YOGURT SHEET CAKE

Steps:

• Preheat oven to 350°F with rack in middle. Butter a 9x13 cake pan, then line bottom with a rectangle of parchment paper and butter parchment. Dust with flour, knocking out excess.
• Sift together cake flour, baking powder, baking soda, and salt.
• Beat together butter, sugar, and vanilla with an electric mixer at high speed until pale and fluffy, 3 to 5 minutes.
• Beat in eggs, 1 at a time, at medium speed.
• At low speed, mix in flour mixture in 3 batches, alternating with yogurt, beginning and ending with flour mixture, and mixing until just combined.
• Spread batter evenly in pan and rap pan on counter several times to eliminate air bubbles.
• Bake until cake pulls away from sides of pan and a wooden pick inserted in center comes out clean, 35 to 45 minutes. Cool in pan 10 minutes, then run a knife around edge. Invert onto a rack and discard parchment. Cool completely, about 1 hour.
• When cake is cool, stir together confectioners sugar, corn syrup, cream, and vanilla until smooth.
• Put cake on a platter and spread icing on top in a thick layer, letting it run down sides. Let icing set at least 15 minutes.

YOGURT CAKE

Steps:

• Heat oven to 350 degrees and butter an 8- or 9-inch springform pan.
• Using an electric hand mixer or a standing electric mixer fitted with the whisk attachment, beat egg whites on medium-low until the mixture looks frothy, 1 to 2 minutes. Slowly start to increase the speed to medium-high. Continue to beat the egg whites until soft peaks form, about 3 minutes. Set aside.
• In a separate bowl but using the same mixer, combine yolks and sugar (no need to wash beaters after the egg white). Beat yolks on medium-high until the mixture is very pale and fluffy, about 3 minutes. Reduce speed to medium and gradually beat in flour, yogurt, lemon zest and juice, and salt until fully incorporated.
• Gently fold half of the egg whites into the yolk-yogurt mixture until only a few streaks remain. Fold in the remaining whites, scraping the bottom and sides of the bowl, until the batter is evenly mixed, light and smooth.
• Scrape the batter into prepared pan and smooth into an even layer. Bake until the top is speckled with golden brown and puffed, 40 to 55 minutes. (The 8-inch pan will take longer to bake through.) Transfer the pan to a wire rack and let cake cool before cutting. Serve warm or cold.
