Baked Blintzes are a traditional Polish dessert. They are made from a cornstarch batter, and are typically served at a brunch. The batter may be watery when it's fresh, so you'll need to allow them to cool before slicing them into squares. Afterwards, they'll be set up and easier to cut into neat squares. During the summer, you can serve them with berries or blueberry jam.
