Preheat your oven to 400 degrees F (200 degrees C), grease a large baking tray well.

Put the flour, beer and 4 tbsp of the butter into a large bowl and mix well. Pour onto the greased pan and spread out with slightly damp hands into a (roughly) 12 by 9 inch rectangle.

Bake for 40 minutes until dark golden brown. Brush with the remaining butter. Cut into 12-16 sticks. Serve warm.
