Traditional "alfajores" in Argentina, Peru, Uruguay and Venezuela consist of two round, sweet biscuits made of wheat flour or corn starch joined together with dulce de leche (known as "manjar blanco" in Peru and as "arequipe" in Venezuela), and optionally coated with powdered sugar. More modern "industrial" varieties in Chile, Uruguay and Argentina, are coated with dark or white chocolate (many "alfajores" are sold in "black" and "white" versions), or simply covered with powdered sugar. These are also known as a "Chilean Oreo". One variation is called ""alfajor de nieve"" (snow alfajor) and has a white coating consisting of a mixture of egg whites and sugar. Most "alfajores" come packaged in aluminium foil. Alfajores are made in various diameters and are consumed as snacks.
