Crispy Chocolate Biscuit

Preheat oven to 170°C.

Place Dr. Oetker Nona Corn Starch, Custard Flour, Plain Flour, Cocoa Powder and icing sugar in a mixing bowl. Stir well.

Add in egg yolks and stir evenly until the mixture formed looks like "breadcrumbs".

Gradually add in butter and knead until a soft dough is formed.

Cut the cookies as your desire shapes and decorate with hundreds & thousands.
