Chocolate pudding is a smooth, creamy dessert made by cooking milk or cream with sugar and cocoa powder or chocolate, thickened with a starch such as cornstarch or with eggs, then chilled to set. It is distinct from chocolate mousse, which is aerated with whipped cream or egg whites rather than thickened with starch, giving mousse a lighter texture. It is commonly topped with whipped cream or fresh berries, and is also used as a filling for pies, tarts, and parfaits.
