Ingredients

Scale
  • 8 refrigerated cinnamon rolls (with icing included preferred)
  • 6 large eggs, room temperature
  • 2 cups (480 ml) whole milk
  • 1 cup (240 ml) heavy cream
  • 1/4 cup (50 g) granulated sugar
  • 2 teaspoons ground cinnamon
  • 1 tablespoon pure vanilla extract
  • 1/4 teaspoon salt
  • 2 tablespoons melted butter (optional, for greasing the dish)
  • 1 cup (120 g) powdered sugar (for glaze)
  • 23 tablespoons milk (for glaze)
  • Optional: 1/2 cup chopped pecans or walnuts

Instructions

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Slice each cinnamon roll into halves or thirds to create bite-sized pieces and place them evenly in the greased baking dish.
  3. In a large mixing bowl, whisk together 6 large eggs, 2 cups whole milk, 1 cup heavy cream, 1/4 cup granulated sugar, 2 teaspoons ground cinnamon, 1 tablespoon vanilla extract, and 1/4 teaspoon salt until fully combined and slightly frothy.
  4. Slowly pour the custard mixture over the cinnamon roll pieces, pressing down gently with a spatula to encourage absorption.
  5. Cover the dish with plastic wrap and refrigerate for at least 2 hours or overnight for best results.
  6. Remove the casserole from the fridge and let it sit at room temperature for 15 minutes.
  7. Bake in the preheated oven for 40-45 minutes or until the top is golden brown and a knife inserted near the center comes out clean.
  8. While baking, whisk together 1 cup powdered sugar with 2-3 tablespoons milk until smooth and drizzle-able. Add more milk if needed to thin the glaze.
  9. Let the casserole cool for 10 minutes after baking, then drizzle the glaze evenly on top and optionally sprinkle with chopped pecans or walnuts.
  10. Serve warm.

Notes

For best texture, soak the cinnamon rolls in custard overnight or at least 2 hours. Tent with foil if edges brown too fast. Use fresh ground cinnamon for best flavor. Glaze consistency should be smooth but not too runny. Can be adapted for gluten-free or vegan diets with substitutions.
