Mont Blanc is currently available in nine different flavors. Classique, White Chocolate, new Creamy Dark chocolate, Raspberry, Hazelnut, Mocha, Cinnamon, Amaretto, and a Sugar-Free classique sweetened with Nutrasweet. Mont Blanc is packed in single serving packets, a 5 serving MiniTins and the original 15 serving large tins. You could, but you are better off using a high-quality cocoa powder. Since Mont Blanc is a cocoa mix, it contains milk and cream powder and sugar to make a drink by adding hot water.
Most recipes call for plain cocoa powder or chocolate.
A recipe I have says to use dutch cocoa powder. Dutching is a process that adds an alkali to cocoa powder to help mellow the taste. Dutching simply enhances the flavor and color of the cocoa powder.
