In a bowl, add softened butter and icing sugar. Whisk it till it’s light, fluffy and pale in colour.
Then add flour and 3 tbsp milk and form it into a smooth dough.
Divide the dough into 2 equal halves. Add in cocoa powder and 1 tbsp milk into one half of the dough.
Divide both the doughs further into two halves and roll them into rectangular logs of equal length. (Approx. 3-4 inches)
Carefully brush some milk on one side and top of the vanilla log and place it next to the chocolate log using milk as a glue. Then, place the second vanilla log over the chocolate log and place the second chocolate log over the vanilla log. This should form a checkerboard pattern.
Carefully cling wrap the entire thing and freeze for 15-20 mins.
Preheat the oven at 180 degrees celsius for 10 mins.
Cut the cookie log with a sharp knife into equal thickness and lay them on a baking tray lined with parchment paper. This will yield around 10 cookies.
Bake the checkerboard cookies for 13-15 minutes. Let them cool completely before serving or storing.
