Start by making the vanilla dough. Cream together the butter and sugar until smooth. Add in the vanilla and mix. Gradually add in the flour, and mix until it forms a dough.

In another bowl, make the chocolate dough by once again creaming the butter and sugar. Add in the cocoa powder and combine. Gradually add the flour and mix.

NOTE: the chocolate dough may be crumbly and hardly coming together, if that's the case add in the 1 tbsp milk to easy things up. If your dough came together nicely, then there is no reason for the milk.

Cover both doughs with cling film and chill in he fridge for 15 mins.

Roll out the vanilla dough and cut it out into a 7x7 inch square.

Do the same thing with the chocolate dough.

Now cut each of the squares into 3 equal strips.

Stack one of the chocolate strip in between two vanilla dough strips.

And one vanilla in between to chocolate strips

Chill this for about 30 mins in the refrigerator

Preheat the oven to 180 C degrees

Line a large baking tray with parchment paper.

Leave to cool and enjoy!!!! :)
