John Lewis restaurants oaty biscuits - any ideas how to make them

[mylittlemonsters]

If you have been to a JL restaurant and had the oaty biscuits you'll know why I am obsessed with getting a recipe.

I'll settle for any decent crunchy oaty biscuit

There is a nice recipe in The Dinner Lady. Very easy & they look good too, will post the recipe if you haven't got the book?
