In a blender or food processor, combine the drained silky tofu, cocoa powder, Erythritol, vanilla extract, and a pinch of salt.
Blend until smooth, adding a few tablespoons of almond milk gradually to achieve a creamy and mousse-like consistency.
Taste and adjust sweetness if needed.
Spoon the chocolate tofu mousse into serving bowls or glasses and refrigerate for at least 2 hours before serving.
Optionally, garnish with whipped cream, seasonal low carb fruit, or chopped nuts before serving.
