Preheat the oven to 190° Celsius (375° F). Lightly butter a baking dish including the sides.
In your mixing bowl break the eggs and use a whisker or a mixer to mix well with sugar.
Then add the yogurt and mix again.
Then add the liquid oil and mix again. For oil you can use a light olive oil, sunflower oil, corn oil or similar.
Then add the flour, semolina, the baking powder and a lemon’s grated zest.
Mix until you obtain a smooth, cake-like texture.
Pour the mixture into the baking dish. Flatten with the back of a spoon or another tool. Tap on the counter if necessary to even and get out any air bubles. Put into the middle rack of the oven.
Cook as if you are cooking a cake. Check the cake’s readiness by sticking in a thin knife or a tooth pick, if it comes out clean, it is a sign that the cake is ready. Take out of the oven.
Cut the cake to serving size squares. Wait for a minute. Pour all the syrup all around the cake evenly. Wait until the syrup is quickly soaked up by the cake.
Garnish with ground pistacho and/or coconut flakes.
Serve warm or cold. Keep in fridge later.
