A warm, sweet, and comforting breakfast casserole made by soaking cinnamon rolls overnight in a vanilla-cinnamon egg custard and baking to golden perfection. Perfect for busy mornings or cozy weekends.

Ingredients

Scale
  • 1 package (about 8 count) refrigerated cinnamon rolls
  • 6 large eggs, room temperature
  • 1 ½ cups whole milk (360 ml)
  • ½ cup heavy cream (120 ml)
  • 1 tablespoon pure vanilla extract
  • 2 tablespoons granulated sugar
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • Optional: ¼ cup chopped pecans or walnuts
  • Powdered sugar or icing glaze for topping after baking

Instructions

  1. Preheat oven to 350°F (175°C). Open the package of cinnamon rolls and cut each roll into roughly 1-inch pieces.
  2. Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Spread the cinnamon roll pieces evenly in the dish.
  3. In a large mixing bowl, whisk together eggs, whole milk, heavy cream, vanilla extract, sugar, cinnamon, and salt until fully combined and slightly frothy.
  4. Pour the custard mixture over the cinnamon roll pieces, pressing gently to ensure all pieces soak up the liquid.
  5. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  6. The next morning, bake uncovered at 350°F (175°C) for 35–40 minutes until the top is golden brown and a knife inserted comes out mostly clean. Cover edges with foil if browning too fast.
  7. Let cool for 5 minutes, then drizzle with icing or dust with powdered sugar. Add chopped nuts if desired. Serve warm.

Notes

Use room temperature eggs and milk for even soaking. Do not skip the overnight soak for best texture. Cover edges with foil if browning too fast. Butter or spray the baking dish to prevent sticking. Can substitute almond milk for dairy-free option and flax eggs for vegan adaptation.
