- Whisk egg yolks with half the sugar until pale, then add oil, milk, water, and vanilla.

- Beat egg whites until foamy, add cream of tartar, then gradually add remaining sugar and whip to stiff peaks.
- Fold egg whites into batter gently in batches.
- Pour into pan and bake for 40–50 minutes until set.
