Preheat the oven to gas 4 / 180C / 350°F and grease a shallow 7 x 11" tin

Put the butter, sugar and syrup in a saucepan and heat until the sugar is dissolved

Remove from the heat and add in the oats and extras of choice. (I added 50g finely chopped dates, 30g Enjoy Life free-from chocolate chips, 20g sunflower seeds and 15g dessicated coconut)

Stir in well, the mixture will be very stiff. If it gets too stiff to stir, put it back on the heat to loosen it

Spoon into the greased tin and flatten down with the back of a spoon

Bake for 20 minutes until lightly golden. It will still look soft but it will harden up as it cools down so don't be tempted to overbake

If you like, melt 100g safe chocolate and spoon or drizzle over the flapjacks in the tin when they've cooled 5 minutes, then place in the fridge for half an hour to set
