  • Line a square baking tin (mine is 20 cm in diameter) with non-stick paper, and spread the mixture, pressing down well for an even bake.

Notes

  • The ration butter to sugar and golden syrup is crucial in order to achieve a nice chewy texture that does not come apart - too little butter, and they will be too crumbly, not enough sugar, and they will be too tough.
  • Do make sure to slice the flapjacks as soon as they come out of the oven, otherwise it is impossible to do it once they cool down completely and harden.
  • The squares can be stored into an airtight container, and they can stay fresh for many days - best served with a nice cuppa!
