A quick and easy overnight cinnamon roll casserole that combines refrigerated cinnamon rolls with a creamy custard soak, perfect for cozy mornings and busy schedules.

Ingredients

Scale
  • 1 can (8 rolls) refrigerated cinnamon rolls with icing included
  • 4 large eggs, beaten
  • 1 cup (240 ml) whole milk
  • ½ cup (120 ml) heavy cream (optional but recommended)
  • 1 teaspoon vanilla extract
  • 2 teaspoons ground cinnamon
  • 2 tablespoons brown sugar
  • a pinch of salt
  • 2 tablespoons butter, melted

Instructions

  1. Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Open the can of refrigerated cinnamon rolls and separate them. Place evenly spaced in the baking dish.
  3. In a medium bowl, whisk together eggs, whole milk, heavy cream, vanilla extract, ground cinnamon, brown sugar, and salt until smooth.
  4. Pour the custard mixture evenly over the cinnamon rolls, ensuring they are fully soaked.
  5. Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate overnight or at least 6 hours.
  6. The next morning, preheat oven to 350°F (175°C). Remove casserole from fridge and let sit at room temperature for 15 minutes.
  7. Brush the tops of the rolls with melted butter.
  8. Bake uncovered for 35-40 minutes until golden brown and custard is set (toothpick should come out mostly clean).
  9. Drizzle the included icing over the casserole while still warm.
  10. Slice into squares and serve immediately.

Notes

Let the casserole soak overnight for the best soft and custardy texture. Let it sit 15 minutes at room temperature before baking to ensure even cooking. Brush melted butter on top before baking for a golden crust. Tent with foil if browning too fast. Optional toppings include chopped nuts, fresh berries, or powdered sugar dusting.
