Make this gooey cinnamon breakfast casserole the night before for a simple, delicious morning treat. It uses canned dough for quick preparation.

Ingredients

Scale
  • 1 (12.4 ounce) can refrigerated jumbo cinnamon rolls (about 5 rolls)
  • 1 cup half-and-half
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon ground cinnamon
  • 1/4 cup packed light brown sugar
  • 2 tablespoons unsalted butter, melted
  • 1/4 cup powdered sugar (for icing)
  • 1 tablespoon milk (for icing)

Instructions

  1. Lightly grease an 8×8 inch baking dish.
  2. Arrange the cinnamon rolls close together in the prepared baking dish.
  3. In a medium bowl, whisk together the half-and-half, eggs, vanilla extract, and ground cinnamon until fully combined. This creates your custard base.
  4. In a separate small bowl, mix the brown sugar and melted butter until crumbly. Sprinkle this mixture evenly over the cinnamon rolls.
  5. Slowly pour the custard mixture over the cinnamon rolls, making sure to cover all the dough pieces.
  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 casserole is puffed and golden brown.
  9. While the casserole cools slightly, whisk together the powdered sugar and milk in a small bowl to create a simple glaze.
  10. Drizzle the icing over the warm cinnamon roll casserole before serving.

Notes

  • For a richer flavor, use heavy cream instead of half-and-half in the custard mixture.
  • If you want to bake this immediately without the overnight rest, let the assembled casserole sit at room temperature for 30 minutes before baking.
  • This recipe works well in a slow cooker on low for 3-4 hours if you prefer a crockpot cinnamon rolls method.
