A simple and comforting breakfast casserole made with canned cinnamon rolls soaked overnight in a cinnamon-spiced custard, baked to golden perfection and topped with icing.

Ingredients

Scale
  • 1 (12-ounce) can refrigerated cinnamon rolls with icing
  • 4 large eggs, room temperature
  • 1 cup whole milk
  • ½ cup packed brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 2 tablespoons melted unsalted butter

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish lightly with butter or non-stick spray.
  2. Cut each cinnamon roll into quarters using a knife or kitchen scissors.
  3. Arrange the cut cinnamon roll pieces evenly in the bottom of the prepared baking dish.
  4. In a large bowl, whisk together 4 large eggs, 1 cup whole milk, ½ cup packed brown sugar, 1 teaspoon vanilla extract, 1 teaspoon ground cinnamon, ¼ teaspoon salt, and 2 tablespoons melted butter until smooth and sugar starts to dissolve.
  5. Pour the custard mixture evenly over the cinnamon roll pieces, pressing gently to help them absorb the liquid.
  6. Cover the dish with plastic wrap or foil and refrigerate overnight or for at least 6 hours.
  7. Remove the casserole from the fridge and uncover. Bake in the preheated oven for 35-40 minutes, or until the custard is set and the top is golden brown. Check doneness with a toothpick; it should come out clean or with moist crumbs.
  8. While still warm, drizzle the included icing or a cream cheese glaze over the top. Optionally, sprinkle chopped nuts before baking or add fresh berries on the side.
  9. Let the casserole cool for 5 minutes before slicing and serving.

Notes

Use room temperature eggs and milk for a smooth custard. Soaking overnight is crucial for a tender, custardy texture. Tent with foil if the top browns too quickly. For vegan or dairy-free versions, substitute plant-based milk, flax eggs, and vegan butter. You can add nuts or fresh berries for extra texture and flavor.
