Ingredients
Egg White Batter
- 6 large egg whites
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon vanilla extract
- 2/3 cup sugar
- 1/2 cup cake flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
Yellow Batter
- 6 large egg yolks
- 2 tablespoons warm water
- 1/2 cup cake flour
- 1/2 cup sugar
- 1 teaspoon baking powder
- 1/8 teaspoon salt
- 1/2 teaspoon vanilla extract
Frosting
- 1/2 cup sugar
- 4 teaspoons all-purpose flour
- Pinch of salt
- 1 cup pineapple juice
- 1 carton (8 ounces) frozen whipped topping, thawed
Instructions
- Prep the white batter: Place the egg whites in a large bowl and let them stand at room temperature for 30 minutes. Preheat the oven to 350°F. Add cream of tartar and vanilla to egg whites. Beat on medium speed until foamy. Gradually add sugar 1 tablespoon at a time, beating until soft peaks form. In a separate bowl, combine cake flour, baking powder, and salt. Gently fold dry ingredients into egg whites, then set aside.
- Prep the yellow batter: In another large bowl, beat egg yolks and warm water until thick and lemon-colored. Combine cake flour, sugar, baking powder, and salt. Gradually beat dry ingredients into the egg yolk mixture. Beat in vanilla extract.
- Spoon the cake batters into the tube pan: Alternate spoonfuls of yellow and white batter into an ungreased 10-inch tube pan for a marbled or layered effect.
- Bake the cake: Bake at 350°F for 35 to 40 minutes, or until a toothpick inserted into the center comes out clean. Immediately invert the pan and let the cake cool completely in the pan to maintain its structure.
- Make the whipped pineapple frosting: Combine sugar, flour, and salt in a small saucepan. Stir in pineapple juice until blended. Bring to a boil and cook, stirring, for 2 minutes until thickened. Remove from heat and let cool completely. Once cooled, fold in the thawed whipped topping gently.
- Frost and serve the cake: Carefully remove the cake from the pan onto a serving plate. Spread the pineapple whipped frosting evenly over the top and sides of the cake. Serve and enjoy.
Notes
- Letting egg whites stand at room temperature helps them whip better for a lighter texture.
- Careful folding preserves the airiness of the whipped egg whites, essential for a fluffy cake.
- Inverting the pan immediately after baking prevents the cake from collapsing as it cools.
- Use an ungreased tube pan to help the cake climb the sides and maintain height.
- Ensure the pineapple frosting mixture is fully cooled before folding in the whipped topping to maintain fluffiness.
