Prepare this easy brunch bake the night before for a gooey cinnamon breakfast treat ready when you wake up. This simple recipe uses canned dough for minimal morning effort.

Ingredients

Scale
  • 1 (12.7 ounce) package refrigerated cinnamon rolls with icing
  • 1 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 large egg
  • 1/2 cup milk
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • 4 ounces cream cheese, softened
  • 1/4 cup powdered sugar

Instructions

  1. Lightly grease a 9×13 inch baking dish.
  2. Cut each refrigerated cinnamon roll into quarters. Arrange the pieces evenly in the prepared baking dish.
  3. In a medium bowl, whisk together the flour, granulated sugar, baking powder, and salt.
  4. In a separate bowl, whisk the egg, milk, melted butter, and vanilla extract until combined.
  5. Pour the wet ingredients over the dry ingredients and mix until just combined; do not overmix.
  6. Pour the custard mixture evenly over the cinnamon roll pieces in the baking dish.
  7. Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight.
  8. When ready to bake, preheat your oven to 350 degrees Fahrenheit. Remove the plastic wrap.
  9. Bake for 30 to 35 minutes, or until the casserole is set and lightly golden brown.
  10. While the casserole bakes, prepare the drizzle: Beat the softened cream cheese until smooth. Gradually beat in the powdered sugar until you reach a smooth consistency. Add a teaspoon of milk if the icing is too thick.
  11. Remove the casserole from the oven and let it cool for 10 minutes. Drizzle the cream cheese icing over the warm casserole before serving.

Notes

  • For a slow-cooker cinnamon rolls option, assemble the casserole as directed, cover, and cook on low for 3 to 4 hours.
  • If you prefer a richer flavor, substitute heavy cream for the milk in the custard mixture.
  • This recipe works well as a 5 ingredient cinnamon casserole if you skip making the homemade cream cheese drizzle and use the icing packets provided with the rolls.
