A comforting and effortless cinnamon roll casserole that soaks overnight in a creamy custard, perfect for cozy mornings or busy days. This recipe uses simple ingredients and minimal prep for a warm, gooey breakfast treat.

Ingredients

Scale
  • 1 package (12 rolls) cinnamon rolls with icing
  • 4 large eggs, room temperature
  • 1 cup (240 ml) whole milk
  • 1/2 cup (120 ml) heavy cream
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt
  • Optional: 1/2 cup chopped nuts (pecans or walnuts)
  • For icing drizzle: pre-packaged icing from cinnamon rolls or homemade glaze (1/2 cup powdered sugar mixed with 1-2 tablespoons milk or cream)

Instructions

  1. Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Unroll and slice the cinnamon rolls into quarters or halves, then arrange evenly in the baking dish.
  3. In a mixing bowl, whisk together eggs, whole milk, heavy cream, vanilla extract, ground cinnamon, and salt until smooth.
  4. Pour the custard mixture evenly over the cinnamon roll pieces and press down gently to help absorption.
  5. Optional: sprinkle chopped nuts over the top.
  6. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  7. Preheat oven to 350°F (175°C). Remove casserole from fridge, uncover, and bake for 35-40 minutes until golden brown and custard is set. Tent with foil if edges brown too fast.
  8. Drizzle the included icing or homemade glaze over the casserole once out of the oven.
  9. Let the casserole rest for 5-10 minutes before slicing and serving warm.

Notes

Use room temperature eggs and dairy for smooth custard. Do not skip the overnight soak for best texture. Press rolls gently to avoid mushiness. Watch baking time and tent with foil if browning too fast. Let rest before serving for neater slices. For dairy-free or vegan options, substitute milk, cream, and eggs accordingly.
