Print Recipe

A simple and indulgent breakfast casserole made by layering cinnamon rolls with a custard soak overnight, then baking to a gooey, bakery-fresh delight.

Ingredients

Scale
  • 12-count package of pre-made cinnamon rolls with icing included
  • 2 cups whole milk, room temperature
  • 4 large eggs, room temperature
  • 1/2 cup packed brown sugar
  • 1 teaspoon vanilla extract
  • 2 teaspoons ground cinnamon
  • 1/4 teaspoon nutmeg (optional)
  • Pinch of salt (about 1/8 teaspoon)
  • Optional: chopped pecans or walnuts for topping
  • Optional glaze: powdered sugar mixed with a splash of milk

Instructions

  1. Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
  2. Unroll cinnamon rolls and cut each into quarters or smaller pieces. Spread evenly in the prepared dish, pressing lightly to fit snugly but leaving air pockets.
  3. In a medium bowl, whisk together milk, eggs, brown sugar, vanilla extract, ground cinnamon, nutmeg (if using), and salt until smooth and lump-free.
  4. Pour the custard evenly over the cinnamon roll pieces. Use a spatula to gently press some pieces down so the custard soaks in well.
  5. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  6. Preheat oven to 350°F (175°C). Remove casserole from fridge and uncover.
  7. Bake uncovered for 35 to 40 minutes until the top is golden brown and custard is set (a knife inserted near the center should come out clean).
  8. If desired, drizzle the included icing packet or prepared glaze over the warm casserole after baking.
  9. Serve warm.

Notes

Letting the custard soak overnight is crucial for a soft, custardy texture. Tent with foil if the top browns too quickly. Adding chopped nuts before baking adds crunch. Use gluten-free or dairy-free substitutes as needed.
