Preheat oven to 180°C.
In a bowl cream together butter, sugar and lemon zest.
Add the milk and lemon juice and beat until fluffy.
Add the flour and mix to form a sot dough.
Now take small lemon sized balls and place them on a greased baking tray. With the flat side of a tumbler, press the ball to make it flat. I have used a peda press to get the design on top.
Bake the cookies for 10-15 minutes or until golden brown.
Transfer to wire rack and allow it to cool completely.
Meanwhile prepare the icing.
In a bowl beat together butter, lemon zest and lemon juice.
Add icing sugar one cup at a time and keep on mixing until you get the correct spreadable consistency.
Once the cookies are cool, apply the icing on one cookie and place another cookie on top.
Dust the cookies with icing sugar.
Serve with a cup of tea.
