  • 375g unsalted butter or baking margarine
  • 225g golden syrup
  • 200g soft brown sugar
  • 500g porridge oats


  1. Set oven to gas mark 3, 160 C.

  2. Grease a 20x30cm baking tray and line the bottom with baking parchment.

  3. In a large saucepan melt butter, sugar and syrup until all mixed and runny.

  4. Take the saucepan off the heat and stir in the oats until all combined.

  5. Pour the mixture into the prepared baking tray and smooth even with a spatula.

  6. Place in the centre of the pre-heated oven and bake for 20 - 25 minutes, until golden. (If you prefer a more chewy flapjack, it should still have a slight wobble when you take it out of the oven).

  7. Allow to cool in the tin for 15 minutes, then mark lightly where you want to cut into squares. Cover with a clean tea towel until completely cooled.

  8. Cut into squares and turn out.

Increase the oats to 650g if you don't like the butteryness of this dish

Very nice, but how do I make them harder? Cook the, longer/slower/lower temperature? They are a bit oily, maybe a longer cook at a lower temp would allow the butter to absorb into the oats more?

Far too much butter. The flapjacks were stodgy and unpleasantly greasy and fell apart, even after longer cooking.

This quantity will fit into a traditional Swiss roll tin, 20x30cm but as it's only 2cm in depth, spills out as it's cooking (and makes an unnecessary sticky mess). Spread it into two tins with these dimensions and you can cut it into 16 fingers when cool.
