I make some in my thermomix but you could do in a food processor.
200g oat
20 dates
4 tbs coconut oil
Dash vanilla
Choc chip or dried fruit if you wanted...

Process oats till fine, add coconut oil, dates and vanilla, process (looks like wet bread crumbs)
Stir through dried fruit etc...roll into ball.

The coconut oil binds them, so they will go hard in fridge etc..but are fine left out as long as its not too hot
