Ingredients You'll Need

Quality ingredients make all the difference here. Start with two 17.5-ounce tubes of refrigerated cinnamon rolls—any brand works, but choose the jumbo “Grands” style for maximum pillowy pockets. The accompanying icing packets will be reserved for the glaze, so don’t toss them! For the custard, you’ll need four large eggs at room temperature; cold eggs can cause the melted butter to seize, so set them out 30 minutes ahead. Whole milk delivers the silkiest texture, though 2% is acceptable in a pinch. Dark brown sugar deepens the molasses notes, but light brown works if that’s what’s in your pantry. A splash of pure vanilla extract and a whisper of maple extract (optional but heavenly) round out the flavors. Finally, ground cinnamon, a pinch of nutmeg, and a touch of salt balance the sweetness and heighten the cozy spice profile.

For the glaze, you’ll use the reserved icing packets, plus softened cream cheese for tang, a pat of butter for richness, and enough milk to reach pourable consistency. If you adore a thinner glaze, whisk in an extra tablespoon of milk at a time until it ribbons off the spoon like lava.

How to Make Cinnamon Roll Cinnamon Roll Casserole with Glaze Topping

Prep the Pan & Rolls

Preheat oven to 350°F (177°C). Grease a 9×13-inch baking dish with butter or non-stick spray. Pop open the cinnamon rolls and cut each into quarters. Scatter the pieces evenly in the dish, separating the layers slightly so the custard can seep between them.

Whisk the Custard

In a large bowl, whisk eggs until homogenous. Stream in melted butter, then brown sugar, cinnamon, nutmeg, and salt. Finally whisk in milk and both extracts until silky and fragrant.

Soak & Rest

Pour the custard over the cinnamon roll pieces. Press down gently with a spatula to submerge. Let stand 15 minutes (or cover and refrigerate up to 12 hours) so the bread can absorb the custard.

Bake to Gooey Perfection

Cover loosely with foil and bake 25 minutes. Remove foil and bake 15–20 minutes more, until the center puffs and a knife inserted comes out with just a few moist crumbs. Rest 10 minutes to set.

Make the Glaze

While the casserole bakes, beat reserved icing packets with cream cheese and butter until smooth. Thin with milk 1 tablespoon at a time until pourable yet opaque.

Drizzle & Serve

Drizzle glaze generously over the warm casserole. Scoop into bowls and serve immediately, preferably with hot coffee or a glass of cold milk.

Expert Tips

Room-Temp Eggs

Cold eggs can cause the melted butter to seize, creating tiny flecks. Let eggs sit on the counter 30 minutes or submerge in warm water for 5 minutes.

Overnight Option

Assemble through step 3, cover tightly, and refrigerate up to 12 hours. Add 5–10 minutes to the covered bake time if starting cold.

Crunchy Top Hack

Sprinkle ¼ cup coarse sugar or crushed cornflakes mixed with 1 tablespoon melted butter over the top before baking for a caramelized crunch.

Glaze Consistency

For a thick icing that sets like Cinnabon’s, use only 1 tablespoon milk. For a pourable glaze that pools in the nooks, use up to 3 tablespoons.

Variations to Try

Storage Tips

Cool leftovers completely, then cover tightly or transfer to airtight containers. Refrigerate up to 4 days. To reheat, microwave individual portions 30–45 seconds or warm the whole pan, covered with foil, at 300°F for 15 minutes. For longer storage, freeze portions in freezer-safe bags up to 2 months. Thaw overnight in the fridge, then reheat as above. Note: the glaze may melt into the casserole upon reheating; simply whip up a fresh batch if you crave that glossy finish.

Frequently Asked Questions

Absolutely! Use about 1½ pounds of baked cinnamon rolls, cut into 1-inch cubes. Day-old rolls work best because they soak up custard without becoming mushy.

Yes—halve all ingredients and bake in an 8×8-inch dish. Start checking for doneness at 25 minutes.

Not as written, but you can substitute gluten-free refrigerated cinnamon rolls and ensure all other ingredients are certified gluten-free.

Yes. Oat milk or full-fat coconut milk (the drinking kind, not canned) yields the creamiest results.

Under-baking is the usual culprit. Bake until the center springs back lightly and internal temp hits 185°F. If the top browns too quickly, tent with foil and continue baking.
