Prep Time: 10 minutes

Cook Time: 28–32 minutes

Yield: 8 servings

Ingredients

For the Casserole

2 cans (12–13 oz each) refrigerated cinnamon rolls, icing packets reserved
4 large eggs
1 cup heavy cream (or whole milk for a lighter texture)
1/3 cup maple syrup or pancake syrup
2 teaspoons vanilla extract
1 teaspoon ground cinnamon
2 tablespoons melted butter

Optional Toppings

Cinnamon sugar
Chopped pecans
Fresh berries
Powdered sugar drizzle

Instructions

Preheat the oven to 350°F. Lightly grease a 9×13 baking dish.
Cut the cinnamon rolls: Open both cans and cut each roll into quarters. Spread the pieces evenly in the baking dish.
Mix the custard: In a bowl, whisk together the eggs, heavy cream, maple syrup, vanilla, and cinnamon until fully combined.
Pour over the rolls: Slowly pour the mixture over the cinnamon roll pieces. Gently press them down to help them absorb the custard.
Add butter: Drizzle the melted butter over the top.
Bake: Bake for 28–32 minutes or until the center is set and the top is lightly golden.
Add icing: Warm the icing packets for a few seconds, then drizzle over the warm casserole. Add optional toppings if desired.
