Print Recipe

A quick and comforting cinnamon roll casserole soaked overnight in a rich custard and topped with homemade cream cheese frosting. Perfect for busy mornings or special gatherings.

Ingredients

Scale
  • One 12-count package store-bought cinnamon rolls (preferably Pillsbury)
  • 4 large eggs, room temperature
  • 1 cup whole milk (240 ml) or half-and-half for richer custard
  • ½ cup heavy cream (120 ml), optional but recommended
  • ¼ cup granulated sugar (50 g)
  • 1 teaspoon vanilla extract
  • 1 teaspoon cinnamon
  • 4 oz cream cheese, softened
  • 1 cup powdered sugar (120 g), sifted
  • 2 tablespoons butter, softened
  • 1–2 tablespoons milk (for frosting)

Instructions

  1. Unroll the cinnamon rolls and cut each into quarters. Place the pieces evenly in a greased 9×13-inch baking dish.
  2. In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, vanilla extract, and cinnamon until smooth.
  3. Pour the custard evenly over the cinnamon roll pieces, pressing lightly to cover all pieces. Cover tightly with plastic wrap or foil and refrigerate overnight (at least 6 hours).
  4. Preheat oven to 350°F (175°C). Remove casserole from fridge and let sit at room temperature for 10 minutes.
  5. Bake uncovered for 35-40 minutes until the top is golden brown and custard is set (toothpick should come out clean).
  6. While baking, beat cream cheese, butter, powdered sugar, and milk until smooth and spreadable.
  7. Remove casserole from oven and let cool 5-10 minutes. Spread or drizzle cream cheese frosting over warm casserole and serve.

Notes

Use room temperature eggs and milk for smooth custard. Do not skip the overnight soak for best texture. Tent with foil if top browns too quickly. Spread frosting while casserole is warm but not hot. For extra gooeyness, add chopped pecans or walnuts before baking. Can substitute almond or oat milk and dairy-free cream cheese for dairy-free version. Gluten-free cinnamon rolls can be used for gluten-free adaptation.
