Chocolate Nut Loaf Cake
Grease the loaf pan and line it with parchment paper. Melt the chocolate, marshmallows and butter in a saucepan over low heat, about 5 minutes. Coarsely crumble the cookies. Stir the cookies and nuts into the melted chocolate mixture.
Pour the chocolate mixture into the loaf pan and smooth the top. Freeze for about 1 1/2 hours. Loosen the sides of the cake and unmold. Dust with cocoa powder before serving.
