Add the cottage cheese, eggs, cocoa powder, maple syrup or honey, flour, and vanilla to a blender.
Blend until completely smooth, stopping to scrape down the sides as needed.
Pour the batter into a parchment-lined 6-inch round baking dish and smooth the top.
Bake at 325°F (165°C) for 45 to 50 minutes, until the edges feel set and the center is still soft and slightly jiggly.
Transfer to the refrigerator and chill for at least 8 hours, preferably overnight, before slicing.
