Oat and Sunflower Squares

This week Adam and Tom went to see some of our neighbours who are advising Tom on building a computer. It's Tom's 17th birthday next week (no idea what cake I am going to bake), and he has been saving up to buy a custom made desk top PC. This is not my field of expertise, but I thought our neighbours would appreciate these oat and sunflower squares.
They are rather like flapjacks but only have a small amount of butter and syrup, so are more healthy. The sunflower seeds give it a nice crunch, however I think they could do with a little more syrup to bind the mix together. The ones in the picture were the best looking ones, and we did end up with quite a big bowl of unstuck bits - nice for snacking on!
The taste was good and I would probably rate them about 7.5, maybe more if they had extra syrup. Our neighbours, however thought that they were really delicious, and asked for the recipe, so that was great!
Oh, and I should add that I did not use jumbo oats as the recipe suggested, but ordinary ones - maybe they would have held together with larger oats, who knows?!
