Vanilla Sponge Cake

Vanilla Sponge Cake
INGREDIENTS

• Unsalted butter, for pans
• 3/4 cup all-purpose flour, plus more for pans
• 3/4 cup cornstarch
• 6 large eggs, separated
• 1 1/2 teaspoons pure vanilla extract
• 3/4 cup plus 6 tablespoons sugar
• 1/4 teaspoon table salt

INSTRUCTION

Preheat the oven to 350 degrees. Butter the bottom and sides of an 11-by-17-inch rimmed baking sheet and a 9-inch-diameter round cake pan. Line the bottom of each pan with parchment paper, and butter again. Flour the pans, and set aside. In a small bowl, sift together the flour and cornstarch; set aside.

In the bowl of an electric mixer fitted with the whisk attachment, beat egg yolks, vanilla, and 3/4 cup sugar on high until thick and pale, about 3 minutes. Transfer egg-yolk mixture to a large bowl. Wash and dry the mixer bowl and the whisk attachment.

Combine the egg whites and salt in the mixer bowl, and beat on medium speed until soft peaks form, about 1 1/2 minutes. With the mixer running, slowly add the remaining 6 tablespoons sugar. Continue beating until stiff and glossy, about 1 minute.

Fold the egg-white mixture into the egg-yolk mixture. In three additions, fold the reserved flour mixture into the egg mixture. Transfer two-thirds of the batter to the baking sheet, and smooth the top with an offset spatula. Transfer remaining batter to the round cake pan; smooth the top with the spatula. Bake until light golden brown and a cake tester inserted into the center comes out clean, about 20 minutes. Transfer the pans to wire racks to cool; turn out the cakes, remove the parchment paper, and wrap in plastic wrap until ready to use.

Sponge Cake
INGREDIENTS

• 1/2 stick unsalted butter, melted and cooled, plus more for pans
• 1 1/2 cups cake flour, plus more for pans
• 9 large eggs, room temperature, separated
• 1 1/2 cups granulated sugar, divided
• 1 teaspoon pure vanilla extract
• Pinch of coarse salt
• Confectioner's sugar, for dusting

INSTRUCTION


Preheat oven to 350 degrees. Butter two 9-inch round cake pans or two 12-by-17-inch rimmed baking sheets. Line bottoms with parchment; butter parchment and flour pans, tapping out excess flour. Whisk together egg yolks and 1 cup granulated sugar in a bowl set over a saucepan of simmering water until sugar has dissolved and mixture is warm, 3 to 4 minutes. Remove from heat and beat with a mixer on medium-high speed until pale and thick enough to form a ribbon that dissolves onto itself, 3 to 5 minutes. Beat in vanilla and salt; transfer to a large bowl.

Beat egg whites until soft peaks form. Gradually add remaining 1/2 cup granulated sugar and beat on medium-high speed until stiff, glossy peaks form, about 2 minutes. Fold one third of egg whites into yolks, then gently fold in remaining whites. Sift flour over top and gently start to fold in. When nearly all is folded in, pour melted butter down side of bowl and fold just until incorporated and smooth.

Divide batter among pans and bake until a toothpick inserted in centers comes out clean, about 25 minutes for rounds, or 15 minutes for sheets, rotating and switching racks halfway through. If baking in round pans, immediately invert cake and remove parchment, then reinvert and cool right side up. If using baking sheets and making a rolled cake, immediately invert cake onto a kitchen towel dusted with confectioner's sugar. Dust top of cake with confectioner's sugar and roll up in towel. Let cool completely, about 1 hour, before unrolling and spreading with filling.
