Pre-heat oven to 180 degrees celcius. Cover a baking tray with parchment paper.
Sift flour into a large bowl. Add salt, pepper and baking powder. Mix.
Add in chilled butter. Mix with your fingertips to form fine breadcrumbs.
Add in grated cheddar and continue mixing with your fingertips.
Gradually add in thee milk to form a soft dough. Start with a metal spoon then use your fingertips once it starts to stick together. Form the dough into a ball.
On a lightly floured surface, roll the dough to a thickness of approximately 2cm.
Cut out rough circles using a metal knife. To make them more even (and less 'rustic') you can use a round cutter.
Place the circles onto a baking tray and brush with milk.
Top with extra cheddar.
Bake for 12-15 minutes at 180 degrees.
Cool for around 10 minutes on a wire rack. Best served fresh.
