Apple Flapjacks are moist, chewy and super sweet. A fantastic twist on a family favourite and a really easy recipe!
I’d never even considered Apple Flapjacks until one day when I was going to make some chocolate chip flapjacks, and we didn’t have enough chocolate chips for it to be worth it.
I love fruit flapjacks and Bakewell flapjacks, so I’m always happy to have a go at different flavours.
To be honest, I just love oats. Hobnobs will always be my favourite biscuit, and oat and raisin cookies are amazing, and nothing beats an oaty breakfast bar.
Because flapjacks are oaty, I like to think that they are healthy. Which, if we ignore the tons of syrup and sugar I add, is totally true!
It’s worth it, though. Moist apple flapjacks are so soft and delicious, just like all the other kinds of flapjacks, and I absolutely can’t get enough of them.

Can You Make Apple Flapjacks with Apple Sauce?
When I first decided that I was going to make an Apple flapjack recipe, the big question was, chunks of fresh apple or apple sauce?
Robyn loves apple sauce. This means that it’s on all of our Sunday lunch-style family meals. Michael loves Yorkshire puddings, so we always have those too!
Jim wondered if perhaps apple sauce flapjacks would burn. But then we decided that, actually, apple sauce is just apple jam and jam flapjacks are amazing!

So, these are apple sauce flapjacks, just a jar of store-bought apple sauce.
It’s a bit of a cheat, sure, but it’s easy and cheap (Aldi’s own!), so why not?
Ingredients for Apple Flapjacks
One of my favourite things about flapjacks is that you don’t need much! For my apple flapjack recipe, I use:
Oats – Just regular porridge oats, again I use cheap Aldi ones.
Soft Light Brown Sugar
Golden Syrup
Margarine – Use butter if you prefer.
Apple Sauce
That’s it! Soooo easy and perfect for baking with kids.

Can You Put Apple in Flapjacks?
Yes, if you prefer to make Bramley apple flapjacks, you absolutely can.
Personally, however, instead of having big apple chunks, I’d peel and chop the apples into small chunks and simmer them with a little water and sugar to create a sauce to spread in the middle or to mix into the oat mixture.
I just like that sweet, jammy centre.

Another option is leaving them in chunks (I’d say 1-2 cm) and stirring them whole through the oats instead of simmering to create a jam. You could also add a teaspoon of cinnamon to make apple and cinnamon flapjacks.
How to Make Flapjacks with Apple Sauce
You basically just melt the butter, sugar and syrup together, stir it through the oats, tip half into a pan, squash flat, spread apple sauce and then top with the oats.
You can get the full recipe in the card at the bottom of this post.
How Do You Make Gooey Flapjacks?
These apple flapjacks have a lot of butter, sugar and syrup, so unless they are overbaked, they’ll be very moist and gooey.
Why Do My Flapjacks Fall Apart?
Flapjacks are oaty, which means that they’ll always be a little crumbly. If they weren’t, they’d be super hard, and that wouldn’t be good. So don’t worry about a little falling apart.
If, however, they fall apart that much, you can’t hold them, I recommend cutting them into smaller squares or bars. I like mine fairly big, but you could easily get 16 out of this recipe instead of 8.
I also find that they tend to fall apart more if you move and cut them when they are still hot.

When your flapjacks with apple sauce come out of the oven, either leave them in the tin on the side to cool completely or, if you can’t wait, pop the tin in the fridge until they are cool.
Then, remove from the tin, peel off the baking paper, and cut carefully with a sharp knife.
How Long Do Apple Flapjacks Last?
In our house, about a day!? I love apple crumble, and these are a bit like bars of it, so they don’t last for long!
But in general, flapjacks, if kept in a sealed tub, will last for 3-4 days. They will get softer in time, but that’s not such a bad thing.

Can You Freeze Apple Flapjacks?
Yes. Flapjacks freeze really well.
I recommend wrapping them individually in cling film or wax sheets before putting them in an airtight tub and freezing, or at least putting a bit of reusable baking paper between them so that they don’t stick together.
You can freeze these apple flapjacks for up to 3 months.

Apple Flapjacks
Ingredients
- 300 g Porridge Oats
- 115 g Soft Light Brown Sugar
- 150 g Golden Syrup
- 180 g Butter or Margarine
- 6 tablespoons Apple Sauce
Instructions
- Preheat the oven to 180 degrees and line a deep baking tray.
- Pour the oats into a large mixing bowl.
- In a small saucepan over a low heat, melt together the butter, sugar and syrup, stirring constantly until the butter is melted and there are no lumps– do not let it come to the boil.
- Pour this mixture over the oats.
- Mix carefully until the oats are all wet.
- Spoon around half of the oats into the baking tin.
- Use a spoon or your fingers to press down, and out to the edges until you’ve got a flat, even layer.
- Spoon on the apple sauce and use the back of a metal spoon to spread evenly.
- Spoon on the remaining oats, and use your fingers or a spoon to spread to the edges and press down so that most of the sauce is covered.
- Bake in the oven for around 25-30 minutes, until the top is golden brown.
- Leave in the tin to cool completely, before tipping out, peeling away the paper and slicing.

Notes
- I make my apple flapjacks in my brownie tin, which is around 10 inches x 8 inches which means they are fairly thin. I wouldn’t use a bigger tin, but you can use a smaller tin. I sometimes use a square cake tin, so they are thicker. Just increase the bake time by 5-10 minutes.
- Don’t worry if not all the sauce is covered or if some pokes through.
