Savor our Vertical Lemon Cake, bursting with spring-refreshing citrus flavors throughout the creamy frosting, soft cake, and smooth filling.
Preheat the oven to 400°F (200°C) and butter and line a 13x18-inch jelly roll pan.
In the same mixer bowl add the egg yolks, the remaining ½ cup (4 oz/115 g) sugar, lemon zest, juice and salt. Whip on High speed until pale and fluffy, 4 to 5 minutes. Stir the flour into the egg yolk mixture.
Starting with the short end of one strip, roll up the cake. Line up the next strip where the first strip ends and keep rolling up the cake. Repeat with the last cake strip and then, looking to see which end is flattest, carefully stand the cake on a serving plate.
