Preheat the oven to 375 degrees F. Lightly spray an 11x7 baking dish with cooking spray.

Place the quartered cinnamon rolls in the bottom of the baking dish.

In a separate mixing bowl add the eggs, coffee creamer, vanilla extract, and allspice. Whisk together until well combined and the eggs are light and frothy.

Pour the egg mixture over the top of the cinnamon rolls. Use a spoon to gently combine the mixture in the baking dish, ensuring that all of the cinnamon rolls are coated with the egg mixture.

Place in the oven and bake at 375 degrees F for 35-40 minutes, or until the casserole is completely set in the middle.

While the casserole is baking, in a separate mixing bowl add both of the cream cheese frosting packages from the tubes of cinnamon rolls. Add the cream cheese and powdered sugar. Use a hand mixer to beat together until no lumps from the cream cheese remain.

Once the cinnamon rolls are done baking remove from the oven. Let sit 2-3 minutes and then spoon the cream cheese frosting over the top of them.

Serve warm and enjoy!
