A note on oats

After making this many batches of homemade flapjacks over the years, I noticed something about the oats I used. (No exaggeration – I can safely say the success of your baking lies in the type of oats you use!) Once I realised this, there was no going back for me.

💥 HERE IS THE SECRET 💥… I use half rolled oats and half jumbo oats.

Rolled oats are more likely to be used in porridge. They absorb moisture well and carry flavours. Jumbo oats tend to be bigger and crunchier, keep their shape more, and are more likely to be used for biscuits and cereal bars. Instant oats are more processed, are finer in texture and are mushier when cooked.

In summary:

🦴 You can use just rolled oats but the texture is chewy, without much crunch

🍂 You can use just jumbo oats but they will be very crunchy, a little dry, and to be honest? Not my favourite

🌟 HALF AND HALF (rolled and jumbo) are honestly the BEST combo – both crunchy and chewy – yum!

🚫 Instant oats (like Ready Brek) are a no-no for flapjack

How we came up with this recipe for Flapjacks

A traditional Flapjack recipe originated in Great Britain and is made from butter, golden syrup, sugar, oats (my recipe has a touch of salt too and a chocolate topping to give it an edge).

Other recipes that involved using only one kind of oat, as mentioned above, just didn’t work for me. I know how I like my flapjack texture and overly one way or the other isn’t it!

Which is why the half and half method works so well.

Of course, there are a number of variations of flapjack recipes, such as peanut butter flapjacks, honey flapjacks, fruity flapjacks and banana flapjacks. But for me, nothing can top Golden Syrup flapjacks.

To make the best homemade flapjacks, simply melt and mix your ingredients together and bake in a square tin until golden brown, then slice them into squares once everything is cool. The melted chocolate is optional, but I’d highly recommend drizzling it over the flapjacks at the end.

This recipe will forever remind me of coming home from school and raiding the cake tin expectantly (and there is no hunger like that 3:30pm after-school hunger, is there?) Now it’s time for you to make your own memories. Hope you love it!

Flapjack Recipe Ingredients

• Butter – Unsalted or salted is fine. If you use salted, reduce the salt in the recipe to ½ tsp
• Golden Syrup
• Sugar – Soft light brown sugar
• Oats – I use a mixture of jumbo whole oats and rolled oats for a good consistency of both light/crumbly and dense at the same time
• Salt – You can leave this out for small children but it does bring out the flavour and add something
• Milk chocolate – Melted to drizzle (any kind). I use this kind for baking.

How to make Flapjacks

1. Preheat your oven, line your baking tray and then add your butter, sugar and golden syrup in a large pan.

2. Heat gently, then once the sugar has dissolved, remove from the heat and stir in the oats and salt.

3. Put your mixture into your baking tin and pat down flat with a spoon. Bake for 20 minutes until golden brown.

4. Leave to cool well before slicing and drizzling over the melted chocolate.

Substitutions

• Golden syrup – This gives the lovely sticky texture. You can replace it with honey if you prefer but it can be more unpredictable as honey is a natural product where the consistency varies. The flavour can also be quite strong.
  
• Brown sugar – Soft light brown sugar gives a good flavour but caster sugar will work too.
