Ingredients

Scale
  • 1 (12-count) package refrigerated cinnamon rolls
  • 4 large eggs, room temperature
  • 1 cup whole milk (or substitute with almond milk for dairy-free)
  • 1/2 cup heavy cream (or coconut cream as substitute)
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract (optional)
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • Powdered sugar glaze (included in cinnamon roll package or homemade with powdered sugar and milk)

Instructions

  1. Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Cut each refrigerated cinnamon roll into quarters and spread evenly in the baking dish, filling gaps but not overcrowding.
  3. In a mixing bowl, whisk together 4 large eggs, 1 cup whole milk, 1/2 cup heavy cream, 1/4 cup granulated sugar, 1 teaspoon vanilla extract, 1 teaspoon ground cinnamon, and 1/4 teaspoon salt until smooth and slightly frothy.
  4. Slowly pour the custard mixture evenly over the cinnamon roll pieces, pressing down gently with a spatula to help the rolls absorb the liquid. Do not stir.
  5. Cover the dish tightly with aluminum foil and refrigerate for at least 8 hours or overnight.
  6. Preheat oven to 350Β°F (175Β°C). Remove foil and bake uncovered for 35-40 minutes, or until the top is golden brown and custard is set (a knife inserted in the center should come out clean). If the top browns too quickly, loosely tent with foil.
  7. Once slightly cooled (about 10 minutes), drizzle the included glaze or homemade powdered sugar glaze over the casserole. Cut into squares and serve warm.

Notes

Use room temperature eggs for a smooth custard. Do not overcrowd the cinnamon roll pieces to ensure even baking and soaking. Cover tightly overnight to prevent drying out. Check baking at 30 minutes to avoid overbaking. Drizzle glaze while casserole is warm for best absorption. The overnight soak is key for perfect texture. Variations include gluten-free cinnamon rolls, adding fruit or nuts, and vegan substitutions.
