ah! but on THIS side of the pond, flapjacks will flap! (picture a thick crepe - very thick sometimes - up to 1/2 inch - but the good ones are light and fluffy.)

Your "flapjacks" sound like it's break or crumble. actually - the closest thing I can think of to what you are describing are "rice crispie treats" - which are made of puffed rice, butter or margerine and some kind of sugar - in most cases, melted marshmallows.

"down south" in the US you can get "golden syrup" I am told is very like Lyle's - tho' another brand. sorghum syrup.
