These Nutella flapjacks are soft, chewy and super easy to make. Classic British flapjacks stuffed with Nutella make for a tasty treat that the whole family will love!

I'm back with another flapjack recipe and today it's my delicious Nutella flapjacks! If you're looking for a quick and easy dessert that's great for serving a crowd, meal prepping or grabbing on the go, these are just the thing.

I have to be honest and say that I had to test this recipe quite a few times! I started by adding Nutella to my usual gooey flapjack mixture. The texture turned out great but the flavour was not quite right- it had neither a strong Nutella flavour nor that classic buttery flavour.

After a few more adjustments and failed attempts, I decided to try just sandwiching the Nutella in between my regular flapjack mixture. This resulted in a much better flapjack-to-Nutella flavour ratio, and I'm excited to share the recipe with you!

Ingredient list

Oats: As with all my flapjacks, I recommend using porridge oats (rolled oats) for this recipe. They'll give a nice sturdy hold without making creating hard flapjacks.
Brown sugar: Use soft, light brown sugar for best results. You can use dark brown sugar if you don't mind a more molasses-like flavour, or caster sugar for a sweet but neutral flavour.
Golden syrup: Golden syrup is a must-have ingredient in any good flapjack recipe. You'll find this amber-coloured syrup in the baking aisle or beside the sugar in supermarkets. Check out my golden syrup alternatives post if you don't have any to hand.
Butter: Melted butter will help to bind the oats together and produce a chewy texture. I recommend using salted butter.
Nutella: The star of the show, Nutella! I filled my flapjack with 100g of Nutella but if you want to add more, by all means, go for it! I'd recommend a max of 200g to prevent it from spilling out the sides.

Equipment

Kitchen scales: For accuracy when baking, please measure in grams using a scale. I haven't included imperial measurements because they can be vastly different from one person to the next and cause recipe failure.
8x8 tin: Use this size of tin for the best thickness and a chewy texture. You can use a different size tin but note that the thickness will change and the baking time/temperature may vary.
Baking paper: To stop the flapjack from sticking.
Saucepan: For melting all the wet ingredients together.
Heatproof bowl: To melt the Nutella briefly.
Mixing bowl and utensils: You'll need a large mixing bowl to mix the flapjack mixture (or you can use your saucepan if it's large enough), a wooden spoon for mixing, and a sharp knife for cutting. Although not essential, a rubber spatula is another handy tool to have. It's great for pressing the mixture firmly into the tin because it doesn't stick.

How to make Nutella flapjacks step-by-step

Step 1: Preheat your oven to 180°C (or 160°C if you're using a fan oven) and line an 8x8-inch tin with baking paper. You can leave a bit of baking paper hanging over each edge to make it easier to lift out once the flapjacks have set.

Step 2: In a large saucepan, melt 150g butter, 120g soft light brown sugar and 2 tablespoons golden syrup together over low heat. Stir gently until the butter has melted and the sugar has dissolved. Melting the sugar will help bind the mixture together, preventing your flapjacks from falling apart.

Step 3: Remove the pan from the heat and stir in 300g of porridge oats. Mix well until the oats are well coated with no dry or sticky patches.

Step 4: Put half of the flapjack mixture into your lined tin and press it down firmly into place.

Step 5: Put 100g of Nutella into a heatproof bowl and microwave it for 10-15 seconds to make it runny. Then spread it evenly over the flapjack in the tin. 'Melting' the Nutella first will make it easier to spread without sticking to the flapjack.

Step 6: Top with the rest of the flapjack mixture and press it down firmly into place using the back of a wooden spoon or rubber spatula.

Step 7: Bake your Nutella flapjack for 20 minutes until golden at the edges. The middle might look a little wobbly when you first take it out but don't worry- it'll firm up as it cools.

Step 8: Let the flapjack cool in the tin for about 5 minutes then gently score it with a knife where you plan to cut it later (this helps you get clean flapjack slices). Leave to cool completely in the tin, around 3-4 hours.

Step 9: When the flapjack has completely cooled, remove it from the tin and cut it into slices using your score marks as a guide. Then all that's left to do is enjoy!

Top tips

Press the mixture into the tin firmly to prevent the flapjacks from crumbling after baking. A rubber spatula is great for doing this because it won't stick to the flapjack mixture.
If your flapjacks are greasy or fall apart when you cut into them, pop them into the fridge for an hour or two. This will help them set faster, creating a sturdy texture.
I used 100g of Nutella but if you want an extra indulgent dessert, feel free to increase this amount. You could also add a drizzle of Nutella on top of the slices if you like.
For some extra fun, you can add white chocolate chips, chopped hazelnuts, or any of these flapjack mix-in ideas!

FAQs

How long do Nutella flapjacks last?

These will last for up to 1 week if you keep them in an airtight container. They're best stored in the fridge for that classic chewy texture.

Can I use honey instead of golden syrup?

You sure can, although it's important to note that the flavour will be a little different. Check out my honey flapjacks recipe.

Can this recipe be frozen?

Yes. Freeze your flapjacks in an airtight container for up to 3 months. When you're ready to defrost them, transfer them to the fridge and leave them there overnight. I have a whole post on freezing flapjacks if you'd like to learn more!
