How to make:

1. Beat the butter, salt, and icing sugar until light and creamy. Add the egg yolk and beat until well combined.
2. Sift together the wheat flour, cocoa powder, milk powder, cornstarch, and baking powder. Add to the butter mixture along with the ground almonds. Mix until well combined.
3. Take a small amount of dough and shape it into a ball. Roll it in the chopped sliced almonds. Place the balls onto a baking tray lightly greased with margarine.
4. Bake in a preheated oven at 150°C (lower heat only) for about 30 minutes, or until baked through.
5. Once cooled, decorate with drizzles of melted dark and white chocolate.
