Preheat the oven to 190°C (170°C Fan, Gas Mark 5). Line a large baking tray with baking parchment.

Sift the flour and Baking Powder into a bowl then rub in the butter until well blended. Stir in the sugar and Chocolate Chunks.

Make a well in the centre then add the egg and Almond Extract. Mix to form a soft dough. Turn it out onto a lightly floured surface and form into a roll approx. 25cm (10inch) long. 

Transfer to the prepared baking tray and press gently to flatten to a depth of 2cm ( ¾ inch). Bake for about 20 minutes until lightly browned. Cool for 5 minutes, then carefully cut into 16 slices. Place back on the tray and bake for a further 5-8 minutes to dry and crisp without browning too much. Transfer to a wire rack to cool and enjoy!
