Preheat the oven to 170 degrees fan
In a bowl add your butter, sugar and flour and mix well with your hands until you get until it forms a soft crumbly dough
Once you have a dough, add in your chocolate buttons and give it a mix with your hands (I recommend chopping these up a bit)
Transfer the dough mixture to a baking tray (I used a 20x30cm baking tray and lined this with baking paper) and press down firmly with your hands or spatula
Bake for around 22-26 minutes until pale gold and just set around the edges, don’t worry if you press down on it and it’s soft when you take it out, Nan says that’s perfect !
Leave to cool before slicing and enjoy!!!!
