Method
Bake the yellow sponge
- Preheat the oven to 350°F. Line a sheet pan and place a 9-inch round cake pan nearby for quick setup.
- Whisk together all-purpose flour, baking powder, and salt until evenly distributed. The mixture should look uniform with no visible lumps.
- Beat the egg yolks with granulated sugar until pale and thick, about 3 minutes. The ribbon should fall back slowly and hold its shape briefly.
- Add vegetable oil, water, and vanilla extract to the yolk mixture. Mix just until smooth and glossy.
- Fold the flour mixture into the yolk mixture. Stop when you no longer see dry streaks to keep the batter light.
- In a separate bowl, beat the egg whites until stiff peaks form. The peaks should stand straight when you lift the whisk.
- Gently fold the beaten egg whites into the batter. Keep a light hand so the batter stays airy.
- Pour the batter into the 9-inch round cake pan. Tap once on the counter to release large air bubbles.
- Bake for 30 minutes at 350°F, until a toothpick comes out clean. The top should look lightly golden and spring back when touched.
- Cool completely before slicing. The cake must be fully cool so the layers and pastry cream don’t slide.
Layer and chill
- Slice the cake into two layers. Use a level, even cut so the stacks stay stable.
- Spread half the pastry cream on the bottom layer. The cream layer should cover evenly to the edges.
- Arrange half the whole strawberries on top of the pastry cream. Place them as jewel-like whole pieces for a decorative surface.
- Add the top cake layer on top of the strawberries. Press gently just enough to adhere.
- Spread the remaining pastry cream over the top layer. Smooth it into an even layer for clean slices.
- Arrange the remaining whole strawberries on top in a decorative pattern. Tuck them slightly into the cream so they stay put.
- Dust the cake with powdered sugar. The surface should show a light, even snowfall.
- Refrigerate the cake for at least 1 hour before serving. Chill until set so the layers hold together.
Notes
Pro tip: make sure the sponge is fully cooled before assembling; warm cake will melt the pastry cream and blur the layers. Refrigerate the assembled cake for up to 2 days for best texture; freezing is not recommended because the strawberries and pastry cream can weep and soften.
