magical flapjack

I am with my family. My dad is telling me and my brothers about this
special irish food made out of oats. It is like a cake, very
nutritious, and it has chocolate on top. It looks like flapjack, but
tastes more like cake. It is crumbly. I really want to try some, so he
gives a small bit for me and my brothers to taste. Although it is only
small it fills us up so much that we can't finish eating it. It is so
delicious. We are in ireland while we eat it.
