Whisk eggs and sugar for 2–3 minutes until slightly thickened and paler. Whisk in olive oil in a slow stream.

Pour into the prepared pan. Bake for 35–45 minutes until golden, the center springs back gently and a skewer comes out without wet batter.

Cool in the pan for 15 minutes, then unmold onto a rack for at least 30 minutes before slicing. Serve plain to enjoy the orange flavor.

Wrap the cooled cake and keep in a cool room for up to three days. Freeze slices individually for longer storage.
