Ingredients
Scale
- 12 count pre-made cinnamon rolls (classic or large)
- 1 cup (240 ml) whole milk or milk of choice (dairy or plant-based)
- 3 large eggs, room temperature
- 1/2 cup (100 g) granulated sugar
- 1/3 cup (67 g) packed brown sugar
- 4 tablespoons (57 g) unsalted butter, melted
- 1 teaspoon vanilla extract
- 2 teaspoons ground cinnamon
- 1/2 cup (120 g) cream cheese frosting (store-bought or homemade, optional but recommended)
Instructions
- Lightly grease a 9×13 inch (23×33 cm) baking dish with butter or non-stick spray.
- Cut the cinnamon rolls into quarters and spread evenly in the baking dish.
- In a medium bowl, whisk together eggs, milk, granulated sugar, brown sugar, melted butter, vanilla extract, and ground cinnamon until smooth and sugar is mostly dissolved.
- Dollop spoonfuls of cream cheese frosting over the cinnamon roll pieces.
- Slowly pour the custard mixture over the cinnamon roll pieces, pressing gently with a spatula to help them absorb the liquid. Let sit for a few minutes.
- Cover the dish tightly with plastic wrap or foil and refrigerate overnight (8+ hours).
- Preheat oven to 350°F (175°C). Remove plastic wrap and bake uncovered for 35-40 minutes until top is golden brown and custard is set but still soft in the center.
- Let the casserole rest for 5-10 minutes before serving to set and maintain gooey texture.
Notes
If edges brown too quickly, tent loosely with foil halfway through baking. For extra gooeyness, drizzle warmed cream cheese frosting or maple syrup before serving. Use room temperature eggs for better custard texture. Overnight soak is essential for moist, gooey casserole. Dairy-free and gluten-free substitutions are possible with appropriate ingredient swaps.
