Preheat the oven to 375 degrees F (190 degrees C). Coat a 9×13-inch baking pan with melted butter.
Cut each cinnamon roll into 8 pieces and put into the prepared pan.
Mix eggs, milk, vanilla extract, maple extract, and cinnamon together in a bowl and pour over the rolls.
Bake in the preheated oven until golden and set, 23 to 30 minutes. Cover with packaged icing and serve.
