A light and airy sponge-style cake with rich moisture and soft crumb — perfect for fruit toppings, whipped cream, or simple glazes.
2 1/4 cups cake flour
1 1/2 cups granulated sugar (divided)
1 tbsp baking powder
1/2 tsp salt
7 large eggs, separated
1/2 cup vegetable oil
3/4 cup water (or citrus juice)
1 tsp vanilla extract
1/2 tsp cream of tartar
Optional: zest of 1 lemon or orange
Preheat oven to 325°F. Do not grease a 10-inch tube pan.
Sift flour, baking powder, salt, and 3/4 cup sugar into a large bowl.
In another bowl, whisk egg yolks, oil, water, vanilla, and zest. Combine with dry ingredients.
Beat egg whites with cream of tartar until foamy. Gradually add remaining sugar. Beat until stiff peaks form.
Fold egg whites into batter gently in 3 additions.
Pour into pan. Smooth top.
Bake 50–60 minutes until springy and golden.
Invert pan to cool completely upside down.
Run a knife around edges to release. Serve plain or with toppings.
Store covered for 2 days at room temp or refrigerate for longer.
Great with whipped cream, fruit, or citrus glaze.
