Nut-free Chewy Flapjacks with Sultanas
Chewy, golden oat flapjacks with sultanas — nut-free, quick to make and perfect for lunchboxes or a teatime treat.
Flapjacks are Britain's unofficial comfort traybake — simple, satisfying and endlessly tweakable. These are classic, chewy oat bars studded with sultanas and kept strictly nut-free for safe lunchboxes.
They come together in under half an hour on the hob and a single bake. Press them while hot for the proper chewy texture; overbake and you'll end up with crumbs, not bars.
Ingredients
- 400 g rolled oats
- 175 g unsalted butter
- 100 g soft light brown sugar
- 100 g golden syrup
- 100 g sultanas — optional for extra chew and sweetness
- 5 ml vanilla extract
- 0 ml fine salt
Equipment
- 20 x 30 cm baking tin
- baking parchment
- medium saucepan
- spatula
- cooling rack
Instructions
Preheat the oven to 180°C fan/200°C conventional. Line a 20 x 30 cm baking tin with baking parchment, leaving a little overhang to lift the flapjacks out later.
Put the unsalted butter, soft light brown sugar and golden syrup into a medium saucepan over low heat. Stir constantly until the butter melts and the sugar has dissolved — about 3–5 minutes. Do not let it boil vigorously.
Remove the pan from the heat. Stir in the vanilla extract and fine salt, then tip in the rolled oats and sultanas. Mix thoroughly until every oat is coated with the syrupy mix — about 1 minute.
Tip the mixture into the prepared tin and press down firmly and evenly with the back of a spoon or a piece of baking parchment to compact the oats.
Bake in the middle of the oven for 18 minutes, until the edges are turning golden and the centre still looks slightly soft.
Remove the tin from the oven and, while the flapjack is still hot, press down firmly again to compact the surface. Leave to cool in the tin for 15 minutes so the bars set.
Score into 12 bars with a sharp knife while still warm, then lift out using the parchment and transfer to a cooling rack. Leave to cool completely for 30 minutes before separating fully.
Once cool, separate along the scores and store in an airtight container at room temperature for up to 5 days.
Tips
- Press the mixture firmly into the tin while hot and again straight from the oven — this is the single best trick for chewy, clean-edged bars.
- To make extra-chewy flapjacks, reduce the bake time by 2 minutes; for crispier ones, add 3–4 minutes but watch closely.
- Line the tin with a single long sheet of baking parchment with an overhang on two sides — it makes lifting the whole slab out foolproof.
- Store between sheets of baking parchment in an airtight container to keep them from sticking together; they keep well for up to 5 days.
- For school lunches, check all ingredient labels for ‘may contain’ warnings to avoid cross-contamination with nuts.

FAQ
How do I make these dairy-free?
Use a solid dairy-free baking spread (one formulated for baking) in place of the butter and check the golden syrup label. Texture will be very similar if the spread has a high fat content.
Can I freeze flapjacks?
Yes — individually wrap cooled bars in baking parchment and freeze in an airtight box for up to 3 months. Defrost at room temperature for 1–2 hours before eating.
Why did my flapjacks crumble?
Most likely under-pressed or overbaked. Press firmly into the tin while hot and avoid baking beyond the point where the centre still looks slightly soft — they firm up as they cool.
Can I add seeds or chocolate?
Yes — sunflower seeds or pumpkin seeds work well (check labels for nut-free status). Chocolate chips are fine but stir them in after the mixture has cooled a little to avoid melting.
