Zlevanka (also called bazlamača, zlevka, kukuruznjača, and a variety of other names) is a traditional peasant pie-like dish that is especially popular in the central and northern parts of Croatia. It consists of eggs, sugar, salt, corn flour, milk, fresh cheese or sour cream, yeast, and oil.

The pie is sometimes enriched with the addition of grated apples or poppy seeds. There is also a unique variety of the dish called Svetojanska zlevanka, unique for the fact that the corn flour must be made in a mill in Sveta Ana, near Đurđevac.

The corn used for the production of the flour must be of an ancient sort and shouldn't be grown on the same field with the hybrid varieties of corn.
