Directions

1. Melt the butter in a large saucepan, remove from heat.
2. Stir in the xylitol with a wooden spoon. Cool to room temperature.
3. Add the cream cheese and beat with a mixer until the mixture is free from lumps.
4. Add the cocoa powder and beat until well incorporated.
5. Fold in the walnut pieces and chocolate chips.
6. Line a loaf pan with a piece of parchment paper large enough to go up the sides. This will make it easier to remove the fudge from the pan.
7. Smooth the mixture into the loaf pan and refrigerate several hours, or until firm.
8. Remove the fudge from the pan by pulling up the edges of the parchment paper.
9. Cut into squares and serve.
