                                According to McDonald's official ingredient list for its Hot Fudge Topping in the U.S., the sauce contains a mix of sugar, water, nonfat milk, and hydrogenated palm kernel oil. Beyond these primary components, a variety of additives work to create its signature gooey texture, rich flavor, and long shelf life. This combination of standard and specialized ingredients differentiates the fast-food version from a simple homemade recipe.
