Add the cottage cheese, Greek yogurt, pistachio cream, cocoa powder, maple syrup, vanilla extract, and salt to a blender. Blend until completely smooth and creamy. You shouldn't see any cottage cheese curds. I usually blend for about a minute longer than I think I need to. The first time I tested this recipe, a few tiny cottage cheese curds were still visible, and the texture wasn't quite as smooth. Once fully blended, taste and add more maple syrup if needed.
1 1/4 cup cottage cheese, 1 cup thick Skyr or Greek yogurt, ¼ cup pistachio cream, 3 tbsp cocoa powder, ¼ cup maple syrup, 1 tsp vanilla extract, Pinch of salt
