This chocolate loaf requires no cooking except for melting the margarine, which can be done in the microwave if you happen to have one. Rather, to make it, you simply crush store-bought cookies (shortbread is a good option here) and whisk the crumbs with cocoa powder and sugar before combining with beaten eggs and finally the cooled margarine (make sure it is no longer warm). Then this mixture is shaped into a ball, wrapped in parchment, and tucked into the refrigerator to harden before slicing and serving.
