Method
Bake the yellow sponge
- Preheat the oven to 350°F. Line and grease a 9-inch round cake pan so the cake bakes evenly and releases cleanly.
- Whisk together all-purpose flour, baking powder, and salt until evenly combined. This keeps the crumb light and prevents salty pockets.
- Beat egg yolks with granulated sugar until pale and thick, about 3 minutes. Look for ribboning texture that falls back onto itself.
- Add vegetable oil, water, and vanilla extract to the yolk mixture and beat just until smooth. The batter should look glossy and uniform.
- Fold the flour mixture into the yolk mixture until just combined. Stop as soon as you don’t see dry streaks to avoid a tough crumb.
- In a separate bowl, beat egg whites until stiff peaks form. The peaks should stand straight with no droop when you lift the beaters.
- Gently fold the stiff egg whites into the batter. Use a light hand so the batter stays airy.
- Pour the batter into the 9-inch round cake pan. Tap once to release large air bubbles, then smooth the top.
- Bake for 30 minutes at 350°F until a toothpick comes out clean. The center should spring back lightly when touched.
- Cool completely before slicing. Letting it cool fully prevents the sponge from tearing when layered.
Layer and chill
- Slice the cake into two layers. Use a level cut so the pastry cream spreads evenly.
- Spread half the pastry cream on the bottom layer. Cover to the edges for a stable, even stack.
- Arrange half the whole strawberries on top of the pastry cream. Place them so they’re visible and evenly spaced for a jewel-like look.
- Add the top cake layer and press very gently to seat it. Keep pressure light to avoid shifting the fruit.
- Spread the remaining pastry cream over the top layer. Smooth it to form a pale pink layer across the surface.
- Arrange the remaining whole strawberries on top in a decorative pattern. Cover gaps for an elegant, finished presentation.
- Dust the cake with powdered sugar. Use a light hand so it looks refined rather than heavy.
- Refrigerate for at least 1 hour before serving. Chilling helps the pastry cream set for cleaner slices.
Notes
Pro tip: fully cool the sponge before slicing—warm cake compresses and slides when layered with pastry cream. Refrigerate leftovers covered up to 3 days; freezing is not recommended because the whole strawberries can become watery after thawing. For a dairy-free option, use a plant-based pastry cream substitute while keeping the rest of the method the same.
