Melt butter over low medium until it starts to turn golden. Add the nuts. Add 4 tablespoons of the cream and the sweetener. Cook until thickened and golden. This takes about 10 minutes. If it doesn't seem to be thickening you can turn up the heat to medium or medium high but stir constantly. It can burn quickly.
Remove immediately from the heat and add the salt and reserved cream. Stir until smooth.
Pour onto the parchment-lined tray and refrigerate overnight.
