Chocolate Cake Day takes place on January 27, 2025. This day celebrates a sweet cake, all made of chocolate. Usually such a cake is flavored with melted chocolate or cocoa powder. Of course, it can contain other ingredients, too. Chocolate Cake Day, for example, can be celebrated baking a chocolate cake, which also contains vanilla cream or fudge. In 1764, Dr. James Baker discovered how to make chocolate by grinding cocoa beans between two massive circular millstones. Starting then, recipes for chocolate cakes spread all over the world, making this cake a very popular cake.
