Lemon and White Chocolate Flapjack Tips
- When zesting a lemon, don’t go into the white part (the pith) as it’s very bitter. You only want the outer yellow skin.
- Don’t boil the syrup mixture, just melt it then remove from the heat.
- Stir the oats in really well and make sure every grain is coated in the syrup. This will help it stick together better.
- Be careful not to over heat the chocolate in the microwave, it may cause it to bloom which doesn’t look great.
- Use a very sharp knife to cut your flapjack. Sounds simple but if it’s blunt at all, you won’t get clean lines and it will probably crumble all over the place!
- Keep a close eye on the flapjack towards the end of the cooking time. You don’t want to over bake as it will become dry – which is not the chewy flapjack that we all know and love!

(For a printer friendly version, see the recipe card at the end of this post)
Please note, this recipe includes both UK metric and US Cup measurements.
Ingredients
Here is what you will need to make 16 bars.
- 100g (1/2 Cup) Soft Light Brown Sugar
- 200g (3/4 Cup + 1/8 Cup) Unsalted Butter
- 3 tbsp Golden Syrup
- 1 Large Lemon (Zest and 2 tbsp Juice)
- Pinch of Salt
- 300g (3 x Cups) Rolled Oats
- 60g (2.1 oz) White Chocolate
- Zest of 1 x Additional Lemon, for Decoration (Optional)
Essential equipment
- 20cm (8″) Square Baking Tin
- 1 x Disposable Piping Bag or Sandwich Bag
Instructions
Preheat your oven to 160°C/Fan 150°C/320ºF and grease and line your baking tin with baking paper.
In a medium saucepan, melt together the brown sugar, butter, golden syrup, lemon zest, lemon juice and salt over a medium heat. Stir until smooth.


Weigh out the oats into a large bowl then pour over the melted syrup. Give it a really good mix to ensure all the oats are covered.


Now tip the mixture into your prepared tin and press it down firmly and evenly with the back of a spoon or a spatula.

Pop into the preheated oven and bake for 35-40 minutes until a deep golden colour on top.

Allow to cool completely in the tin before removing and slicing into 16 pieces. (A 4 x 4 grid.)
Decoration instructions
Then place a cooling rack over a sheet of newspaper and spread the flapjacks out evenly.
Break the white chocolate into your disposable piping bag or a sandwich bag & heat in the microwave in 10 second intervals. Give it a good ‘squish’ between each blast until it’s melted and smooth.
Then snip the end and pipe zigzags over each flapjack.

If you’re feeling fancy, while the chocolate is still melted and warm, grate a little lemon zest over the top of each bar. If the chocolate is still wet, it should stick.

Store in an airtight container at room temperature and consume within 5 days.

You can’t tell me you’re not tempted by these?! Look at the delicious melty chocolate goodness! These are definitely worth a go. Even if you don’t bake regularly, I promise you good results. You will be surrounded by lots of yummy noises before you can say, “Where did they go??”
If you’re looking for a pure and simple traditional flapjack, this gloriously delicious UK flapjack recipe will be right up your street!
