Our Flapjack Story

I’ve been making flapjacks ever since my lot were tiny tots and it is the recipe we return to whenever we need a bit of sweet comfort food in our lives.

The comfort of familiarity is hard to beat and when my children are feeling a bit put upon, when the day at school has just been a bit much it it this traditional flapjack that they ask for – who am I to refuse?

Making Flapjack Vegan

I first shared this recipe back in the very early days of Thinly Spread when we were all vegetarian and it was butter I turned to in my baking.

Now that most of us are vegans I’m gradually working my way through old recipes, reworking them without dairy produce and eggs, testing them carefully and updating them, especially family favourites like this one!

I am pleased to report that this vegan flapjack holds together just as well and tastes just as good without dairy butter, I didn’t have to adapt it at all, I simply added the same quantity of vegan margarine as I had of butter and it worked, which was very satisfying indeed!

The Best Chewy Flapjack Recipe!

I know that I am not the only the vegan whose only choice in a coffee shop has been a dusty sad and worthy flapjack and there really is no excuse.

Just look at that edge – glowing in the late afternoon autumnal sunshine – all chewy and delicious and not just a crumbly mouthful of disappointment!

The added handful of bran or cornflakes make them extra special, it gives them a bit of crunch and allows me to pretend that they are healthier than they are!

We add in dried fruit for a bit of extra oomph or drizzle them with chocolate but sometimes, at the end of a fractious day only the old recipes hit the spot; unadulterated, just as we remember them.

What is the Secret to Tasty, Chewy Flapjacks?

I’ve seen recipes which call for agave nectar or rice syrup in an attempt to drag the flapjack kicking and screaming into the healthy food arena but it’s not for me.

First up, those sugary substitutes may sound all fancy pants but they are just that, substitutes, they are not some new health elixir, they’re just sugars with another name.

The secret to a really good traditional flapjack is Golden Syrup in all its sticky, sunshiny glory. Flapjack is a treat, not a staple foodstuff, so pour yourself a cuppa. kick off your shoes and enjoy!

    We are flapjack lovers in our house too.

      Yummy recipe, I added a handfull of sultanas to it.


      • Chris Mosler on October 20, 2019 at 11:18 am

        It’s such a good one to adapt Marion, sultanas are a lovely addition! I sometimes chuck in chocolate chips, dried cherries are good and a bit of spice and some dried cranberries work really well at Christmas, I’m so glad you enjoyed it 🙂 Chris (Thinly Spread) x

    I’m a firm believer in nothing being completely banned! As long as they eat enough healthy food, mine are allowed whatever they like (within reason!) – we’re all addicted to crunch at the moment though – hummus and breadsticks is a favourite, or those naughty peanuts with a crispy coating! Those flapjacks look yummy.


    • Chris Mosler on July 18, 2011 at 3:34 pm

      Hear Hear! I also think if you get too hung up on the healthy food message it can swing them the other way and backfire. Mine eat a very healthy diet and I am totally relaxed about the snacks in between…within reason! It’s common sense! x


  3. Midlife Singlemum on July 18, 2011 at 3:36 pm

    Those flapjacks look worth trying – and I am not a baker. I’m saving the recipe now.


    • Chris Mosler on July 18, 2011 at 4:01 pm

      Hooray! 🙂 Let me know how you get on if you have a go at them!


  4. Red Ted Art on July 18, 2011 at 3:42 pm

    Oooh we have a “family” granola bar recipe too and LOVE it.. haven’t made any in ages, must make some more!


    • Chris Mosler on July 18, 2011 at 4:04 pm

      I make this frequently because it is SO easy and they love it! Great to have a handy stand by! x


  5. Suzanne on July 18, 2011 at 3:47 pm

    Another flapjack family here! My husband makes them with bags of supermarket own-brand cheap muesli, which works really well with the dried fruit. Also, he uses mashed banana to cut down on the sugar. Super yummy. Everything in moderation in our house.


    • Chris Mosler on July 18, 2011 at 4:08 pm

      Oooh, what a good idea! I make fruity flapjacks with fresh and dried fruit but I haven’t done it with muesli! I shall be experimenting! Thanks! 🙂


  6. Boatwife on July 18, 2011 at 7:09 pm

    I love flapjack! I am not so strict that I wouldn’t allow it, but just don’t have time to make it. After nursery snacks for my tiny ones are often yoghurt or cheese. Sometimes fruit.


    • Dave on May 9, 2019 at 8:13 pm

      Took about an hour with my 3 kids, they enjoyed doing it as well,


  7. Lisa on July 19, 2011 at 8:49 pm
