Calories 417kcal


  • 4 medium apples about 400g
  • 150 g raisins
  • 250 g unsalted butter
  • 4 tbsp golden syrup
  • 100 g light brown muscovado sugar
  • 500 g oats
  • 1 tsp cinnamon


  • Pre-heat the over to 190ºC/170ºC fan.
  • Line a baking tray with greaseproof paper (My tin is 20cm x 26cm). 
  • Peel and chop the apples (4 medium)
  • Put the apple and raisins (150g) in a small pan and cook on a low heat until the fruit is soft (around 5 minutes), stirring occasionally to prevent it burning.
  • Meanwhile put the butter (250g), golden syrup (4 tbsp) and light brown muscovado sugar (100g) into a large pan and cook on a low heat until the butter has melted, stirring occasionally.
  • Once the butter has melted, remove from the heat and add the oats (500g) and cinnamon (1 tsp) and stir until fully combined.
  • Once the apple and raisins are soft, mash them until they are mushy.
  • Place half of the oat mixture into the pre-lined tray and push down firmly to form an even layer - you must push down firmly to ensure that the flapjack doesn't fall apart when you remove it from the tin later.
  • Add the apple and raisins to the tin and spread to form an even layer.
  • Add the remaining oat mixture and press firmly into an even layer.
  • Place in the oven and cook for 20 minutes until they are golden in colour and slightly darker around the edges.
  • When the flapjacks are cooked, remove from the oven and leave to cool in the tin for 10 minutes.
  • After 10 minutes, transfer to a wire rack to cool thoroughly.
  • Serve.
