Chocolate Flapjack Recipe – BEST Chewy Flapjacks

Sharing is caring!

Just the BEST chocolate flapjack recipe – a super easy flapjack traybake that’s fun to make with the kids and oh so delicious to eat!

Chocolate Coated Chewy Flapjacks

We love flapjacks, they’re so easy to make and as they’re packed with wholesome rolled oats they’re a snack I’m happy to make for the kids to eat.

And… what’s better than flapjacks?

Well chocolate coated flapjacks that’s what! I do think an added layer of chocolate gives the flapjacks a touch of luxury.

I also like to add a little edible stardust for extra sparkly gorgeousness!

These are good to eat for breakfast with a coffee and I like to pretend like I’m being healthy…. ya know… because of the oats! Practically porridge… right???

Chocolate Flapjack Recipe Ingredients

You’ll just need a handful of store cupboard staples to make these delicious chocolate coated flapjacks.

ingredients for chocolate coated flapjacks - bowl of rolled oats, bowl of ready brek, bowl of butter, bowl of brown sugar, bowl of golden syrup and bowl of chocolate broken up into squares
  • 150g Butter
  • 50g Soft Brown Sugar
  • 2 tbs Golden Syrup
  • 220g Rolled Oats
  • 50g Ready Brek Instant Porridge
  • 100g Chocolate

How To Make Our Chocolate Flapjack Recipe

You will just love how simple this flapjack with chocolate recipe is to make and bake!

Step One – preheat the oven and line the baking tin

  • Preheat the oven to 180C
  • Grease and line 20cm square tin with butter and baking paper

Step Two – make up the chocolate flapjack recipe mixture

  • Add the butter, brown sugar and golden syrup to a large deep pan over a low heat on the hob. Stir everything together gently until it’s all melted.

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

Step Three – bake the flapjacks in the oven

  • Bake in the oven for 15 minutes. Then remove from the oven and leave on a wire rack – still in the tin to cool down.

Step Four – make the chocolate topping

  • Once the flapjacks are cooled melt the chocolate ready for topping. Do this by breaking the chocolate into chunks and putting it into a jug, stand the jug in a pan of boiling water and stir carefully until fully melted.

  • Pour the melted chocolate over the top of the cooled flapjacks and spread it out using the spoon so that the whole top of the flapjack traybake is covered.
  • I like to add a little sprinkling of edible glitter or stardust too just because is looks nice!

Step Five – Refrigerate the chocolate flapjack recipe

  • Put the flapjacks into the fridge for at least a couple of hours to set hard.

How To Make Chocolate Dipped Flapjacks

If you don’t want to top your flapjacks with chocolate then you can dip them instead.

Just cut the flapjacks, dip into the chocolate and leave in the fridge to set.

Can I Make Flapjacks With Ready Brek?

Well… not completely, you do need rolled oats for a true flapjack texture.

But adding Ready Brek into the flapjack mixture gives them a lovely chewy softer texture which is a little more cake-y and totally delicious!

How Long Can You Keep Flapjacks In The Fridge?

I store flapjacks 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!)
