Very Easy Oaty Biscuit Recipe

I'm not sure what's going on but just lately I've been craving food with crunch. It's not the flavour of things I've been thinking about but the texture. I'm sure this has some deep psychological reason but there seemed only one thing to do: bake some biscuits. I'm not talking about soft crumbly cookies or biscuits containing a buttercream centre but an old-fashioned, honest-to-goodness crunchy biscuit.
