Step One – Preheat the oven and line the baking tray

  • Preheat the oven to 180C / 350F / Gas Mark 4
  • Grease and line the 20cm cake tin with butter and baking paper – you really don’t need to be neat – just grease and lay the paper in so that it goes up the sides to the top, don’t worry if it’s hanging over, wrinkled or creased.

Step Two – Mix together the flapjack ingredients

  • Add the butter, brown sugar and golden syrup to a large deep saucepan over a low heat on the hob. Stir everything together gently with a wooden spoon as it melts in the pan. 
  • Next add the rolled oats and instant porridge into the pan with the melted butter, syrup and sugar. Mix everything together well so that all the oats are entirely coated in the buttery syrup.

Step Three – Get the flap jack recipe ready to bake

  • Tip the buttery sticky flapjack mixture into the lined baking tin and pat it all down tightly into the tin with the back of spoon. 

Step Four – Bake the golden syrup flapjacks

  • Bake in the oven for 15 minutes. Then remove from the oven and place the tin onto a wire cooling rack and allow to cool completely.

Step Five – Cut the flapjacks

  • Lift the slab of flapjacks from the tray and place onto a chopping board then slice into 12 equal pieces.

Flapjack Recipe FAQs

What is a flapjack?

A flapjack is a baked oat bar made with rolled oats, golden syrup, brown sugar and butter. They’re made as a traybake, then cooled and sliced into bars.

How to make flapjacks with honey?

Just swap out the golden syrup in the recipe and replace with the same quantity of honey. Remember it will change the taste of your flapjacks as honey has a more distinct taste than golden syrup.

How can I make flapjacks healthy?

Well flapjacks do naturally contain a lot of sugar – both in the form of brown sugar and syrup or honey. They also contain butter. To make a healthier flapjack think more about adding extra nutrients and eating a smaller portion than cutting the sugar which will ruin the texture and taste.

Add in dried fruit – apricots are a great addition to flapjacks, they add a nice moist chewy texture and are rich in fibre, potassium, copper, vitamin E and a source of iron and B12!

You could also swap out some of the oats for chopped nuts which are a great source of omega 3 as well as a range of vitamins and minerals.

How to make soft flapjacks?

The secret to soft flapjacks is definitely using instant porridge oats mixed in with the regular rolled oats. They give the flapjack a more cake’y like texture – totally delicious!

Also worth noting that if your flapjacks are coming out hard then it’s probably best to reduce the cooking temperature a little and cook for less time.

How to make chocolate flapjacks?

You can make chocolate flapjacks by adding in some cocoa powder to the oats mixture and reducing the oats slightly so the mixture isn’t too dry.

Or you can drizzle or coat them in a layer of chocolate once they’ve cooked and cooled.

How to make chewy flapjacks?

To get that chewy texture – use our recipe with the added instant porridge oats. It’s a total game changer!

How to make vegan flapjacks?

To make vegan flapjacks just swap out the butter for a vegetable based spread.

How to make fruit flapjacks?

Give your flapjack recipe a fruity twist – by adding in dried fruits or fresh berries. You can also add in mashed banana to your oats mixture.

How long can you keep flapjacks in the fridge?

I store these tasty oat bars in an airtight container in the fridge – they’ll last for about 5 days (although it’s rare they’re not all eaten within a couple of days of making them!)
