How to Make Delia Smith Flapjacks

Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line a 20 x 30cm baking tin with parchment, leaving an overhang for easy removal.
Melt the mixture: In a saucepan over low heat, gently melt the butter, sugar, and golden syrup together until smooth and fully combined. Stir occasionally to prevent burning.
Mix the oats: Remove from heat and stir in the oats and a pinch of salt. Mix thoroughly until all the oats are evenly coated.
Transfer to tin: Spoon the mixture into the prepared tin and press it down firmly using the back of a spoon to create an even layer.
Bake: Bake in the preheated oven for 20–25 minutes until golden brown around the edges.
Cool and slice: Allow to cool in the tin for 10 minutes, then score into squares while still warm. Leave to cool completely before removing and cutting fully.

Tips

Why are my flapjacks too crumbly?

This usually happens if there is not enough syrup or butter. Make sure measurements are accurate and press the mixture firmly into the tin before baking.

How do I get chewy flapjacks?

For a chewy texture, bake for the shorter time and avoid overbaking. The centre should still feel slightly soft when removed from the oven.

Can I add extras?

Yes, you can stir in raisins, chocolate chips, or chopped nuts after mixing the oats for added flavour and texture.

Why are my flapjacks too hard?

Overbaking is the main cause. Keep an eye on them and remove once lightly golden, as they firm up further while cooling.

FAQs

Why are flapjacks called flapjacks in the UK?

In the UK, flapjacks refer to baked oat bars made with butter, sugar, and syrup, unlike American flapjacks which are pancakes.

Can I use quick oats instead of rolled oats?

Yes, but the texture will be softer and less chewy. Rolled oats are recommended for the best result.

How do I know when flapjacks are done?

They should be golden around the edges but still slightly soft in the centre. They firm up as they cool.

Can I reduce the sugar?

You can slightly reduce the sugar, but too little may affect the structure and texture of the flapjacks.
