Ingredients
Scale
- 8 large store-bought cinnamon rolls with icing
- 1 ½ cups whole milk (360 ml)
- 3 large eggs, room temperature
- ⅓ cup granulated sugar (65 g)
- 1 teaspoon pure vanilla extract
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- Cream cheese frosting (included with cinnamon rolls or homemade)
Instructions
- Grease a 9×13-inch baking dish with butter or nonstick spray. Optionally, line with parchment paper.
- Separate the cinnamon rolls and place them evenly spaced in the baking dish.
- In a mixing bowl, whisk together whole milk, eggs, sugar, vanilla extract, ground cinnamon, and salt until smooth and slightly frothy.
- Pour the custard mixture evenly over the cinnamon rolls. Gently press the rolls down to soak up the custard.
- Cover the dish tightly with aluminum foil or plastic wrap and refrigerate overnight (at least 6 hours).
- Preheat oven to 350°F (175°C). Remove the casserole from the fridge and uncover.
- Bake uncovered for 45-50 minutes until the top is golden brown and custard is set (edges puff slightly and center does not jiggle).
- Let the casserole cool for 10 minutes, then drizzle cream cheese frosting over the warm casserole.
- Serve warm and enjoy.
Notes
Do not skip the overnight soak for best texture. Use whole milk for creaminess. Press rolls gently into custard to avoid dry pockets. Cover with foil if top browns too fast. Leftover frosting can be frozen. Reheat slices in microwave or oven.
