Add ingredients to a blender. Start with cottage cheese, protein powder, milk, sweetener, vanilla, and a pinch of salt.
If using cocoa powder or nut butter, add those now.
Blend until completely smooth. Scrape down the sides and blend again. You’re looking for a thick, silky consistency with no visible curds.
Adjust texture. If it’s too thick, add milk 1 teaspoon at a time. If it’s too thin, add a little more cottage cheese or a spoonful of protein powder and blend again.
Taste and tweak. Add more sweetener or vanilla if needed.
A tiny pinch more salt can sharpen the flavor.
Chill for best texture. Transfer to a bowl or jars and refrigerate for 30–60 minutes. It firms up and tastes more like pudding after a short chill.
Top and serve. Add berries, shaved chocolate, granola, or a drizzle of peanut butter. Enjoy cold.
