Melt the cocoa butter in a microwave or small saucepan over low heat.
Transfer the cocoa butter to a medium bowl, add all the other ingredients and mix well; Taste and adjust seasoning if necessary.
Line a 4-inch diameter springform pan with cling film; transfer the mixture to the pan, cover the top with the cling film, and place in the refrigerator to set for about an hour - until the parmesan hardens.
Instead of using a spring mold, you can make personal mini Parmesan in the shape of hearts, flowers, etc. - pour the mixture into silicone praline molds and place it in the refrigerator to set.
Remove the parmesan from the mold, put it in a sealed plastic bag (or wrap it well in a cling film) so the parmesan does not dry out, and keep it in the refrigerator. If you make mini parmesans, remove them from the silicone mold and store them in a sealed box.
The Parmesan keeps in the fridge for a long time.
