If using canned baked cinnamon rolls, bake them according to the package instructions and let them cool slightly. Cut each cinnamon roll in half horizontally.
In a medium bowl, whisk together the eggs, milk, honey, vanilla extract, ground cinnamon, and a pinch of ground nutmeg until well combined.
Dip each cinnamon roll half into the custard mixture, ensuring both sides are well-coated. Let any excess custard drip off.
Heat a non-stick skillet or griddle over medium heat and lightly grease it with butter or cooking spray. Place the custard-coated cinnamon roll halves on the skillet. Cook for 2-3 minutes on each side, or until golden brown and crispy.
Serve the cinnamon roll French toast warm with your favorite toppings, like maple syrup, powdered sugar, fresh berries, or extra honey.
