Ingredients
 
 

  • 200 gram Light Brown sugar or demerara sugar.
  • 250 gram Butter
  • 5 tablespoon Golden Syrup or honey, agave syrup or maple syrup
  • 350 gram Oats instant or quick rolled oats for a soft texture jumbo rolled oats for a chewy texture

Instructions
 

  • Preheat oven to 180°c / 160°c fan gas 4 / 350 °F. Prepare the baking tin by lining it with baking parchment.
    We use a 8 x 8 inch square tin loose-bottomed cake tin, if using a longer tin they will come out thinner.
    Make sure parchment paper is longer than the tray to make it easier to remove later. See blog post for advice.

  • Remove from the oven, they will still be soft and greasy looking, don't worry this is normal they firm up as they cool. Do not be tempted to cook for longer!

  • Leave to cool still in the tin for at least 30 minutes. Once the tin has cooled down, place it in the fridge. This will cool the flapjack mixture quicker and make it set hard. The longer the better for neater cuts I suggest 2 hours+.
