Ingredients
Egg Whites and Dry Ingredients
- 12 large egg whites, room temperature
- 1 1/2 cups granulated sugar, divided
- 1 cup cake flour, sifted (or homemade substitute: 1 cup all-purpose flour minus 2 tbsp, plus 2 tbsp cornstarch, sifted)
- 1/2 teaspoon cream of tartar
- 1/4 teaspoon salt
Flavorings and Fruit
- 1 tablespoon fresh lemon zest
- 1 teaspoon vanilla extract (or lemon extract for extra lemon flavor)
- 1 cup fresh blueberries, lightly coated in 1 tablespoon flour
Instructions
- Prepare the egg whites: Ensure egg whites are at room temperature for maximum volume. Separate the eggs the night before and let whites rest covered, or warm them for 30-60 minutes before use.
- Sift dry ingredients: Sift cake flour together with 1/2 cup of granulated sugar multiple times to aerate and combine. This helps create an ultra-light texture.
- Whip egg whites: In a clean, grease-free bowl, beat the egg whites on medium speed until foamy. Add cream of tartar and salt, then gradually add the remaining 1 cup sugar in small increments while whipping. Continue until firm, glossy peaks form.
- Fold in flavorings: Gently fold in lemon zest and vanilla extract into the whipped egg whites to evenly distribute flavor without deflating the mixture.
- Incorporate flour mixture: Carefully fold the sifted cake flour and sugar mixture into the egg whites in batches. Use a gentle folding motion to maintain air and volume.
- Add blueberries: Lightly toss the fresh blueberries in flour to prevent sinking, then gently fold them into the batter last to evenly disperse without breaking the fruit.
- Transfer to pan and bake: Pour the batter into an ungreased angel food cake pan. Bake in a preheated oven at 325°F (163°C) for 40-45 minutes, or until the cake is golden and springs back lightly when touched.
- Cool the cake: Invert the pan immediately onto a bottle or funnel to cool completely upside down. This prevents collapse and preserves the airy structure.
- Remove and serve: Once cooled, run a knife around the edges to release the cake from the pan. Slice and serve plain or with a dusting of powdered sugar or fresh lemon glaze if desired.
Notes
- Using room temperature egg whites is crucial for maximum volume and lightness.
- Coating blueberries in flour keeps them from sinking to the bottom of the cake during baking.
- Cream of tartar stabilizes whipped egg whites to avoid collapse; vinegar or lemon juice can substitute but results may vary.
- If cake flour is unavailable, create a homemade substitute with all-purpose flour and cornstarch as described.
- Allowing the cake to cool inverted ensures it maintains height and airiness.
- Lemon zest can be swapped for lime or orange zest for a different citrus twist.
- Fresh berries are preferred over frozen to avoid excess moisture in the batter.
