Ingredients
Method
- Preheat oven to 325°F. Whisk cake flour, 1/2 cup sugar, baking powder, and salt in a large bowl.
- Add egg yolks, oil, orange juice, orange zest, and vanilla; whisk until smooth.
- Beat egg whites and cream of tartar to soft peaks. Gradually add remaining 1/2 cup sugar and beat to stiff, glossy peaks.
- Fold one-third of meringue into the yolk batter to lighten, then gently fold in the rest in two additions until no white streaks remain.
- Pour into an ungreased 10-inch tube pan. Tap to remove bubbles, then bake 50–55 minutes until golden and a tester comes out clean. Cool upside down completely.
- Run a knife around the edges, release the cake, and place on a plate. Dust with powdered sugar or glaze and serve.
Notes
Cooling the cake upside down is the one step you can’t skip; let it hang for at least 90 minutes. If you like a stronger orange presence, brush the warm top with a thin glaze made from powdered sugar and a little more fresh orange juice.
