Ingredients

Scale
  • 1 (12.2 ounce) can refrigerated cinnamon rolls
  • 4 large eggs
  • 1 cup milk
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 cup powdered sugar
  • 1 tablespoon milk

Instructions

  1. Separate the cinnamon rolls. Cut each roll into quarters.
  2. Place the cinnamon roll pieces in a greased 9×13 inch baking dish.
  3. In a medium bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, and ground cinnamon until well combined.
  4. Pour the egg mixture evenly over the cinnamon roll pieces in the baking dish.
  5. Cover the dish with plastic wrap and refrigerate overnight, or for at least 4 hours.
  6. Preheat your oven to 350°F (175°C).
  7. Remove the plastic wrap and bake for 25-30 minutes, or until the casserole is set and lightly golden brown.
  8. While the casserole is baking, prepare the icing. In a small bowl, whisk together the powdered sugar and 1 tablespoon of milk until smooth. Add more milk if needed to reach desired consistency.
  9. Once the casserole is out of the oven, drizzle the icing over the top.
  10. Serve warm.

Notes

  • For a gooey center, slightly underbake the casserole.
  • You can add chopped nuts or chocolate chips to the casserole before baking.
  • This casserole can also be made in a slow cooker on low for 2-3 hours.
