Preheat your oven to 375°F (190°C). Generously grease a 9x13 inch baking dish with butter or non-stick cooking spray to prevent sticking.
Open the cans of cinnamon rolls and cut each roll into quarters. Evenly distribute the quartered pieces in the greased baking dish, ensuring they’re spread out for even cooking.
In a large mixing bowl, crack the eggs and whisk them together until well beaten. Add milk, heavy cream, vanilla extract, ground cinnamon, nutmeg, and maple syrup to the bowl. Whisk until the mixture is smooth and fully combined.
Carefully pour the egg mixture over the cinnamon roll pieces, making sure every piece is soaked. Gently press down on any rolls that remain above the liquid to immerse them.
If desired, sprinkle the chopped pecans evenly over the top of the casserole for added texture and flavor.
Place the baking dish in the preheated oven and bake for 25-30 minutes. The casserole should be puffed up and golden brown; check for doneness by inserting a toothpick into the center—it should come out clean.
Once done, remove the casserole from the oven and let it cool for about 5 minutes to make slicing easier.
Drizzle the icing from the cinnamon roll cans generously over the top of the warm casserole. For a delightful presentation, dust with powdered sugar just before serving.
Notes
Serve warm with a sprinkle of powdered sugar and a drizzle of maple syrup.
