Weigh the butter, brown sugar and golden syrup into a pan. Heat slowly until the butter and golden syrup have melted and the sugar has dissolved.
Sift the flour into a large bowl.
Add the baking powder, ginger and cinnamon to the flour and mix.
Pour the melted butter/sugar/syrup mixture into the bowl with the dry ingredients and mix to form a smooth dough. Leave to cool slightly.
Roll out onto a lightly floured pastry board to a thickness of about 0.5cm.
Cut biscuit shapes using biscuit cutters and place on a non-stick baking parchment on a baking tray. Leave a minimum space of 2cm between each biscuit.
Chill the uncooked biscuits for around 30 minutes before baking.
