Ingredients

2 cans refrigerated cinnamon rolls (about 12 rolls total)
5 large eggs
1/2 cup milk
1/4 cup heavy cream
1 teaspoon vanilla extract
1 teaspoon ground cinnamon
2 tablespoons melted butter
1/4 cup brown sugar
1/2 cup chopped pecans (optional)
Icing from the cinnamon roll packages

Instructions

Grease a 9×13-inch baking dish with butter or cooking spray.

Open the cinnamon roll packages and set the icing aside. Cut each cinnamon roll into quarters and spread the pieces evenly in the prepared baking dish.

In a medium bowl, whisk together the eggs, milk, heavy cream, vanilla extract, and cinnamon.

Pour the egg mixture evenly over the cinnamon roll pieces.

Drizzle the melted butter over the top. Sprinkle with brown sugar and chopped pecans, if using.

Cover the baking dish tightly with plastic wrap or foil and refrigerate overnight.

In the morning, remove the casserole from the refrigerator while the oven preheats to 350 degrees F.

Remove the cover and bake for 35–40 minutes, or until the center is set and the cinnamon roll pieces are golden brown. If the top starts browning too quickly, loosely cover it with foil.

Let the casserole rest for about 5 minutes. Warm the reserved icing slightly and drizzle it over the top before serving.

Serve warm!

Tips for Making Overnight Cinnamon Roll Casserole

Use a little extra icing. If you love the sweet glaze on cinnamon rolls, you can add a little powdered sugar and milk to the packaged icing to make more.

Check the center before serving. The top may look done before the middle is fully baked. Make sure the center is set before taking the casserole out of the oven.

Add your favorite toppings. Chopped pecans or walnuts add a nice crunch. You could also sprinkle a little extra cinnamon sugar over the top before baking.

Let it rest. Give the casserole a few minutes to cool before serving. This helps it set up and makes it easier to scoop.

Can You Make Cinnamon Roll Casserole Ahead of Time?

Yes! That’s the best part of this recipe.

Prepare the casserole the evening before, cover it tightly, and refrigerate overnight. In the morning, bake it according to the directions.

For the best results, keep the icing separate until after baking. You can warm it slightly before drizzling it over the finished casserole.

How to Store Leftovers

Store leftover cinnamon roll casserole in an airtight container in the refrigerator for up to 3 days.

Reheat individual servings in the microwave until warmed through. You can add a little extra icing before serving if you like.

What to Serve with Cinnamon Roll Casserole

This sweet breakfast casserole is delicious served with fresh fruit, scrambled eggs, bacon, or breakfast sausage.

If you’re serving Christmas morning brunch, you could also set out a bowl of fresh berries and a pot of coffee or hot chocolate.
