Ingredients
 
 

  • 400 g Porridge Oats, Quick Oats
  • 200 g Unsalted Butter
  • 200 g Golden Syrup
  • 200 g Light Brown Soft Sugar
  • 100 g Milk Chocolate

Instructions

  • Preheat the oven to 150C
  • Place the butter, sugar and golden syrup in a pan and melt together over a low heat until the sugar has dissolved completely.
  • Pour in the oats and mix them together well. Ensure all the oats are covered in the butter mixture.
  • Line and grease a 20x25cm baking tin with parchment paper. Leave the paper to hang over the top of the tin to create an easy way to lift the flapjacks from the tin later.
  • Tip the mixture into the lined tin and, using the back of a spoon or a spatula, press it down firmly and evenly.
  • Bake in the oven for 30 minutes.
  • Remove the tin from the oven, the mixture will still appear slightly soft.
  • Leave the mixture in the tin to cool and harden.
  • Once the flapjacks have cooled to at least room temperature, melt the chocolate over a low heat or in 10 second increments in the microwave.
  • Pour the chocolate over the top in an even layer and allow to set almost completely.
  • When the chocolate has hardened but isn't completely set, use the parchment paper to lift the mixture out of the tin and place it on a chopping board.
  • Using a very sharp knife, slice the flapjacks to the desired size. These can be bite-size pieces, square bars, or thin slices. Whatever you prefer.

Recipe Notes

 
  • Using porridge oats gives the best results. However, you can also use rolled oats. Jumbo oats create a more crumbly texture and will fall apart more easily.
  • Take your time to press the mixture down firmly in the tin, this will help to keep it all together. 
  • Don't add extra baking time when you see that the mixture is still soft. It will harden as it cools.
  • Slicing the flapjacks before the chocolate sets completely will help to give you uniform slices and prevent the chocolate layer from cracking and breaking.
