Create a decadent, shareable breakfast using store-bought cinnamon rolls. This make-ahead casserole soaks rolls in custard overnight, resulting in a gooey, sweet French toast bake perfect for brunch gatherings.

Ingredients

Scale
  • 1 (12.7 ounce) package refrigerated cinnamon rolls (about 8 rolls)
  • 6 large eggs
  • 1 1/2 cups whole milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 cup granulated sugar
  • 1/4 cup brown sugar, packed
  • 1/4 cup heavy cream (optional, for richer custard)
  • Cream cheese icing packet included with rolls

Instructions

  1. Grease a 9×13 inch baking dish with butter or cooking spray.
  2. Cut each cinnamon roll into quarters. Arrange the pieces evenly in the prepared baking dish.
  3. In a large bowl, whisk together the eggs, milk, vanilla extract, ground cinnamon, granulated sugar, brown sugar, and heavy cream until well combined. This is your custard base.
  4. Slowly pour the custard mixture evenly over the cinnamon roll pieces in the baking dish, ensuring all pieces are coated. Gently press down on the rolls to help them absorb the liquid.
  5. Cover the baking dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight, to allow the rolls to soak up the custard.
  6. When ready to bake, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Remove the plastic wrap.
  7. Bake for 30 to 35 minutes, or until the casserole is puffed, golden brown, and set in the center.
  8. Remove the casserole from the oven and let it cool for 5 minutes.
  9. While the casserole cools slightly, prepare the icing according to package directions, thinning it slightly with a teaspoon of milk if needed for drizzling.
  10. Drizzle the cream cheese icing generously over the warm cinnamon roll french toast casserole before serving.

Notes

  • For extra gooeyness, reserve the icing that comes with the rolls and use it immediately after baking.
  • If you prefer a crispier top, uncover the casserole for the last 10 minutes of baking.
  • This recipe works well with brioche bread cubes if you want to make it completely from scratch instead of using canned rolls.
