Ingredients Method Notes

Ingredients
  

  • 2 cans refrigerated cinnamon rolls with icing approximately 12–16 rolls total
  • 4 large eggs
  • ½ cup heavy cream
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 2 tablespoons packed brown sugar
  • 2 tablespoons pure maple syrup
  • Pinch of salt
  • 1 tablespoon softened butter for greasing
  • ½ cup roughly chopped pecans optional
  • Reserved cinnamon roll icing for finishing

Method
 

  1. Preheat oven to 350°F (175°C).
  2. Grease a 9 × 13-inch baking dish with softened butter.
  3. Open the cinnamon rolls and reserve the icing.
  4. Cut each unbaked cinnamon roll into four pieces.
  5. Scatter the pieces evenly throughout the baking dish without tightly packing them.
  6. Whisk eggs, heavy cream, vanilla, cinnamon, brown sugar, maple syrup, and salt.
  7. Pour the mixture evenly over the cinnamon-roll pieces.
  8. Sprinkle with chopped pecans if using.
  9. Rest for 5–10 minutes.
  10. Bake uncovered for 25–35 minutes, until puffed and golden and the center is fully set.
  11. Cover loosely with foil if the top browns before the center finishes baking.
  12. Cool for 5–10 minutes.
  13. Drizzle with the reserved icing.
  14. Serve warm.

Notes

  • Keep the cinnamon rolls refrigerated until you're ready to cut them.
  • Pecans are optional for a more kid-friendly version.
  • Whole milk can replace heavy cream for a lighter casserole.
  • Don't completely submerge the cinnamon-roll pieces in custard.
  • Check the center for doneness rather than relying only on the browned top.
  • Let the casserole cool briefly before adding the icing.
