Add butter, Swerve, cinnamon and cayenne pepper to large sauce pan and heat on medium-high heat until the butter is browned well (just not burnt) and the Swerve is COMPLETELY melted. While this is cooking, spread your nuts evenly onto a cookie sheet covered with parchment paper. Pour your melted "sauce" over the nuts, sprinkle with pink salt & place in fridge and allow to cool & harden. Once your nuts harden, break into pieces and place in a decorative jar or small gift bags to make an adorable, healthy gift for Christmas, Easter, birthday parties, or just to keep on hand for your family!!
NOTE: This works better on a gas stove. If you use an electric stove, finding the balancing between melting the Swerve fully but not burning it is a bit tricky. If you make this and the sauce never hardens, you didn't cook it long enough. If it tastes burnt or gets black (instead of darker brown), then you went too long or had the heat too high.
