In a microwave safe bowl, microwave the almond milk and chocolate chips in 30 second intervals, mixing until smooth.
In a bowl of a stand mixer with the whisk attachment, whip the aquafaba, salt, vinegar and cream of tartar until very still peaks form.
Once the chocolate mixture has reached room temperature, mix in a couple of spoonfuls of the stiff aquafaba mixture and fold in using a rubber spatula until just combined. Portion into 6 bowls and refrigerate for at least 3 hours.
