Honey Oat Slice

Not too long ago I posted a link to a recipe for Honey Oat Slice, only I accidentally sent you all to the wrong place.  So here it is again, a super yummy slice recipe that keeps a long time and packs great in a lunch box.  Just a few tips, it does seem to make a large mix, but it really does all go into one slice tin.  Just make sure have lined up a little past the sides of the tin if you use shallow tins like me.  And 300g of butter does seem like a ridiculous amount, but I promise it works.
