British Flapjacks

Spread the love

Have you ever eaten British flapjacks? I don’t mean the American flapjacks which are a sort of pancake but the British version which is a sweet treat made with oat flakes and syrup.

No? Then you are in for a treat!

This is the easiest recipe to make.

Great if you want something simple to make with the kids or as a quick surprise treat for when they get home from school.

I have just made these this morning as per my daughter’s request.

They were having a ‘high tea’ at school this afternoon and her friends had asked if she could bring these in again (she had made these herself for her class when she did her ‘show and tell’ presentation about England).

After all, no food is more British than Flapjacks!

Another reason I like this recipe is that it only has a few ingredients and is really cheap to make – what more can I say?

You should really try them!

I normally work with grams but I have also converted them to cups for those of you that would rather use this method of measurement.

Flapjack Ingredients

How to make flapjacks

*for gluten-free flapjacks just replace the rolled oats with a gluten-free version*

(please always double-check your ingredients – I believe Lyles golden syrup is gluten-free but I would advise you to personally check labels just to be sure)

  • 250g (or 2 3/4 cups) – Oat flakes
  • 125g  (or 3/4 cup) – Brown Sugar
  • 125g  (or 1/2 cup) Unsalted Butter
  • 3 Tablespoons (or 1/4 cup) – Golden Syrup


Chocolate Chips
Anything else you can think of 🙂

Cooking With A Kitchen Aid Mixer

I use my mixer (with the dough hook attachment) for this just to save a bit of time but it can just as easily be done by hand just using a wooden spoon to mix it all together.

Directions To Make British Flapjacks

In process images of how to make British flapjack.
  • Turn the oven on to warm up – 180°C
  • Grease a 30cm x 15cm tin and line it with baking paper (I use a reusable non-stick Teflon sheet).
  • Cut the butter into small cubes and microwave for 10-15 seconds (not too much, just to soften slightly).
  • Put the oats, sugar, butter, and syrup together in a bowl & mix well until everything is combined.
  • Now add any extras (chocolate chips, raisins, etc).
  • When everything is well-mixed tip it into the lined baking tin and spread the mixture out. With the back of a spoon pack it down as tightly as you can, making sure you also push it right into the corners.
  • Put into the middle of a preheated oven for 18-20 minutes.
  • When golden brown, remove from the oven and set aside to cool (mine looks quite dark in the photo because I have used a very dark brown sugar).
  • After about 5-10 minutes, whilst the flapjack is still soft cut into portions (normally this would be cut into 12 portions but I prefer to cut mine into 24 smaller pieces – which is just right for little fingers!)
  • Allow the flapjack to completely cool before eating (if you can wait that long!).
  • This time I also drizzled melted chocolate on the top for presentation purposes (I don’t always do this but I wanted them to look nice for the high tea).  This was really easy to do – just pop a little bit of chocolate into the corner of a plastic bag, microwave for 15-30 seconds (until it’s just melted), then snip a tiny hole in the corner and drizzle it over your flapjack.
