How to Make It
Create this delightful cake with these simple steps.
Prepare the Oven
Preheat your oven to 170°C (340°F). Ensuring the right temperature will help the cake rise evenly.
Beat the Egg Whites
Whip the egg whites until soft peaks form, then gradually add sugar and continue whipping until stiff peaks are achieved. This step is crucial for a light sponge.
Mix the Egg Yolks
In a separate bowl, whisk the egg yolks with melted butter and add the sifted flour. Combine thoroughly until smooth, then gently fold in the beaten egg whites in batches.
Bake the Cake
Pour the batter into a greased cake pan and bake for about 30 minutes or until a toothpick comes out clean. Let it cool completely before removing from the pan.
Prepare the Strawberries
While the cake cools, slice the strawberries. Mix 10g of sugar with 40ml of water in a small pan, heat until dissolved, and let it cool. This syrup will enhance the strawberries’ flavor.
Whip the Cream
In a chilled bowl, whip the cream with 10g of sugar until soft peaks form. Be careful not to over-whip, as the cream should remain smooth and spreadable.
Assemble the Cake
Once the sponge is cool, slice it in half horizontally. Layer the bottom half with whipped cream, followed by sliced strawberries, and then cover with the top half. Finish by spreading whipped cream on top and garnish with remaining strawberries.
How to Store It
Fridge: Best consumed within 2 days in an airtight container.
Freezer: No, it affects the texture of the sponge.
Reheat: Not recommended; serve chilled or at room temperature.
