- Why did the sponge collapse?
- The oven door was opened too soon (thermal shock), or you knocked the air out of the whites while mixing.
- Why is the top sticky?
- The sugar didn't dissolve completely in the whites, or the cake cooled in humidity (e.g., covered while warm).
- Can I use frozen strawberries?
- Not recommended for garnish as they release water when thawing. Use them for a sauce instead.
Strawberries and Cream Sponge Cake
The secret to a perfect sponge is air: millions of tiny bubbles trapped in egg whites expand in the oven, making the cake light as a cloud. This classic recipe uses the separated egg method, the surest way to achieve a high, spongy texture that holds up well to cream and fruit.

Instructions
1
✓
Preheat oven to 350°F (180°C). Line a baking pan with parchment paper.
Tip: Oven temperature is critical for sponge cake: too low and it won't rise, too high and it burns.
2
✓
Whip egg whites with a pinch of salt until soft peaks form, then gradually add sugar while whipping until glossy, stiff peaks form.
Tip: Sugar stabilizes the whites. If you can flip the bowl upside down without it falling out, it's ready.
3
✓
Lightly beat the egg yolks with a fork and gently fold them into the whites along with the vanilla.
Tip: Don't overmix; keep it marbled. It will homogenize with the flour.
4
✓
Sift flour and baking powder over the foam and fold in with large circular motions using a spatula.
Tip: Sifting prevents flour lumps that would remain as white spots in the baked cake.
5
✓
Spread batter into the pan and bake for 15-20 minutes. Test with a toothpick.
Tip: The sponge is done when the edges pull away from the pan and the center springs back when pressed.
6
✓
Turn onto a rack, peel off the paper, and let cool completely.
Tip: Paper is easiest to peel while warm; later it might stick.
7
✓
Cut into squares or slices. Whip the cream, pipe onto each slice, and top with a strawberry.
Tip: Wash and slice strawberries just before serving to prevent bleeding juice.
8
✓
Dust with confectioners' sugar for looks.
Tip: Sugar dissolves quickly on wet strawberries, so do this at the last second.
