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!

        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.

      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

    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.

      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! 🙂

    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.

Easy Vegan Flapjack Recipe With Secret Crunch | Thinly Spread (2024)

FAQs

Why are my flapjacks too crunchy? ›

Over mixing: Over mixing the ingredients can cause the gluten in the flour to become overdeveloped, which can make the flapjacks tough and crumbly. Over cooking: If you cook your flapjacks for too long, they may become dry and fall apart.

How do you make flapjacks not crumble? ›

When you overcook a flapjack, the golden syrup dries out and it becomes crumbly. An undercooked flapjack will have a raw doughy texture that doesn't hold its shape. Be sure you are cooking your flapjacks for 25 minutes on 180°C/160° Fan, 350°F, Gas 4 for the perfect chewy bake!

Why hasn't my flapjacks set? ›

cold cutting might well be the solution! I also find mine hold together better if when I'm melting the butter sugar and syrup bit, I let it bubble for a minute. These are good tips! I've had problems with flapjacks being a pile of (delicious) crumbs, and I cant believe it's the recipe as Nigella is usually so reliable!

Why do my flapjacks break up? ›

Too crumbly - oats too large or too many additions if you're adding nuts and fruit etc, use the small cheap oats, or grind them with a pestle and mortar. Also flatten the mixture down well in the tin. Rock hard! - baked too long, when the flapjacks come out of the oven they should still be bubbling a little.

What happens if you put too much syrup in flapjacks? ›

For me, too much golden syrup makes them hard to bite through and dunking is simply not an option with flapjacks. Golden syrup can also make flapjacks sickly sweet. Cooking times and oven temperature are important.

What to do with failed flapjack? ›

Use as a crumble topping for fruit, yogurt, ice cream. Or sundae - layers of fruit, yogurt and crumble. Or custard.

Should you cut flapjacks hot or cold? ›

Do you cut flapjacks when they're hot or cold? Mary Berry suggests allowing the flapjacks to cool slightly before removing them from the tin and cutting them. I personally find it a bit easier to wait until they have cooled completely and hardened before removing them.

Why are flapjacks unhealthy? ›

Flapjacks contain high levels of sugar, syrup and butter, meaning it shouldn't be mistaken as a food that has many health benefits but rather as a delicious treat to have in moderation.

How do you know when flapjack is ready? ›

Press evenly into the baking tray and bake on a high shelf in the oven for 15 minutes. The flapjack will still feel soft. Leave to cool in the tray for 5 minutes and then lift the baking paper up and out of the tray to cool completely. Cut into bars and enjoy!

How do you make flapjacks hold together? ›

4 Spread the mixture out, pressing it out evenly with the back of the spoon. 5 Bake for 25 minutes until golden. After five minutes cooling, press the flapjacks with something heavy and flat (this compresses them and stops them falling apart).

How do you bind flapjacks? ›

Butter and syrup are the binding agents that help hold flapjacks together, meaning you end up with deliciously chewy, buttery slices.

Why is my flapjack not chewy? ›

Adding flour helps make them chewy and soft. If you missed the flour, that could be the reason. If they do turn hard, leave them in the open air for a few hours to help soften them a little. TIP: You can also store them with a slice of bread to keep them soft, or to help soften hard oat bars.

Can flapjack go out of date? ›

On every product page, you will find the shelf-life listed for each flapjack. The general rule, however, is that if the flapjack is covered in fudge, it will last you 2 months, probably more. Our fruity or cake-topped flapjacks and the brownie and bakewell flapjacks have a shelf life of 3 weeks.

What happens if you eat out of date flapjack? ›

If it has a 'Use By' date, then it usually means it'll go off soon after that date and you probably wouldn't want to eat it. If it has a 'Best Before' date then that just means that it'll be at its 'best' before that date. Eating it afterwards is usually fine, just not as fresh tasting.

Should flapjacks be soft when they come out of the oven? ›

Your flapjack will not look completely baked when you remove it from the oven. Due to the nature of the ingredients, they will still be quite melt-y, but don't worry – it will set as it cools down.

How do you soften flapjacks? ›

Adding flour helps make them chewy and soft. If you missed the flour, that could be the reason. If they do turn hard, leave them in the open air for a few hours to help soften them a little. TIP: You can also store them with a slice of bread to keep them soft, or to help soften hard oat bars.

How do you firm up flapjacks? ›

If your flapjacks appear to be extremely crumbly when cutting, score the top of the bake immediately and put them in the fridge or freezer for a short period to firm up. When you are pressing the mixture into the tin before baking, it's important to pack the mixture in tightly.

How do you rescue dry flapjacks? ›

Would be inclined to try a syrup and melted butter mix and to put the result into the fridge to chill - bit like cheesecake base. Good luck!!

Should flapjacks be runny when cooked? ›

Bake in the oven for approx 30 mins or until it starts to go golden. When you take it out, it will look like the mix is runny – this is normal. Leave on a flat, heatproof surface too cool. When nearly cool, slice into 8 and leave to cool completely.
