In a large bowl, mix the cottage cheese with the egg yolks, sugar, flour, and vanilla.
In a separate bowl, add the salt to the egg whites and beat until firm peaks form. Fold the egg whites into the cottage cheese mixture in 2 or 3 additions.
Melt butter on surface of griddle or skillet. Drop batter on the skillet and cook until bubbly. Flip and cook for another minute. The pancakes should be light in texture and golden brown on both sides.
