1
For the Cake: Adjust the oven rack to the lower-middle position and preheat to 325°F (160°C). Grease and flour a 9-inch round cake pan (at least 2 inches high) or a 9-inch springform pan, lining the bottom with parchment paper for easier removal.
2
In a mixing bowl, whisk together the flour, baking powder, salt, and 3 tablespoons of sugar until well blended. Incorporate the 2 whole eggs and reserved yolks, melted butter, water, and vanilla until the mixture is smooth.
3
In a separate clean bowl, combine the reserved egg whites. Beat them at medium-low speed for 1-2 minutes until frothy. Gradually add the remaining sugar, increase the speed to medium-high, and beat until soft peaks form, approximately 60-90 seconds.
4
Gently stir one-third of the beaten egg whites into the batter to lighten it, then fold in the remaining egg whites until no white streaks remain.
5
Pour the batter into the prepared pan and bake for 30 to 40 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for 10 minutes before inverting it onto a wire rack and peeling off the parchment. Let it cool completely, about 2 hours.
6
For the Strawberry Filling: Halve 24 of the most visually appealing strawberries and set aside. Quarter the remaining strawberries, then toss them in a medium bowl with 4-6 tablespoons of sugar. Allow them to rest for 1 hour while stirring occasionally to macerate.
7
Strain the juices from the macerated strawberries, reserving about 1/2 cup. In a food processor, pulse the macerated berries five times for 1 second each until roughly puréed, yielding about 1 1/2 cups.
8
In a small saucepan, combine the reserved strawberry juice and Kirsch; simmer over medium-high heat until the mixture is syrupy and reduced to about 3 tablespoons (about 3-5 minutes). Pour the syrup over the puréed strawberries and add a pinch of salt, tossing to combine. Set aside until the cake has cooled.
9
For the Whipped Cream: Once the cake has cooled, place cream cheese, sugar, vanilla, and salt in the bowl of a stand mixer fitted with a whisk attachment. Whisk on medium-high speed until the mixture is light and fluffy, about 1-2 minutes, scraping down the sides as necessary.
10
Reduce the mixer speed to low and gradually add the heavy cream in a slow, steady stream. Once incorporated, increase to medium-high speed and beat until stiff peaks form, about 2-2 1/2 minutes more, scraping down the bowl occasionally. You should have roughly 4 1/2 cups of whipped cream.
11
To Assemble the Cake: Use a large serrated knife to slice the cooled cake into three even layers. Place the bottom layer on a cardboard round or cake plate. Create a ring of 20 strawberry halves, cut sides down, around the edge of the cake.
12
Pour half of the puréed berry mixture (about 3/4 cup) into the center of the cake layer, spreading it to cover the exposed areas. Gently spread about one-third of the whipped cream (approximately 1 1/2 cups) over the berry layer, leaving a 1/2-inch border from the edge.
13
Top with the middle layer of cake, pressing down gently to level the whipped cream. Repeat the process with the remaining strawberry halves, berry mixture, and half of the remaining whipped cream before placing the final layer of cake on top.
14
Spread the remaining whipped cream over the top of the cake and decorate with the reserved strawberry halves. Serve immediately or chill for up to 4 hours before serving.
