Preheat your oven: 170℃ fan/190℃/Gas Mark 5 (340F).
Prep the tin: Line a 20x20 cm baking tray with baking parchment.
Melt first ingredients, stir in oats and salt: Melt your butter, sugar and golden syrup in a large pan over a low heat. Once the sugar has dissolved, remove from the heat and stir in the oats and salt.
Mix well: Give the entire mixture a really good stir so that all of the oats are coated.
Into the tin: Pour the mixture into your lined baking tin and pat down with the back of a spoon.
Bake: Pop into the oven for 20 minutes. (The edges should be starting to brown but the middle should still be soft and wobbly.)
Slice when cool: When the flapjack is cold, remove it from the tin and slice your flapjacks into 16 squares with a sharp knife.
Finishing chocolate touch: Drizzle over the melted chocolate and allow to set.
