This is going to make a great addition to my holiday tray. I melted the chocolate over simmering water rather than the microwave. You have to move quickly to get this to shape nicely. I found measuring the marshmallows, nuts ahead of time worked best. I formed this amount into two logs, made a nice sized slice. Mine were something between round and square but it made no difference to me. Took 2 hours in the fridge. Ive made this twice now and the first time I used milk chocolate chips and do prefer the semi sweet better. Made for PAC fall 09.
