In a large bowl, mix the ground almonds, cocoa powder, sugar substitute, and salt.
Add the almond butter, cream, and vanilla extract.
Mix the ingredients well until combined and a cohesive dough forms.
Shape the dough into small balls, about the size of a teaspoon.
Roll the balls in the chopped almonds or cocoa powder for coating.
Place the balls in the refrigerator for at least 30 minutes to firm up.
Serve the chocolate balls cold.
