Chocolate and cranberry flapjacks

I haven't made flapjacks for ages. Each time, I change my original recipe and add new things; today it's cranberries and sunflower seeds.

125 gr butter
75g caster sugar
1 tbspn golden syrup
300g rolled oats
50g sunflower seeds
75g chocolate chips or chopped dark chocolate
50g dried cranberries

Preheat oven 180C/350F/gas4
Grease a 20cm square cake tin.
Put the butter, sugar and syrup in a pan and melt over a low heat. Mix well.
Take off the heat and add the oats and sunflower seeds. Stir until well mixed, then add the chocolate chips and cranberries.
Spoon into the cake tin and press it down well with the back of a spoon.
Bake for 25 mins.

Let it cool in the tin for a bit, then mark into 12 squares.
