Overnight Cinnamon Roll Casserole – The Recipe

Ingredients:

• 2 cans (12.4 oz each) refrigerated cinnamon rolls with icing

• 4 large eggs

• 1/2 cup heavy cream (or whole milk)

• 2 tsp vanilla extract

• 1–2 tsp ground cinnamon

• 1/4 cup maple syrup (optional, for extra richness)

Instructions:

1. Prepare the baking dish:
   Grease a 9x13-inch baking dish with butter or cooking spray.

2. Cut and layer the cinnamon rolls:
   Open the cinnamon roll cans and set the icing aside. Cut each roll into quarters. Spread the pieces evenly in the prepared baking dish. Sprinkle with nuts if using.

3. Mix the custard:
   In a medium bowl, whisk together the eggs, cream, vanilla, cinnamon, and maple syrup (if using). Pour this mixture evenly over the cinnamon roll pieces.

4. Cover and refrigerate overnight:
   Cover the dish tightly with foil or plastic wrap and refrigerate overnight (or for at least 6 hours).

5. Bake the next morning:
   Preheat the oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature while the oven heats. Bake uncovered for 35–40 minutes, or until golden brown and cooked through.

6. Add the icing:
   Warm the reserved icing slightly in the microwave and drizzle over the casserole right after baking. Serve warm.
