Lazy Borek — Tray-Baked Savory Pastry with Pourable Batter

Whisk together the milk, eggs, oil, and salt. Sift in the flour and baking powder and whisk for 3 minutes, until no lumps remain. The batter should fall from a spoon in a thick ribbon, thicker than crepe batter but looser than cake batter. If it seems too thick, add 50 ml milk.

Pour one-third of the batter into a greased pan and tilt the pan to spread it. Sprinkle half the cheese filling on top. Repeat this sequence once, then pour the remaining batter over the top. Keep the filling away from the edges; cheese at the edges will darken in the oven.

Sprinkle the sesame seeds and nigella seeds over the surface, then tap the pan lightly once on the counter; this helps the batter settle between the layers of filling.

Bake in an oven preheated to 180°C / 355°F for 45 minutes. It is done when the top is golden and a knife inserted in the center comes out clean. This borek rises in the oven and settles somewhat after it comes out; that is normal.
