How to make
Sift the flour with a pinch of salt and a generous pinch of baking powder into a bowl.
Add one egg, one yolk, vanilla sugar, sugar and chopped cold butter.
Knead a soft butter biscuit dough.
Divide the dough into two equal parts. Add sifted cocoa to one and mix, until an even color is obtained.
Wrap both doughs in a piece of cling film and refrigerate them for 1 hour. Cut small balls from the cooled dough. Shape each one into a stick.
Make the sticks into a horseshoe shape and place the ends on top of each other.
Arrange the two tone biscuits on a baking tray lined with baking paper.
Bake for 8-10 minutes in a preheated oven.
Cool the two tone butter biscuits on a wire rack.
Enjoy!
