In a slow cooker, whisk together eggs, cream, and salt until blended.
Add the chocolate chips, stir, and then cover with lid. Turn the slow cooker on high to melt the chocolate about 30 minutes, then whisk until completely blended.
Turn the slow cooker down to low heat and cook for another 30 minutes. Scrape the sides down of the slow cooker and whisk until smooth.
Cook another hour, the edges will be slightly set but the center will be a soft pudding consistency.
Serve warm and just before serving whisk the pudding again smooth. Spoon into cups or mugs and top with a generous amount of marshmallow cream and garnish.
