Ingredients

Scale
  • 1 package (12 rolls) classic cinnamon rolls with icing (Pillsbury recommended)
  • 1 cup whole milk (240 ml)
  • 3 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1 cup powdered sugar (120 g), sifted
  • 2 tablespoons unsalted butter, melted
  • 2 tablespoons whole milk (30 ml)
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish lightly with butter or nonstick spray to prevent sticking.
  2. Unwrap the cinnamon rolls and cut each into quarters to create bite-sized pieces.
  3. In a mixing bowl, whisk together 1 cup whole milk, 3 large eggs, 2 teaspoons vanilla extract, and ½ teaspoon ground cinnamon until fully combined and slightly frothy.
  4. Spread the cinnamon roll pieces evenly in the prepared baking dish. Pour the custard mixture over the top, ensuring every piece is soaked. Press down lightly with a spatula.
  5. Bake for 30 to 35 minutes until the casserole puffs up and turns golden brown. A toothpick inserted near the center should come out clean.
  6. While baking, combine 1 cup powdered sugar, 2 tablespoons melted butter, 2 tablespoons milk, and 1 teaspoon vanilla extract in a small bowl. Whisk until smooth and glossy. Adjust milk for desired glaze consistency.
  7. Remove casserole from oven and let cool for about 5 minutes. Drizzle the vanilla glaze generously over the warm casserole.
  8. Serve warm and enjoy.

Notes

Use room temperature eggs for best custard texture. Tent casserole with foil if top browns too quickly. Prep glaze while casserole bakes to save time. For dairy-free, swap milk and butter with plant-based alternatives. Gluten-free cinnamon rolls can be used if available.
