In another bowl, whisk together the flour, baking powder, baking soda and salt. Gradually whisk the dry ingredients into the wet ingredients. Using a spatula, gently fold in the olive oil. Pour the batter into the prepared pan. Please note that it is a wet batter. Bake the cake for about 45-50 minutes or until the top is golden brown, and a wooden skewer or knife comes out clean when inserted into the center of the cake.
