Step 1

Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Line two baking trays with baking or parchment paper.

Step 2

In a large mixing bowl, add butter and sugar. Beat with an electric mixer on medium speed until pale and creamy. Add vanilla and egg and beat again until combined.

Step 3

Sift in flour and baking soda. Add lemon juice and zest. Beat briefly until soft cookie dough forms.

Step 4

Roll cookie dough into 16 balls, approximately 1.5 tablespoons of dough each, and bake for approximately 12 minutes or until golden on the edges. Carefully transfer cookies to a wire rack to cool completely.

Step 5

To make the lemon glaze, sift the icing sugar into a mixing bowl. Add lemon juice, one tablespoon at a time, and mix together with a fork. Keep adding a tablespoon of lemon juice until you reach your desired consistency. You want the glaze to be smooth, but thin enough to drizzle.

Step 6

Drizzle glaze over cookies. Leave for 10-15 minutes to set.
