Jamie Oliver Flapjacks are traditional oat bars made by melting butter, sugar, and golden syrup together, then mixing the mixture with rolled oats and baking until just set. The focus is on texture and balance rather than decoration, resulting in a bake that’s hearty, comforting, and unmistakably British.
Preheat the oven to 180°C (160°C fan). Line a square baking tin with baking paper, making sure the paper comes up the sides. This makes lifting and slicing the flapjacks much easier once baked.
Place the butter, golden syrup, brown sugar, and salt into a saucepan. Heat gently over low heat, stirring often, until everything melts into a smooth, glossy mixture. Avoid boiling, as high heat can affect the final texture.
Remove the saucepan from the heat and add the rolled oats. Stir thoroughly until all the oats are evenly coated. This step is important for ensuring the flapjacks hold together and bake evenly.
Transfer the oat mixture into the prepared tin. Use the back of a spoon or spatula to press it down firmly and evenly. Pressing well helps the flapjacks set properly and prevents crumbling later.
Bake in the preheated oven for 15–20 minutes, until the top is lightly golden. A shorter bake gives softer, chewier flapjacks, while a slightly longer bake creates firmer edges.
Remove from the oven and leave to cool in the tin for about 15 minutes. While still warm, lift out and slice into squares or bars. Cutting at this stage gives cleaner edges and prevents cracking.
