For the Cake
- 1 cup (8 ounces) unsalted butter, at room temperature, plus more for the pans
- 3 cups sifted cake flour plus more for the pans
- 1 ½ tablespoons baking powder
- ¼ teaspoon Kosher salt
- 1 ¾ cup granulated sugar divided
- 1 ¼ teaspoon pure vanilla extract
- 2 tablespoons poppy seeds plus more for garnish
- 1 tablespoon finely grated lemon zest
- 1 cup milk at room temperature
- 8 extra-large egg whites at room temperature
- ⅛ teaspoon cream of tartar
- 1 cup heavy cream chilled
- 1 .35 ounce packet of whipping cream stabilizer
For the Lemon Curd
- 6 extra large egg yolks
- ¾ cup granulated sugar
- 1 tablespoon finely grated lemon zest
- ½ cup freshly squeezed lemon juice
- 4 tablespoons (2 ounces) unsalted butter cut into 1/2 inch cubes
For the Seven-Minute Frosting
- 1 ¾ cup granulated sugar divided
- 2 tablespoons light corn syrup
- ¼ cup water
- 6 extra large egg whites
For the Cake
Preheat the oven to 350ºF. Line two 8-inch cake pans with parchment circles, butter, and dust the bottom and sides with flour, tapping out the excess.
In a medium bowl, sift together the flour, baking powder, and salt. In the bowl of a stand mixer fitted with the paddle attachment, cream the butter on medium speed until light and fluffy. Gradually add 1 ½ cups of the sugar and beat until fluffy, about 3 minutes. Scrape down the sides of the bowl and beat in the vanilla, poppy seeds, and lemon zest. Reduce the speed to low and add the flour mixture in two batches, alternating with the milk. Beat until thoroughly combined. Scrape down the side of the bowl and beat for 10 seconds more; set aside.
In a separate bowl, whisk the egg whites and cream of tartar on low until foamy. Increase the speed to medium-high and gradually add the remaining ¼ cup of sugar. Whisk until peaks are just stiff. Gently fold whites into cake batter in three additions; do not over mix. Divide the batter between the prepared pans and bake until golden, about 40 minutes. Transfer the pans to a wire rack to cool completely.
For the Lemon Curd
In a medium saucepan, combine the yolks, sugar, lemon zest, and juice. Cook over medium heat, stirring constantly until the mixture is thick and coats the back of a spoon, about 8-10 minutes. Press the mixture through a fine mesh sieve set over a medium bowl. Add the butter and stir until the butter is completely incorporated. Press a sheet of plastic wrap against the surface and chill until firm, about 1 ½ hours.
For the Filling
In a medium bowl, whip the heavy cream and packet of stabilizer to soft peaks. Gently fold in the chilled lemon curd, cover with plastic wrap and refrigerate until chilled and firm, at least 2 hours
To Assemble
Invert the cooled cakes from the pans and peel off the parchment. Using a serrated knife, slice each cake in half horizontally to make a total of four layers. Place one of the bottom layers on a serving plate with several small squares of parchment under the edges to make for a clean finished edge once frosted. Spread ⅓ (about 1 cup) of the filling over the surface and place another cake layer on top. Repeat with remaining filling and cake layers. Place five 10-inch wooden skewers in the cake (one in the center and four around the edge) to keep it from sliding. Loosely cover the cake with plastic wrap and refrigerate until firm, at least 2 hours.
For the Frosting
Combine 1 ½ cups sugar, corn syrup, and ¼ cup water in a small saucepan. Cook over medium heat, stirring gently until sugar is dissolved. Bring the mixture to a boil, washing down the sides with a wet pastry brush to prevent crystallization. Continue boiling until a candy thermometer registers 230ºF, about 5 minutes. Meanwhile, in the bowl of a stand mixer fitted with the whisk attachment, whisk the egg whites on medium speed until soft peaks form. Gradually beat in the remaining ¼ cup sugar. When the sugar syrup has reached 230ºF, reduce the mixer speed to low and carefully pour the syrup into the egg whites. Beat the frosting until it is cool, fluffy, and glossy, about 7 minutes. Remove the wooden skewers. Frost the top and sides of the chilled and set cake. Garnish with additional poppy seeds. Carefully remove the squares of parchment from under the cake. Slice and serve. Enjoy!
