What is "frosting"?

Frosting, also known as icing, is a sweet and creamy topping or filling used to decorate and flavor cakes, cupcakes, cookies, and other desserts. It is typically made from ingredients such as butter, powdered sugar, milk or cream, and flavorings such as vanilla extract or cocoa powder. Frosting can vary in texture and flavor, ranging from light and fluffy to thick and creamy, and from vanilla to chocolate or fruit-flavored. It is spread or piped onto baked goods to add sweetness, moisture, and decorative appeal, often embellished with sprinkles, chocolate chips, or other decorations.
