Place chopped chocolate in a microwave safe container. Microwave the chocolate in 30-second increments, stirring in between each interval until the chocolate is completely melted.
Add yogurt to a medium bowl and pour the melted chocolate over the yogurt and whisk for a full minute.
Divide the mixture between 2 small jars or ramekins, cover with plastic wrap, and refrigerate for at least 2 hours to thicken before serving.
