Preheat the oven to 170C and line a baking tray with baking paper.

Combine the plain flour and baking powder in a bowl and use your hands to rub in the butter to form a roughly crumb. Add in the egg, vanilla, lemon zest and milk and bring together with your hands or a blunt knife until it all combines together. Carefully fold in the blueberries. Be quick, so that the blueberries don’t run turning the whole batter blue.

Tip out onto a floured bench and form into a rough 8inch circle. Cut into 8 wedges and then spread out on prepared baking tray. Bake in the oven for 10-12min until golden. Allow to cool slightly.

Meanwhile prepare the glaze. Combine the icing sugar and lemon juice in a bowl. When the scones have cooled slightly drizzle with the glaze.
