How to make Triple Chocolate Flapjacks
  1. Preheat the oven to 180°C, gas mark 4, line the baking tin (20x20 cm) with parchment paper and set aside.
  2. Pour the butter, Lyle's Golden Syrup, brown sugar and cocoa powder into a saucepan. Place over medium heat until everything is melted and whisk well until incorporated.
  3. Once melted, add the oats and chocolate into the mixing bowl, pour the butter mixture, and stir until the oats are fully coated.
  4. Transfer the flapjack mixture into the lined baking tin and press down with the back of the spoon or glass.
  5. Bake in the oven for 15 to 20 minutes, the flapjacks will slightly brown on the top. Leave the chocolate flapjacks to cool completely.
