- Mix the butter and the brown sugar together with a wooden spoon or a mixer until it appears light in texture and pale in colour.
- Add in the flour and stir in until it is roughly mixed to form a dough.
- Press the dough thinly and evenly across an 8 inch square baking tin.
- With a knife, line the surface of the dough into 6 rows and 4 columns for cutting later, then pierce the dough with a fork across the surface to give an even and textured appearance.
- Preheat the oven to 160C, 325F or Gas Mark 3.
- Cover the dough and place in the refrigerator for half an hour before baking for 25 minutes or until the dough is a light brown colour.
- Once removed from the oven and still in the baking tin, cut the shortbread using the drawn lines and let cool before placing into an airtight container.
