Flapjack recipe

Preheat the oven to 180°C/160° Fan, 350°F, Gas 4 while you combine the butter and Lyle's Golden Syrup in a large non-stick saucepan. Heat gently until melted, then remove from the heat and stir in the oats and salt.

Chewy, classic, and packed full of healthy wholegrain oats, flapjacks are a long-standing family favourite. What’s more, these scrumptious snacks are notoriously simple to make and suit every occasion – from parties and gatherings, to low key evenings in front of the television. Flapjacks are baked bars that are made of just four ingredients: butter, golden syrup, rolled porridge oats and a pinch of salt. 

Enriching your flapjack recipe with Lyle’s Golden Syrup is the best way to achieve that irresistible melt-in-the-mouth texture and sweetly caramelised flavour, loved by generations.

This can happen if you overcook or undercook your flapjacks. When you overcook a flapjack, the golden syrup dries out and it becomes crumbly. An undercooked flapjack will have a raw doughy texture that doesn’t hold its shape. Be sure you are cooking your flapjacks for 25 minutes on 180°C/160° Fan, 350°F, Gas 4 for the perfect chewy bake! 

If you’re feeling adventurous, try adding some extra ingredients to your flapjack mix. Some popular additional extras often include berries, chocolate, caramel, raisins, and nuts. The rest of the flapjack recipe stays the same, but you get to indulge in an extra special twist!

While flapjacks are without a doubt a delicious sweet treat, they do contain butter, sugar and syrup. For that reason, we wouldn't describe them as 'healthy' but more as a tasty snack to be enjoyed in moderation.

Be careful not to cut them straight after they come out of the oven as they might be too hot and burn you. You also don't want to let them cool down completely before cutting them as they'll be too hard. You should always cut flapjacks while they're still warm so you can easily slice through them and create even, equal slices.

We'll be very surprised if there are any leftovers from your delicious homemade flapjacks, but if there somehow are some that survive, they'll keep for about ten days in an airtight container.
