An easy recipe for Scottish air fryer golden syrup flapjacks. A chewy oat bar that's super easy to make.
🧾 The history of Scottish flapjacks
Flapjacks are a traditional Scottish recipe.
You could say they were a bit of a happy accident. A very long time ago (oats were introduced to Scotland in 600 AD), crofts would have something known as a porridge drawer.
In the morning a big batch of porridge was made in a pot over the fire. and served hot in a bowl for breakfast.
Leftover porridge was poured into the porridge drawer where it would cool and set before it was cut into slabs.
And that's how flapjacks were invented.

♨️ Air fryer flapjacks
I usually bake flapjacks in the oven, but now I have an air fryer, I want to cook everything in it.
If you've bought one too you'll know what I mean.
I have a Tower Air Fryer, one of the ones with shelves and luckily enough my brownie pan fits perfectly.
My brownie pan is a 20 cm (8 inch) square tin.
Air fryers come in different sizes so you may need to measure yours to find a pan that fits.
Once your flapjack mixture is in the pan it can go on the shelf or the base of your air fryer.
If your air fryer is one with a drawer, you might want to pop something under it to raise it off the base.
Of course, you could bake this in the oven if you don't have an air fryer, just keep an eye on it from 20 minutes onward.

🥘 Lining your pan
You can use a silicone or metal brownie tin for these oat bars.
Even though silicone is supposed to mean easy removal, I'd still line the pan.
I grease the brownie pan then lay a strip of non-stick baking paper across the tin, with some excess over the edge which you can hold on to when lifting it out.
⭐ The best non-stick baking paper
I now buy double-sided non-stick parchment baking paper, which is non-stick on both sides.
On too many occasions I used the wrong side of normal baking paper and my baked goods would stick to the paper. So annoying!
I use ZeZaZu parchment sheets for baking (in case you are interested).
I buy them from Amazon as I couldn't find just what I was looking for elsewhere. They come in a cardboard packet of 100 unbleached sheets.
They are pre-cut into rectangular sheets which is super handy and fits my sheet pan perfectly.
Of course, there will be other brands available.
🔪 Should flapjacks be crisp or chewy
In my opinion, and the way we eat them here in Scotland is soft and chewy with maybe just a little crisp at the edges.
If they are thinner and crisp they are more of a cereal bar or oat bar.
These are known as oat bars elsewhere, but as we laid claim to them first in Scotland, they are definitely flapjacks.
To confuse things further in some parts of America flapjacks are what we call Scotch pancakes like these vegan banana pancakes.
📋 What you need to make golden syrup flapjacks
Here's what you need to make this energy-boosting Scottish oaty snack.
- Butter (vegan)- or dairy-free spread
- Golden syrup - to sweeten and bind
- Brown sugar - no one said these were low calorie
- Porridge oats - also known as rolled oats
- Salt - just a pinch
See a very simple recipe.
Not as simple as the original flapjack which was made with just oats, water and a pinch of salt (butter and sugar were a later addition), but just a few ingredients.
These oat bars are a great as a lunch box snack and kids love them.

The full recipe and method can be found in the recipe card at the bottom of this post after the step-by-step photos.
Here are a few tweaks you can make to the recipe.
- Maple syrup - You could use maple syrup or agave nectar instead of golden syrup
- Raisins- raisins, sultanas or cranberries make a good addition
- Walnuts - are also good in a flapjack
- Chocolate chips - who doesn't love a bit of chocolate
- Coconut - dessicated coconut for flavour
- Cinnamon - ground cinnamon or ginger add a nice warmth
- Banana - I sometimes add mashed banana to a flapjack and cut down on the sugar. Try these Banana, Coconut & Chocolate Chip Flapjacks.
- Grated carrot - yup I sometimes add grated carrot too. Try these Carrot, Banana & Chocolate Chip Flapjacks.

⏲️ How long will flapjacks keep
Flapjacks can be stored in a cake tin or an airtight container.
I usually line with baking paper, wrapping it over the top of the flapjacks.
They will happily keep for up to a week, less if your container isn't airtight.
They don't need to be kept in the fridge, but you can if you like.

Air Fryer Golden Syrup Flapjacks
- 250 g vegan butter or dairy-free spread
- 200 g golden syrup
- 50 g brown sugar
- 400 g porridge oats also known as rolled oats
- 1 pinch salt
- Grease and line a brownie pan. Mine is a 20 cm (8 inch) square pan, but you may need a smaller baking tin depending on your air fryer size.
- In a pan melt the vegan butter, golden syrup and brown sugar. Once melted set aside.
- Measure the oats and salt into a mixing bowl and mix.
- Pour the wet ingredients in and mix well until the oats are completely coated.
- Pour the flapjack mixture into the pan and press down firmly to make as even a layer as you can.
- Bake in your air fryer at 180c or 350 f for 20-25 minutes until golden.
- Remove from the air fryer and leave to cool in the pan.
- Once cool, you can carefully remove the block from the pan and cut into 16 bars or you could cut into 25 smaller bites.
- Your air fryer might not be big enough to hold a brownie pan, do measure first to see if one will fit, it not look for one or two smaller pans.
- My air fryer has shelves, if yours does not, then pop something underneath the pan, when you pop it in the drawer to raise it off the bottom.
- The flapjacks can be kept in a cake tin or airtight container for up to a week. I like to wrap them in baking paper.
