Preheat your oven to 180 C/350 F/Gas Mark 4. If you have large flaked oats then whizz 50 grams of your measured out oats in the food processor until mostly flour like. Add to the 350 grams of oats in a large mixing bowl. If your oats are standard mixed sized oats then put all your 400 grams in the mixing bowl. Have your non stick baking tin ready. I used a non stick 8" square tin that I lined with bakoglide but baking paper will do the same job.

Place 100 grams dark brown soft sugar - 100 grams light brown sugar- 180 grams unsalted butter - ½ tsp salt - 200 grams golden syrup - in a medium sized saucepan and gently melt it all together whilst stirring. Increase the heat a little until the syrup forms thick bubbles and looks a bit like molten lava. Be careful to only increase the heat moderately. Keep watching as you don't want it burning at all. This bit takes only a minute once all the butter has melted.

Pour that seriously hot syrup onto the oats and being careful not to get any on yourself stir it all in.

Empty it all out into your 8 " square or similar sized tin and spread it out evenly. I find a metal spoon is the best tool for this. Bake for about 15 mins and until the whole thing is a golden brown on top. Not too dark. Watch that the edges don't catch too much. They will be darker than the middle.

Leave to cool in the tin but mark the squares out with a knife before it does so. As they cool they will harden and crisp up. Don't be tempted to eat one before they are completely cold. I recommend putting them in the fridge if you can't wait too long and have even put a square in the freezer because I am crazy for one.
