- 2 teaspoons butter
- 8 large eggs, separated, at room temperature
- 1 cup sifted cake flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon pure vanilla extract
- 1/12 cups sugar plus 2 tablespoons
- 1/4 teaspoon almond extract
- 1/2 recipe Seven Minute Frosting
- 3 cups mixed berries
Preheat the oven to 350 degrees F.
Line two 9-inch round pans with parchment and grease with 2 teaspoons butter and sprinkle with 2 tablespoons of sugar, tapping out any excess sugar.
Put the egg yolks and 3/4 cups of sugar in the bowl of a standing mixer and whisk over a saucepan of simmering water until the sugar has dissolved and the mixture is warm, about 2 to 3 minutes. Remove from the heat and place on the standing mixer fitted with a wire whisk. Beat on medium-high speed until the mixture is pale yellow, thick, and has tripled in volume, about 5 minutes. Beat in the salt, vanilla and almond extract. Spoon into a large mixing bowl and set aside.
In a clean bowl, with the whisk attachment, whip the egg whites until soft peaks form. Gradually add the remaining 3/4 cups sugar and continue beating until the egg whites are shiny and just form stiff peaks.
Sift the flour and baking powder over the egg yolk mixture and fold until it is smooth. Add some of the egg whites and whisk together gently just to lighten the mixture. Fold in the remaining egg whites until just incorporated. Do not overmix the batter or the eggs will deflate and the batter won't rise.
Pour the cake batter evenly into each pan and bake until the cakes spring back when touched, about 15 to 17 minutes. Let cool for about 2 minutes. Sprinkle a piece of parchment paper with powdered sugar. Using a thin spatula or knife, loosen the edges of the cakes, then flip onto the paper. Cool completely.
Make the Seven-minute Frosting and spread half of the frosting on the bottom layer, top with half of the berries, top with the second layer, add the remaining frosting and berries.
Alternately, the cakes can be served plain with a dusting of powdered sugar, fresh fruit or whipped cream. The cake can also be covered and stored for a few days, or it can be frozen.
