Hot fudge sauce is a rich, thick chocolate sauce that is typically served warm. It is made from ingredients like cocoa powder, sugar, butter, and cream, which are combined and heated until smooth. This decadent sauce is often used as a topping for desserts, especially ice cream. When poured over ice cream, hot fudge sauce melts slightly, creating a delicious contrast of temperatures. It can also be used in various desserts, such as brownies or sundaes, adding a sweet and chocolatey flavor. Hot fudge sauce is a popular treat in many ice cream shops and restaurants.
