A chocolate cake is a cake made with chocolate or cocoa. The ingredients are put into a bowl and mixed together; then the mixed ingredients are put into a cake tin and put in an oven until it is fully cooked. Then the cake is taken out of the oven and placed on a cooling stand. If the cake maker wants to, they can ice the cake, when it has cooled down, by spreading thick icing on it.
Chocolate cakes are sold in shops as well as made at home. They are a sweet food and should not be eaten all the time, which would be unhealthy.
There are many different types of chocolate cake, depending on the recipe and different types of chocolate used. Different countries have different recipes for chocolate cakes. In France, gâteau au chocolate is popular. In Germany, Sachertorte is popular.
