Butter the baking tray.
Melt the butter, syrup and both sugars in the saucepan. Do not allow them to bubble. Mix in the oats and the cocoa.
Use a fork to press the mixture into the baking tray and bake for 18-20 minutes. The flapjack needs to cook to the centre but you don't want them to bubble, otherwise they will be too toffee-like. They should stay moist.
Remove from the oven and leave to cool for about 20 minutes before slicing up. Leave to cool completely before removing from the tray.
Hint: these flapjacks are delicious with 2 tablespoons of dessicated coconut, or a handful of sultanas added with the oats. Equally tasty is 1 tablespoon of sesame seeds, but you will also need a handful of extra oats because the seeds will make the flapjacks oily.
