Cinnamon Roll Casserole Recipe
Introduction
This Cinnamon Roll Casserole is a delightful twist on the classic breakfast treat, perfect for feeding a crowd or enjoying leftovers throughout the week. Soft cinnamon rolls baked in a creamy egg mixture create a warm, comforting dish topped with sweet frosting. It’s an easy and impressive way to start your day.

Ingredients
- 2 tablespoons butter (melted)
- 2 (17.5 oz) cans Pillsbury Grands cinnamon rolls (or 8 count regular size)
- 1/2 cup whole milk
- 1 teaspoon vanilla extract
- 1 tablespoon ground cinnamon
- 4 large eggs
Instructions
- Step 1: Preheat your oven to 350°F and set the frosting from the cinnamon rolls aside to use later.
- Step 2: Coat a 9×13 glass baking dish with the melted butter. Use a knife or kitchen shears to cut the cinnamon rolls into 1-inch pieces and place them evenly in the baking dish. Keep the icing for topping after baking.
- Step 3: In a bowl, whisk together the milk, vanilla extract, ground cinnamon, and eggs until well combined with no clumps of cinnamon remaining.
- Step 4: Pour the egg mixture evenly over the cinnamon roll pieces. Bake for 30 to 35 minutes, until the top is golden brown and the center is set without any jiggle.
- Step 5: Remove from the oven and spread the reserved frosting over the warm casserole. Serve immediately and enjoy! For extra sweetness, try topping with cream cheese frosting.
Tips & Variations
- Use regular cinnamon rolls instead of grands for a smaller, denser casserole texture.
- For a richer flavor, substitute half-and-half for the whole milk.
- Add a handful of chopped nuts or raisins to the cinnamon roll pieces before baking for added texture.
- Make cream cheese frosting from scratch for an extra indulgent topping.
