Place butter, sugar, treacle, bicarb, spices and salt in a mixer and combine well, scraping sides as necessary. Add milk and mix until combined. Add flour and mix until a smooth dough has formed. Divide in two and flatten, wrap in plastic wrap and rest in the fridge for at least an hour. Preheat oven to 170C. Roll out dough on a lightly floured bench to 5mm thickness and cut into desired shapes. Place on a lightly greased baking tray and bake for 8-10 minutes or until cooked through and just starting to turn golden. Cool on a wire rack and store in an airtight container.
