Flapjack recipe

Follow the 3 simple steps of our flapjack recipe for the ultimate Lyle’s Golden Syrup flapjack:

Step 1

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.

Step 2

Spoon the flapjack mixture into a 20cm (8”) shallow loose-bottomed square baking tin, greased and lined with baking paper. Level and press firmly with a palette knife to smooth. Bake on the middle shelf for 25 minutes, until gorgeously golden brown on top.

Pro tip

Lining the baking tin with parchment paper makes it easy to remove the flapjacks. Once they have cooled in the tin you can slide the whole flapjack on its paper onto a board to cut into pieces.

Step 3

Remove and leave to cool in the tin for 30 minutes. Then lift out of the tin to cool completely on a wire rack. Once cooled, cut into squares that can be picked up and enjoyed by your family and friends.

Pro tip

Flapjacks can be frozen but remember that if they contain moist fruit such as apples or blueberries, they might soften on thawing.

Frequently asked questions about flapjacks 

Why do my homemade flapjacks fall apart?

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! 

What can I add to flapjacks?

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!
