Mastering the Classic Sponge Cake
A reliable sponge cake is the foundation for countless desserts. Once you understand the physical limits of the egg foam, you can adapt the flavorings and fillings to suit any occasion.
Temperature is your strongest tool.
Eggs whip to a higher volume when they are at room temperature. Ensure your mixing bowl is completely clean and free of grease, as any residual fat will collapse the foam.

What goes in.
- 4 largeeggs, room temperature
- 1 cupgranulated sugar
- 1 cupall-purpose flour, sifted twice
- 1 tspvanilla extract
- pinchkosher salt
Building the structure
When lifting the whisk, the batter should fall back into the bowl in a thick, continuous ribbon that sits on the surface for several seconds before dissolving.
The method.
Prepare the pan
Grease the base of the cake pan and line it with parchment paper. Dust the sides lightly with flour, tapping out the excess.
Whip the eggs
Combine eggs, sugar, and salt in the mixer. Whisk on medium-high speed for 8-10 minutes. The mixture must triple in volume and turn pale yellow.
Fold in the flour
Remove the bowl from the mixer. Sift one-third of the flour over the eggs. Using a wide silicone spatula, cut down the center and sweep around the edges to fold the flour in. Repeat until all flour is incorporated, moving deliberately to avoid deflating the foam.
Bake
Pour the batter into the pan, smoothing the top. Bake at 350°F (175°C) for 25-30 minutes. The cake is done when the top springs back when lightly touched and the edges begin to pull away from the pan.
Other turns to take.
Lemon Zest Sponge
Fold in the finely grated zest of one lemon during the final stage of folding in the flour.
Chocolate Sponge
Replace two tablespoons of the flour with high-quality unsweetened cocoa powder, sifting it together with the flour.
When it doesn't go to plan.
Do not open the oven door for the first 20 minutes to prevent the cake from sinking.
Let the cake cool in the pan for 10 minutes before running a thin knife around the edge to invert it onto a wire rack.
If the cake seems dry, brush the cooled layers with a simple syrup of equal parts sugar and water.
The ones that keep coming up.
Why did my cake sink in the middle?
This usually happens if the eggs were under-whipped or if the oven door was opened while the structure was still setting.
Can I use a hand mixer?
Yes, but you will need to spend more time monitoring the ribbon stage, as it takes longer to reach the necessary volume compared to a stand mixer.
