This recipe provides instructions for making best-ever brownies that are squidgy and chocolately. The brownies are made by melting butter and dark chocolate together and mixing it with eggs, sugar, flour, cocoa powder, and chocolate chunks. The mixture is poured into a tin and baked for 25 minutes until the top has a shiny crust and the sides start to come away from the tin. It is then cooled completely before cutting into squares or triangles.
