How to Make 1) Put the eggs in a bowl, mix, then add sugar
Step 1: Prepare Your Tools and Ingredients
First things first, preheat your oven to 180°C (356°F). Grease and flour your cake pan to ensure the cake releases easily later. Have your ingredients measured out and ready—the magic is in the timing and flow of the steps, especially when you 1) put the eggs in a bowl, mix, then add sugar. This ensures your sponge gets the perfect fluttery structure.
Step 2: Whisk Egg Yolks and Sugar
Start by placing the egg yolks in a bowl and add two-thirds of your sugar. Beat them vigorously until the mixture thickens and turns pale yellow. It’s mesmerizing to watch the batter turn silky and form ribbons — that means you’re on the right track to a heavenly cake.
Step 3: Make the Meringue
In a separate clean bowl, beat the egg whites until they start foaming and double in size. Gradually add the remaining sugar in two or three batches, continuing to beat until stiff peaks form. The step 1) put the eggs in a bowl, mix, then add sugar is crucial here since it sets the stage for the meringue’s stability, which in turn creates that signature airiness.
Step 4: Fold Batter and Flour
Sift the flour carefully and fold it gently into the yolk mixture. Then incorporate one-third of the meringue with a whisk to smooth it out. Continue folding in the remaining meringue using a spatula to preserve as much air as possible.
Step 5: Add Melted Butter
Pour the melted butter into the batter and fold it in lightly. Don’t worry if the butter isn’t fully incorporated—a few swirls of butter promise a tender crumb without sacrificing fluffiness. Remember, this process is part of mastering the way to 1) put the eggs in a bowl, mix, then add sugar to keep that fluffy charm.
Step 6: Bake and Cool
Pour your batter into the prepared cake pan. Tap it gently on the bench to release any hidden air bubbles. Bake for about 25 minutes or until a skewer inserted in the center comes out clean. Once out of the oven, drop the pan a couple of times to loosen the cake, then invert it onto a rack to cool completely. This cooling technique keeps the sponge from shrinking, preserving the perfect texture shaped by your careful mixing.

Make Ahead and Storage
Storing Leftovers
Keep your cake refrigerated in an airtight container to maintain its freshness and prevent the whipped cream from absorbing other fridge odors. It’s best enjoyed within two days, as the strawberries begin to soften and the cream may lose its charm after that window.
Freezing
While this cake is delicate, you can freeze the sponge layer alone wrapped tightly in plastic wrap and foil. However, freezing the fully assembled cake is not recommended since the whipped cream and strawberries don’t thaw well, often becoming watery or losing their texture.
Reheating
If your sponge cake feels slightly stiff after refrigeration, let it come to room temperature for about 30 minutes before serving. Avoid microwaving to protect the delicate texture and the crisp freshness of the strawberries topping, the very fruit that brings this cake to life.
FAQs
Why is the step 1) Put the eggs in a bowl, mix, then add sugar so important?
This step ensures the eggs are beaten properly, allowing sugar to dissolve evenly and air to be incorporated for volume and lightness. It lays the foundation for the sponge’s signature fluffy texture.
Can I use frozen strawberries for this cake?
Fresh strawberries are best for maintaining structure and flavor. Frozen berries tend to release water when thawed, which can make the cake soggy.
What if I don’t have a sifter for flour?
While sifting helps lighten the flour and remove lumps, you can use a fine-mesh sieve or whisk the flour vigorously to aerate it before folding into the batter.
Is it possible to make this cake without separating the eggs?
You can try the alternative method mentioned in the recipe notes, which involves beating whole eggs over a water bath, but the classic separated egg method is preferred for the best light sponge.
How do I know when the meringue is ready?
The meringue is ready when it forms firm peaks that hold their shape when you lift the whisk. This stability is key for a successful fold that maintains the airy texture of the cake.
