Prepare this simple cinnamon roll casserole the night before for an easy, gooey cinnamon breakfast bake when you wake up.

Ingredients

Scale
  • 1 (12.5 ounce) package refrigerated cinnamon rolls with icing
  • 4 large eggs
  • 1 cup whole milk
  • 1 teaspoon vanilla extract
  • 1/4 cup granulated sugar
  • 1/2 teaspoon ground cinnamon
  • 1/4 cup chopped pecans (optional)

Instructions

  1. Lightly grease a 9×13 inch baking dish.
  2. Arrange the refrigerated cinnamon rolls in a single layer in the prepared baking dish. Cut any rolls that do not fit flat into halves or thirds to fill the space.
  3. In a medium bowl, whisk together the eggs, milk, vanilla extract, granulated sugar, and ground cinnamon until well combined. This creates your custard base.
  4. Pour the custard mixture evenly over the cinnamon rolls in the baking dish. Gently press down on the rolls to help them absorb the liquid.
  5. If using, sprinkle the chopped pecans over the top.
  6. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight.
  7. When ready to bake, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Remove the plastic wrap.
  8. Bake for 30 to 35 minutes, or until the casserole is puffed and golden brown in the center.
  9. Remove from the oven and let it cool for 5 minutes.
  10. Warm the icing packets that came with the rolls and drizzle generously over the warm casserole before serving.

Notes

  • For a crockpot cinnamon rolls version, assemble the casserole as directed, cover the slow cooker insert with foil before placing the lid on, and cook on low for 4 to 5 hours.
  • If you need a faster bake, let the casserole sit at room temperature for 30 minutes after removing it from the refrigerator before placing it in the oven.
  • This recipe uses canned dough for an easy brunch bake experience.
