What You Need to Make this Recipe

Butter — essential for richness and flavour, butter is one of the binding agents that holds the oats together, creating a moist texture and golden brown exterior.
Soft light brown sugar — adds a caramel-like sweetness, contributing to the flapjack's golden colour and chewy texture.
Golden syrup — this thick, amber-coloured syrup is key to the unique, sticky sweetness that characterises these treats and also helps to bind the ingredients.
Salt — a pinch of salt enhances the flavours of the other ingredients, balancing the sweetness and adding depth to the overall taste.
Rolled oats — rolled oats provide a hearty texture and are a great source of fibre, making the flapjacks satisfying and nutritious.
How to Make Flapjacks

1. Grab a large saucepan and toss in the butter and soft light brown sugar.
2. Add the golden syrup and a pinch of salt. Heat this mixture over a medium flame, stirring constantly until the butter melts and everything nicely combines.

3. Now, introduce the rolled oats to your saucepan mix. Stir thoroughly, ensuring each oat flake is evenly coated with the buttery, sugary mix.
4. Set your oven to 180°C (356°F) if it's a regular one, or 160°C (320°F) for fan ovens, and get it up to temperature. Also, prep a 20cm (8-inch) square baking tin by greasing it with some butter and then lining it with parchment paper for easy flapjack removal later. Transfer your oat mixture into the previously prepared baking tin. Flatten it out into a nice, even layer with the back of a spoon to ensure even cooking. Slide it into the oven and bake for approximately 20 minutes. You're looking for a lovely golden brown edge while the centre stays slightly soft to the touch. Once baked, allow the flapjack to cool down completely in the tin.

What Are Flapjacks?
Flapjacks are sweet, dense bars made primarily from rolled oats, butter, and golden syrup. They're baked until golden and offer a chewy, satisfying texture. Often confused by name with American pancakes, British flapjacks are a classic, no-fuss treat similar to chewy granola bars. They are perfect for breakfast, snacks, or a sweet pick-me-up with tea. Rich in flavour and simple to make, they embody the comfort of home-cooked sweets.
The Best Oats To Use
To get that perfect chewy feel in your flapjacks, go for porridge oats instead of quick-rolled oats. Rolled porridge oats are a bit thicker and keep their shape better when baked, giving you that hearty, satisfying chew with every bite. Quick-rolled oats might save you some time, but they often end up too soft after baking, making your bars crumbly and not as nice to eat. So, if you're after that classic, chewy texture, porridge oats are the way to go.
Flavor Variations
Mix in a handful of sultanas, chopped dried apricots, sunflower or sesame seeds, or walnuts. You can add spices like 1 teaspoon of ginger or cinnamon to flavour the oat bars. Another lovely ingredient to try is desiccated coconut; mix about 50g of it into your oat mixture before baking. A tasty combination is adding dried cranberries and white chocolate chips for a festive twist, perfect for the holiday season.

How To Keep Flapjacks From Falling Apart
Press the mixture firmly into the baking tin before baking to prevent your flapjacks from falling apart. This compacting action helps the ingredients bind together better upon cooling. Also, it's crucial to cool the flapjacks completely in the tin before slicing. If they're still warm, they might crumble more easily. For an extra tip, a slightly longer baking time at a lower temperature can help the flapjacks set more firmly, reducing the chances of falling apart when cut.
Can I Use Corn Syrup Instead Of Golden Syrup?
Yes, you can use corn syrup as a substitute for golden syrup in flapjacks. Though it will alter the flavour slightly, corn syrup can effectively mimic golden syrup's sticky sweetness and binding properties. This substitution can be convenient if you're in a region where golden syrup isn't readily available. Just remember that the unique taste of golden syrup contributes to the classic flapjack flavour, so using corn syrup may give your flapjacks a slightly different taste profile. I'd recommend using half light and half dark corn syrup if you do need to substitute with it.
Can I Freeze Them?
Absolutely, flapjacks freeze exceptionally well. After allowing the traybake of flapjacks to cool completely, slice the flapjacks, then wrap each piece individually in cling film or place them in a single layer in an airtight container. You can freeze them for up to 3 months. When you're ready to enjoy them, simply thaw them overnight at room temperature or give them a quick warm in the microwave for a freshly baked taste. Freezing flapjacks ensures you always have a quick snack or dessert on hand without compromising flavour or texture.
Pro Tips for Making this Recipe
- Measure ingredients accurately. For the best results, use kitchen scales to measure your ingredients precisely. This ensures the balance of wet to dry components is just right, which is crucial for achieving the perfect flapjack texture.
- Low and slow melting. When combining the butter, sugar, and golden syrup, melt them over low heat. Rushing this process at too high a heat can cause the mixture to burn, affecting the final taste and texture.
- Oven variability. Be mindful of your oven's quirks, as cooking times may vary. Start checking your flapjacks a few minutes before the recommended time to prevent over-baking. If you like your flapjacks crispier, give them an extra five minutes of cooking time.
- Cool before cutting. Patience is key! Allow the flapjacks to cool completely in the tin before cutting them. This helps them set properly and hold together better.
- Slice with a sharp knife. Use a sharp knife to cut the flapjacks. Dip the knife in hot water between slices to make the cutting process cleaner and easier.
- Customise your mix. Feel free to personalise your flapjacks with your favourite add-ins. Remember to keep the ratio of dry to wet ingredients consistent to maintain the right texture.

Frequently Asked Questions
Flapjacks are sweet, dense bars made from rolled oats, butter, and golden syrup, baked until golden and chewy. On the other hand, pancakes are more like what many would recognise as crêpes —thin, flat cakes made from a batter and cooked on a griddle or frying pan. They are often served with sweet toppings like sugar and lemon juice or savoury ones like cheese and ham.
The texture of flapjacks can vary according to personal preference. Traditionally, flapjacks are known for their chewy texture, which comes from the combination of golden syrup, butter, and baking time. However, by adjusting the baking time—baking them slightly longer than recommended—you can achieve a crunchier texture. Whether flapjacks should be crunchy or chewy is up to the baker's or eater's preference.
Flapjacks should be cut when they are cold. This allows them to set properly and firm up, making them less likely to crumble when sliced. Cutting hot flapjacks can cause them to fall apart due to their soft texture. Allow them to cool completely in the tin before slicing them with a sharp knife for best results.
Flapjacks can be made gluten-free by ensuring the oats used are certified gluten-free. Oats do not naturally contain gluten but are often processed in facilities that handle wheat, barley, and rye, leading to cross-contamination. Therefore, for those with celiac disease or gluten sensitivity, it's crucial to use oats that are specifically labelled as gluten-free to avoid any adverse reactions.
