No, because the ingredients can still be separated, so it's a physical change. Once you bake it however, it's a chemical change.
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
