Preparation
1 Preheat the oven to 180˚C/160˚C fan/gas mark 4. Grease and line a 20 x 30cm baking tray.
2 Melt the butter, sugar and golden syrup together in a large, heavy-bottomed pan over a medium heat.
3 Once melted, add the vanilla extract, oats, grated apples and cinnamon. Mix until well combined.
4 Spread the flapjack mixture into the prepared pan and smooth the top with a spatula. Bake for 20-25 minutes until the bake is golden brown.
5 Allow to cool in the baking tin, then remove and cut into 12-15 bars. Store in a biscuit tin for up to a week.
