Gurs bil-zaatar (za'atar biscuits)

Instructions

1. Preheat the oven to 180 °C (160 °C fan).
2. In a bowl, beat the softened butter with the sugar until smooth and creamy.
3. Add the egg and vanilla, and mix well.
4. Stir in the flour, baking powder, salt and za'atar, then add the milk little by little until you have a soft dough.
5. Shape small balls the size of a walnut and flatten them slightly on a tray lined with baking paper.
6. Bake for 12 to 15 minutes, until the edges are lightly golden.
7. Let cool on a rack before eating; the biscuits firm up as they cool.
