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.

Recipe FAQ

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.
