First add the softened butter to your sugar and beat them together with your hands in a bowl.
Next add in the flour and knead the mixture together until it forms a smooth dough.
Place the dough onto a smooth surface and rollout the dough to around 1cm thick and cut into fingers.
Line your baking tray with baking paper and place your shortbread fingers onto the tray. Then pop them in the oven for about 20mins.
Place the broken up chocolate into a small bowl and place it over a pot of boiling water until the chocolate has melted.
Once the shortbread is looking golden brown, take them out of the oven and leave to cool on a cooling rack.
You can either dip or drizzle your shortbread with the chocolate and then leave to cool in the fridge.
