In a small saucepan, heat the butter and chocolate chips over low heat. Stir constantly until the butter is melted and the chocolate chips are smooth.

Remove from the heat and add the vanilla extract. Mix well.

Allow the chocolate mixture to cool for 10-15 minutes.

Cut two pieces of 14” wax paper. Lay them flat on the countertop.

Sprinkle ¾ cup of shredded coconut on each piece of the wax paper.

Place the chopped walnuts and mini marshmallows in a large bowl.

Pour the chocolate over the nuts and marshmallows. Use a rubber spatula to mix well.

Divide the mixture in half.

Place one half on each piece of wax paper. Shape carefully into two logs. Sprinkle the tops of the logs with the remaining coconut.

Roll the logs up tightly in wax paper.

Refrigerate the logs for at least two hours.

To get clean slices, freeze the logs for about 15-20 minutes, then unroll from the wax paper and use a sharp knife to cut slices.

Store in an airtight container.
