Apple and oat muffins

I fancied a bit of kitchen therapy this afternoon and found this Apple and Oat Muffins recipe.  It ticked all the boxes as far as I am concerned: reasonably good/healthy(ish) ingredients; quick to make; and potentially super yummy.  I was surprised that it honestly only took 5 minutes to prepare (just whack it all in the mix master).  The bit that took the longest was scraping out the last of the Jalna Vanilla Yoghurt I was using (If you haven't eaten this before, put it on the shopping list).  I made smaller muffins so reduced the cooking time a little.

Only problem? Rejected by Master 6 due to the "skin" inside.  Next time, I'll grate the apple and mix it in with everything else.
