Preheat & Prepare Pan Preheat your oven to 175°C (350°F). Grease and line a loaf pan or a small round cake pan (about 20 cm / 8 inch) with parchment paper.
Whisk Sugar & Oil In a large bowl, whisk together the olive oil and granulated sugar until well combined and slightly creamy.
Add Eggs, Zest & Juice Add the whole egg, egg yolk, vanilla extract, lemon zest, and lemon juice. Whisk until smooth and well incorporated.
Mix Dry Ingredients In a separate bowl, stir together the flour, baking powder, baking soda, and salt.
Combine & Add Milk Add the dry ingredients to the wet mixture and stir until just combined. Then pour in the milk and mix gently until the batter is smooth, don’t overmix.
Pour & Sprinkle Pour the batter into your prepared pan. Sprinkle the extra tablespoon of sugar evenly on top for a light crunch.
Bake Bake for 35–40 minutes, or until golden and a toothpick inserted into the center comes out clean.
Cool & Finish Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. Dust with powdered sugar before serving if you like.
