Preheat the oven to 180C / 350F and line a baking tray with parchment paper.
In a mixing bowl, whisk sugar and melted butter.
Whisk in lemon juice and zest, eggs and vanilla extract until combined.
Stir in flour, baking soda and salt, then fold in the white chocolate.
Use a cookie scoop or tablespoon to scoop out the dough, then roll it into balls.
Place the cookies on the baking tray and slightly flatten them with your hand.
Bake for 10 minutes, then allow to cool completely before serving.
Notes
I like using a cookie scoop to scoop the dough to ensure all my cookies are the same size, which helps them bake evenly.Use a large measuring spoon if you don't have a cookie scoop.
