Blend the base: Add cottage cheese, cocoa powder, protein powder, milk, sweetener, vanilla, and a pinch of salt to a high-speed blender. Start on low, then increase to high.
Scrape and smooth: Stop and scrape down the sides once or twice to catch any cocoa or cottage cheese bits.
Blend until completely smooth and glossy, about 30–60 seconds.
Adjust texture: If it’s too thick, add milk 1 teaspoon at a time and blend again. If it’s too thin, add a little more protein powder or cocoa and re-blend.
Taste and tweak: Adjust sweetness and salt. A tiny extra pinch of salt can make the chocolate pop.
Chill: Spoon into jars or bowls.
Chill for at least 20–30 minutes for a thicker, set texture. You can also enjoy it right away if you like it softer.
Top and serve: Add your favorite toppings just before serving. Keep it simple with berries, or go richer with dark chocolate shavings.
