1. Preheat the oven to 180°C (350°F). Grease and flour a round cake pan with a hole in the center, 24-26cm in diameter.
2. In one bowl, mix the Halloumi, Anari, and mint. In another bowl, mix the flour, baking powder, mastic, and mahlab.
3. Add the raisins and mix them into the dry ingredients. This will help the raisins distribute evenly throughout the cake and prevent them from sinking to the bottom of the pan.
4. Crack the eggs into a bowl and beat them well with an electric mixer until fluffy, about 5 minutes. Add the sugar and continue beating for another 3 minutes until the mixture is light and pale. Reduce the mixer speed and add the oil. Add the evaporated milk.
5. Add the cheese mixture one spoonful at a time, followed by the flour mixture one spoonful at a time. Stop the mixer and scrape down the sides of the mixing bowl. Pour the batter into the cake pan and sprinkle with sesame seeds. Bake for 50 minutes. To check if it's done, insert a wooden skewer into the center of the cake; if it comes out clean, it's ready. Let the cake cool slightly, then turn it out onto a rack and serve.
