Ingredients
- Oats: The type of oats you use for flapjacks matters! I have tested this recipe with both jumbo oats and regular porridge oats (rolled oats) and I have to say the porridge oats work so much better. The jumbo oats absorb more of the liquid, resulting in a drier, crumbly flapjack which is not the vibe we're going for here.
- Butter: Butter helps to bind the rest of the ingredients together, making it easy to pick your flapjack slices up in one piece after baking. Unsalted butter is the best type to use.
- Brown sugar: This adds sweetness and keeps the flapjacks moist. My favourite kind to use is soft, light brown sugar as it has a milder, caramel-like flavour but you can use dark brown sugar if you prefer.
- Golden syrup: This is essential for the classic British flapjack flavour and texture! If you don't have any, check out my golden syrup alternatives post.
- Dried cranberries: You'll need around 100g of dried cranberries to add to your flapjack mixture. I'd recommend using sweetened ones because cranberries can be quite tart on their own.
Equipment
- Square baking tin: The best size of tin for this flapjack recipe is 8x8 inches. Using this size of tin ensures that the baking time and temperature stay correct. If you want to use a larger tin, you can increase the ingredient quantities using my cake pan calculator. They'll likely take a bit longer to bake but you'll know they're done when they're golden brown at the edges.
- Kitchen scales: Please use a scale and measure in grams for this recipe. I haven't included imperial measurements because they're usually not accurate enough for baking.
- Saucepan: For melting the wet ingredients.
- Bowls and utensils: A large mixing bowl, a small heatproof bowl, a tablespoon, a wooden spoon, and a sharp knife.
- Baking paper: This makes it easier to remove the flapjack from the tin after baking. They can really get stuck in there if you don't line the tin.

How to make cranberry flapjacks
Step 1: First, let's preheat the oven. If you're using a standard oven, set it to 180°C and if you're using a fan oven, it's 160°C.
Step 2: Next, line an 8x8-inch tin with baking paper. You can leave the edges long and use them to lift out the flapjacks later.
Step 3: Add 300g of porridge oats to a large bowl. Set aside.
Step 4: Add 150g butter to a saucepan along with 100g soft light brown sugar and 2 tablespoons of golden syrup. Place the pan over low heat and stir gently until the sugar has dissolved and the butter has melted.
Step 5: Pour the wet mixture into the bowl with the oats and mix well. Then transfer the flapjack mixture to your lined tin and press it evenly into place.

Step 6: Bake for around 20 minutes, until the edges are golden brown. It should still be a little wobbly in the middle when you take it out and will firm up as it cools.

Step 7: Let the flapjack cool for about 5 minutes then use a sharp knife to gently make score marks where you plan to cut it later. This will help you get clean flapjack slices later.
Step 8: Leave it in the tin until completely cool (about 2-3 hours), then gently lift it out and cut it into slices. Then all that's left to do is enjoy!
Flapjack tips
- Use porridge oats for the best chewy texture. Jumbo oats will give you crumbly flapjacks and instant oats will cause them to be too dense.
- Score the flapjacks while they're still warm. This will make it easier to cut them once they've cooled and will help to prevent crumbling.
- Make sure the flapjacks are completely cold before you try to cut them into slices. If you're having a bit of trouble cutting them, you can pop them in the fridge to help them firm up even more.
FAQ
These will last for up to 1 week in an airtight container. Make sure to keep them in the fridge to maintain their chewy texture.
Yes, dried cranberry flapjacks can be frozen for up to 3 months in airtight containers. Alternatively, you can freeze the whole flapjack slab- do this on a baking tray until it becomes solid then wrap it up tightly in clingfilm. For more storage info, check out my post on How To Freeze Flapjacks.
I don't recommend this as the water they contain will cause a soggy texture rather than a chewy one!
Despite seeming like a simple dessert, there are so many things that can change the fate of your flapjacks! I've written a few troubleshooting posts to help you out: Why Do My Flapjacks Fall Apart?, Why Are My Flapjacks Hard?, and Why Are My Flapjacks Greasy?.
Some things that would go nicely with cranberries are white chocolate chips, pistachios or other dried fruits like raisins. I have a list of 50 flapjack flavour ideas if you'd like more inspo!

Easy to make and delicious. My husband asked me not to make them again, as he couldn’t stop eating them! Just made another batch, but added a few pumpkin seeds. Hope they’re as good as the first lot. 🤞
