Thanks so much for clarifying.
I'm using tesco Irish porridge oats which for 25g seems to be 4.5 syns so I did my sums last night and it's 2 muffins = 1 hexB after that they are 2.7 syns. I used 30g oats per 2 muffins. I haven't gone over my syn allowance - phew!! But at least now I know before I went overboard! Thanks again for letting us all know that they aren't syn free. Still totally worth 2.7 syns - even without fruit in them they're yummy!
