture and consistent sweetness.
• Oven: Provides consistent heat to puff the cinnamon rolls and set the custard while producing golden edges.
• Serving spatula: Lifts the tender casserole portions from the baking dish while keeping the cinnamon layers mostly intact.

Instructions

Step 1: Cut the cinnamon rolls into quarters

Open both cans of refrigerated cinnamon rolls and set the included icing aside for finishing. Separate all sixteen cinnamon rolls and cut each one into four pieces to create approximately sixty-four small dough sections. Place the cut pieces loosely on a wooden cutting board. Keep the cinnamon spirals visible while allowing some pieces to open slightly along their natural seams. The pieces should have irregular edges rather than perfectly identical shapes.

Tip: Keep the dough chilled until cutting so the cinnamon swirls hold their shape and the pieces do not become overly sticky.

Step 2: Whisk the vanilla cinnamon custard

Add four large eggs and one half cup of whole milk to a medium mixing bowl. Pour in the maple syrup along with the vanilla extract and ground cinnamon. Whisk until the eggs and milk become a smooth pale golden mixture with small cinnamon speckles throughout. The maple syrup should be fully incorporated and the custard should have a consistent liquid texture.

Tip: Whisk until the egg whites disappear into the milk so the casserole bakes with a smooth custard instead of separate eggy spots.

Step 3: Arrange the cinnamon rolls and pour over the custard

Preheat the oven to 350°F or 175°C and coat a 9 by 13 inch ceramic baking dish with the softened butter. Transfer all of the quartered cinnamon roll pieces into the prepared dish and spread them loosely across the bottom. Pour the cinnamon custard evenly over the pieces while allowing some of the golden liquid to collect between the dough sections. Gently reposition a few pieces so their cut edges touch the custard without pushing every piece below the surface. Let the casserole stand for about five minutes while the dough absorbs some of the liquid. The top should still show exposed cinnamon spirals and irregular dough peaks.

Tip: Leave some dough peaks above the custard so they bake golden while the lower portions become tender and creamy.

Step 4: Bake until puffed and golden brown

Place the assembled casserole in the preheated oven and bake for approximately thirty minutes. During baking the cinnamon roll pieces expand and the custard thickens into a tender filling around the dough. Remove the dish when the top is golden brown and the center is set rather than visibly liquid. The raised dough edges should show deeper caramelized color while the inner sections remain soft and pillowy. Allow the casserole to rest for approximately five minutes before adding the icing. This helps the custard finish setting and prevents the icing from disappearing completely into the hot surface.

Tip: Check the center before removing the casserole because the exposed rolls can brown before the custard underneath has fully set.

Step 5: Drizzle the warm casserole with vanilla icing

Open the reserved icing portions from both cinnamon roll packages. Allow the icing to reach room temperature so it spreads easily across the warm baked rolls. Drizzle the icing over the casserole in loose irregular ribbons. Let some icing settle into the cinnamon seams while keeping sections of the golden crust exposed for a homemade appearance. The finished casserole should have a contrast between the lightly browned dough and glossy white icing. Avoid spreading the icing into a completely smooth layer because the raised cinnamon rolls should remain visible.

Tip: Let the casserole cool slightly before adding icing so the drizzle stays visible instead of melting completely into the rolls.

Step 6: Serve a warm portion on a white plate

Cut the warm Cinnamon Roll Casserole into four generous servings. Carefully lift one portion from the baking dish and place it onto a white plate with the cinnamon swirls facing outward. The cut side should reveal the soft interior with distinct cinnamon layers and tender custard-soaked dough. Allow some of the vanilla icing to run naturally over the uneven edges while keeping the golden crust visible. Serve immediately while the center is warm and fluffy. The finished piece should hold together loosely while still showing its individual cinnamon roll sections.

Tip: Use a gentle lifting motion when serving so the tender cinnamon layers stay visible without compressing the soft center.

Pro Tips

• Use refrigerated cinnamon rolls that include icing so you can create the soft cinnamon base and sweet finishing drizzle easily.
• Cut each cinnamon roll into four pieces rather than tiny chunks so the casserole develops fluffy centers and golden raised edges.
• Spread the dough pieces loosely and leave a few exposed above the custard to create a delicious contrast of soft and crisp textures.
• Allow the casserole to rest for five minutes after baking so the custard sets and the icing stays visible on the warm surface.

Storage Instructions

Allow the Cinnamon Roll Casserole to cool before placing leftovers into an airtight container. Refrigerate the casserole within two hours of baking and keep it chilled at 40°F or below. Properly stored leftovers will stay fresh for up to three to four days. For individual portions cut the cooled casserole into serving-sized pieces and arrange them in shallow food-safe containers. Separate layers with parchment paper when stacking to prevent the icing from sticking.

Keep the containers tightly covered to preserve the soft texture. To freeze the casserole allow it to cool completely and wrap each portion tightly before transferring it to a freezer-safe container. Freeze for up to two months for the best quality. Thaw overnight in the refrigerator before reheating for more even results. To reheat a single refrigerated portion place it on a microwave-safe plate and warm in short intervals until heated through. For larger portions cover loosely with foil and warm in a 300°F oven until hot in the center.

An internal temperature of 165°F is a useful target for reheated leftovers. Add a little fresh icing only if desired. For holiday breakfast preparation you can cut the cinnamon rolls and mix the custard separately the evening before. Store both covered in the refrigerator and assemble the casserole just before baking. This approach helps prevent the dough from becoming overly soft during an extended overnight soak.
