Put the chocolate chips in a heatproof bowl and melt in the microwave for 2 – 3 minutes on high power, stirring every 30 seconds until melted. Alternatively you can melt the chocolate in a heatproof pan over a pan of simmering water making sure the bottom of the pan does not touch the water. Put the melted chocolate in the bowl of a stand mixer along with the Sunbutter and vanilla.
Bring the milk and salt to a boil and add half of the milk to the chocolate and Sunbutter. Blend on low speed to combine. Add the remaining milk and blend until smooth on low speed. Increase the speed to high and whip for 5 minutes or until the mixture has cooled.
In a clean bowl with clean beaters, whip the cream until stiff peaks form. Take about a quarter of the cream and mix with the chocolate Sunbutter mixture. Fold in the remaining cream until no longer streaky. Scrape the mixture into an 8 inch square baking pan and refrigerate for 4 hours. Garnish with optional garnishes if desired.
Cut into small gluten free chocolate squares and serve.
