Make this easy, make ahead breakfast casserole using store-bought cinnamon rolls for a decadent weekend breakfast treat. It bakes into a gooey cinnamon roll fusion recipe perfect for brunch.

Ingredients

Scale
  • 1 (12.7 ounce) package refrigerated cinnamon rolls (about 8 rolls)
  • 6 large eggs
  • 1 cup half and half or whole milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 cup granulated sugar
  • 1/4 cup brown sugar, packed
  • 1/2 cup water
  • 1 tablespoon cornstarch
  • 1/4 cup butter, melted
  • Cream cheese icing packet from the cinnamon rolls

Instructions

  1. Lightly grease a 9×13 inch baking dish.
  2. Separate the cinnamon rolls and place them evenly in the prepared baking dish. Do not separate the icing packets.
  3. In a large bowl, whisk together the eggs, half and half, vanilla extract, and ground cinnamon until well combined.
  4. Pour the egg mixture evenly over the cinnamon rolls in the baking dish. Gently press down on the rolls to help them absorb the custard.
  5. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight.
  6. When ready to bake, preheat your oven to 350 degrees Fahrenheit. Remove the plastic wrap.
  7. In a small saucepan, combine the water, cornstarch, granulated sugar, brown sugar, and melted butter. Whisk constantly over medium heat until the mixture thickens slightly, about 3 to 5 minutes. This creates your simple syrup glaze.
  8. Pour the warm glaze evenly over the soaked cinnamon rolls.
  9. Bake for 30 to 35 minutes, or until the casserole is puffed and golden brown in the center.
  10. Remove the casserole from the oven. Immediately open the icing packets and drizzle the cream cheese icing over the hot casserole.
  11. Let the casserole cool for 10 minutes before slicing and serving this sweet breakfast comfort food.

Notes

  • For an extra decadent flavor, substitute the half and half with heavy cream.
  • If you do not want to make the simple syrup glaze, you can simply bake the casserole and then microwave the icing packets separately to drizzle on top when done.
  • This recipe works well with King’s Hawaiian rolls if you prefer a smaller, sweeter base bread.
