Separate egg whites from 3 eggs.
Melt the dark chocolate in a microwave.
In a large bowl, add the egg whites, xanthan gum, erythritol sweetener and pinch of salt. Use a mixer to whisk until the mixture turns fluffy and stiff peaks are formed.
Add the heavy whipping cream, melted dark chocolate, vanilla extract and water into the mixture. Whisk until creamy and ingredients are well-incorporated.
Pour mixture into a plastic container and seal tight with lid.
Place in the freezer for at least 2-3 hours before serving. Enjoy!
