Mix the butter, caster and icing sugar, egg yolks and vanilla with a wooden spoon until creamy, then mix in the flour in 2 batches. Roll out to a 20 x 30cm rectangle on a sheet of baking parchment. Mix the demerara sugar with the cinnamon, sprinkle all over the dough, then gently roll over a rolling pin again to press the sugar in a little. Roll up from one of the 20cm sides using the parchment to help, wrap in the parchment and chill for 30 mins, or up to a day.
Heat oven to 200C/180C fan/gas 6. Thinly slice into about 20 biscuits, scatter with a pinch more sugar, then bake on baking sheets for 10-12 mins until golden.
