The Easiest shortbread in the world

This really is the easiest shortbread in the world, super quick to make, light and buttery and is so good with a big mug of tea. This version is a chocolate chip one but I love swapping regular caster sugar for lavender or vanilla infused sugar to make it that little bit more extravagant. 

To make 9 chunky squares or 12 ( almost ) bitesize pieces you will need 

250g unsalted softened butter 
125g caster sugar
250g plain flour
125g cornflour
50-75g chocolate  chips

• Preheat your oven to 150c /300f and grease an 8 inch square tin
• In a bowl cream the butter and sugar till light and fluffy
• Add in the plain flour, corn flour and chocolate chips and mix together with a wooden spoon till it just starts to come together. Use your hands to lightly press it all together*
• Transfer the dough into the greased tin and gently press it out into the whole of the tin.
• Prick it all over with a fork, and place in the oven for 50 -55 minutes till it's lightly golden all over.
• Whilst its still a little warm (not hot) sprinkle a little caster sugar all over and once cooled, cut into 9 chunky pieces or 12 smaller almost bitesize pieces. 

* If you prefer you can wrap the dough in cling film, let it chill for about 10 minutes in the fridge, then on a lightly dusted surface, roll out to about an inch thick and transfer to the tin
