Preheat your oven to 175°C/347°F and line a baking sheet with parchment or a silicone mat.

Add the oil and whisk again.
Add the flour and stir until a homogeneous dough forms.
Form 40-50g balls depending on how big you like your cookies. The ones pictured are 50g. Roll them in sugar and place them on your baking sheet, leaving room in between for spreading.

Let them cool for 3-5 minutes on the sheet then transfer to a wire rack to cool completely.
