A light sponge cake soaked with a strawberry-infused three-milk mixture, chilled until velvety, then topped with whipped cream and fresh sliced strawberries.
Add the strawberries and granulated sugar to a blender, then let sit until the berries look juicy and softened, about 15 to 30 minutes.
Pour in the evaporated milk and whole milk, then blend until completely smooth and pink.
Transfer to a container, stir in the heavy cream, then refrigerate so the strawberry puree can steep into the dairy, about 1 hour.
Strain the strawberry milk into a measuring cup or a bowl with a spout, pressing gently to move the liquid through while leaving seeds behind.
Mix and build the sponge cake
Heat the oven to 350 degrees F, grease a 9x13-inch pan, and set aside.
In a large bowl, whisk together the flour, baking powder, and salt.
In a stand mixer with the paddle, beat egg yolks and sugar until pale, thick, and doubled in volume (ribbon stage).
Mix in the vanilla and milk on low just until combined, then fold the yolk mixture into the flour mixture.
Wash and thoroughly dry the bowl, then whip egg whites with the whisk attachment on high to stiff peaks, about 3 to 4 minutes.
Fold the egg whites into the batter gently, stopping as soon as you no longer see white streaks.
Bake and cool
Pour the batter into the pan and bake for 18 to 20 minutes, then cool completely in the pan before soaking.
Soak, chill, and finish with topping
Use a skewer or fork to poke little holes all over the cake’s surface.
Slowly pour the strawberry milk mixture over the cake; it will look like a lot, but the sponge will absorb it.
Refrigerate for 2 to 3 hours, ideally overnight, so the milk moves evenly through the crumb.
Just before serving, whip the heavy cream with sifted powdered sugar until fluffy, then spread on top and finish with sliced strawberries.
Notes
For a silky soak, strain the strawberry milk after steeping. Cool the cake completely before soaking to avoid a mushy crumb. Chill the bowl and whisk for 10 minutes before whipping cream.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
