Method
Bake the yellow sponge
- Preheat oven to 350°F and set out a 9-inch round cake pan for batter. Whisk all-purpose flour, baking powder, and salt until evenly combined.
- Beat egg yolks with granulated sugar until pale and thick, about 3 minutes. Mix in vegetable oil, water, and vanilla extract until smooth.
- Fold the flour mixture into the yolk mixture until no dry streaks remain. In a separate bowl, beat egg whites until stiff peaks form.
- Gently fold the egg whites into the batter to keep it light. Pour batter into the 9-inch round cake pan and bake for 30 minutes, until a toothpick comes out clean.
- Cool the cake completely before slicing. Aim for room temperature so the pastry cream spreads without melting.
Layer and chill
- Slice the cooled cake into two layers. Spread half the pastry cream on the bottom layer and arrange half the whole strawberries on top.
- Add the top cake layer and spread the remaining pastry cream. Arrange the remaining whole strawberries on top in a decorative pattern.
- Dust with powdered sugar right before refrigerating. Refrigerate for at least 1 hour before serving.
Notes
For clean layers and neat strawberry placement, let the sponge cool fully and refrigerate the assembled cake once assembled; it will set nicely after at least 1 hour and stays fresh in the fridge for up to 3 days. Do not freeze because the whole strawberries can weep and the pastry cream texture can break down after thawing. For an egg-allergy friendly swap, use an equal amount of store-bought egg replacer for baking (follow package directions) to reduce egg dependence while keeping the cake’s light crumb.
