1. Preheat the oven to 350°F (180°C). Grease and flour a loaf pan (unless using a silicone one), and refrigerate.
2. Wash and dry the cherry tomatoes. Cut them in half, sprinkle with fine salt, and let them drain for a few minutes in a colander.
3. Cut the feta into cubes. Drain the sun-dried tomatoes and cut them into pieces. Separate the basil leaves and finely chop them.
4. In a mixing bowl (or the bowl of a stand mixer), combine the flour, a pinch of salt, and the baking powder. Add the eggs, start mixing, then gradually pour in the oil and milk.
5. Gently fold in the feta, basil, tomatoes, and half of the pumpkin seeds. Pat dry the cherry tomatoes with paper towels and gently mix them into the batter.
6. Pour half of the batter into the loaf pan, spread a layer of tapenade on top, then pour the remaining batter. Sprinkle the remaining pumpkin seeds on top.
7. Bake for about 40 minutes, checking for doneness by inserting a knife blade into the center of the cake - it should come out slightly moist. Let it cool and then remove from the pan.
