Prepare this simple cinnamon roll casserole the night before for a warm, gooey breakfast bake ready when you wake up.

Ingredients

Scale
  • 1 (12.4 ounce) package refrigerated cinnamon rolls (about 8 rolls)
  • 4 large eggs
  • 1 cup milk
  • 1 teaspoon vanilla extract
  • 1/4 cup granulated sugar
  • 1/2 teaspoon ground cinnamon
  • 1 (8 ounce) package cream cheese, softened
  • 1/2 cup powdered sugar
  • 2 tablespoons milk

Instructions

  1. Lightly grease a 9×13 inch baking dish.
  2. Cut each refrigerated cinnamon roll into quarters.
  3. Arrange the cut pieces evenly in the prepared baking dish.
  4. In a medium bowl, whisk together the eggs, 1 cup milk, vanilla extract, granulated sugar, and 1/2 teaspoon cinnamon until combined.
  5. Pour the egg mixture evenly over the cinnamon roll pieces in the dish.
  6. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight.
  7. When ready to bake, preheat your oven to 350 degrees Fahrenheit. Remove the plastic wrap.
  8. Bake for 30 to 35 minutes, or until the custard is set and the top is golden brown.
  9. While baking, prepare the icing: Beat the softened cream cheese, powdered sugar, and 2 tablespoons milk until smooth.
  10. Remove the casserole from the oven and let it cool for 10 minutes.
  11. Drizzle the cream cheese icing over the warm casserole before serving.

Notes

  • For a slow-cooker version, place the assembled casserole in a lightly greased slow cooker. Cook on low for 3 to 4 hours.
  • If you want a richer flavor, use heavy cream instead of milk in the custard mixture.
  • This recipe uses canned dough for quick preparation.
