This easy overnight cinnamon roll casserole is a quick and cozy breakfast that combines pre-made cinnamon rolls soaked in a rich custard, baked to golden perfection. It’s perfect for lazy mornings and delivers warm, gooey cinnamon goodness without the fuss of traditional rolls.

Ingredients

Scale
  • 8–10 standard size pre-made cinnamon rolls (e.g., Pillsbury) or homemade cinnamon rolls cut into chunks
  • 2 cups (480 ml) whole milk or 2% milk
  • 1 cup (240 ml) heavy cream (can substitute half-and-half)
  • 4 large eggs, room temperature
  • ½ cup (100 g) granulated sugar
  • 2 teaspoons vanilla extract
  • 2 teaspoons ground cinnamon
  • ¼ teaspoon salt
  • Optional glaze: 1 cup (120 g) powdered sugar, 2-3 tablespoons milk, ½ teaspoon vanilla extract

Instructions

  1. If baking immediately, preheat oven to 350°F (175°C). For overnight prep, refrigerate casserole first.
  2. Cut 8-10 cinnamon rolls into roughly 1-inch chunks using a sharp serrated knife.
  3. Spread cinnamon roll pieces evenly in a 9×13 inch casserole dish, leaving space for custard to seep in.
  4. In a large bowl, whisk together 4 large eggs, 2 cups milk, 1 cup heavy cream, ½ cup granulated sugar, 2 teaspoons vanilla extract, 2 teaspoons ground cinnamon, and ¼ teaspoon salt until smooth.
  5. Slowly pour custard mixture evenly over cinnamon roll chunks, pressing gently to help soak the pieces without floating.
  6. Cover dish tightly with plastic wrap or foil and refrigerate for at least 6 hours, preferably overnight.
  7. Remove casserole from fridge and let sit at room temperature for 10-15 minutes while preheating oven to 350°F (175°C).
  8. Bake uncovered for 40-45 minutes until top is golden brown and custard is set (toothpick inserted should come out clean).
  9. Optional: While baking, mix 1 cup powdered sugar, 2-3 tablespoons milk, and ½ teaspoon vanilla extract until smooth for glaze.
  10. Let casserole cool for 10 minutes after baking, then drizzle glaze on top and serve warm.

Notes

Do not skip refrigeration as it softens the rolls and blends flavors. Use room temperature eggs for smooth custard. If casserole is too wet after baking, reduce cream to ¾ cup or bake an extra 5 minutes. Let casserole rest a few minutes after baking for easier slicing. Cover casserole tightly in fridge to avoid drying out. For crispier edges bake uncovered; for softer edges tent with foil.
