This gooey, pull-apart casserole transforms canned cinnamon rolls into a warm, shareable feast. It is perfect for lazy weekend mornings, holiday brunches, or feeding overnight guests with minimal effort. The result is a comforting, custardy bake with a caramelized cinnamon-sugar topping, finished with a sweet icing drizzle.

Ingredients

Scale
  • 2 cans (12.4 oz each) refrigerated cinnamon rolls with icing
  • 4 large eggs
  • 1/2 cup heavy cream or whole milk
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 pinch salt
  • 1/2 cup chopped pecans or walnuts (optional)
  • 1/2 cup packed light brown sugar
  • 4 tablespoons unsalted butter, melted

Instructions

  1. Preheat oven to 375°F (190°C). Generously grease a 9×13 inch baking dish.
  2. Open cinnamon roll cans and set icing packets aside. Cut each roll into 6-8 pieces and scatter evenly in the prepared dish.
  3. In a large bowl, whisk eggs until frothy. Add cream, vanilla, cinnamon, nutmeg, and salt. Whisk until smooth.
  4. Pour egg mixture evenly over the cinnamon roll pieces. Gently press down with a spatula to help soaking.
  5. In a small bowl, stir melted butter and brown sugar into a paste. Dollop over the casserole. Sprinkle with nuts if using.
  6. Bake for 35-40 minutes, until top is golden brown, edges are bubbling, and a knife inserted in center comes out clean.
  7. Let cool for 5-10 minutes. Drizzle with reserved icing and serve warm.

Notes

For make-ahead, assemble the unbaked casserole, cover, and refrigerate overnight. Bake as directed, adding 5-10 minutes if starting cold. Leftovers reheat well. For a lighter version, use milk instead of cream and reduce the brown sugar topping.
