Place the cottage cheese, cocoa powder, maple syrup, and vanilla extract into a high-speed blender or food processor.
Process on high for 1 to 2 minutes until the mixture is completely smooth and aerated, resembling a mousse texture.
Taste and adjust sweetness if necessary.
Divide the chocolate mixture evenly between two serving bowls or glasses.
Top each portion with fresh raspberries and blueberries.
Garnish with dark chocolate shavings.
Refrigerate for at least 1 hour before serving to allow the texture to set.
