Step 1

Preheat oven to 350 degrees F (175 degrees C). Lightly oil and flour a loaf pan.

Step 2

Beat eggs in a bowl until lightened in color. Add sugar, olive oil, orange zest, and five-spice powder and beat until smooth. Fold flour, baking powder, and salt into egg mixture until batter is just mixed. Pour batter into the prepared loaf pan.

Step 3

Bake in the preheated oven until a toothpick inserted in the center comes out clean, about 45 minutes. Cool in the pan for 10 minutes. Remove cake from the pan and cool on a wire rack.
