👩🍳 Step-by-Step: How to Make the Perfect Fluffy Sponge
Just follow these six steps and you’ll have a flawless, cloud-soft sponge every single time.
1️⃣ Prep Like a Pro
- Preheat oven to 355°F (180°C).
- Line the bottom of an 8-inch round cake pan with parchment. Don’t grease the sides—this helps your sponge climb and rise.
- Let your eggs come fully to room temp (trust me, it matters!).
- Sift together flour, cornstarch, and salt in a small bowl.
Good prep = stress-free baking!
2️⃣ Whip the Yolks & Sugar
- In a large bowl, beat egg yolks with 65 g sugar until pale, thick, and ribbon-like (about 3–4 min).
- Blend in vanilla.
- You want the batter to fall in thick ribbons and sit on the surface for a moment before sinking.
3️⃣ Whip the Egg Whites
- In a squeaky-clean bowl, beat egg whites until frothy.
- Gradually add the remaining 65 g sugar.
- Continue beating to stiff, glossy peaks—firm but not dry.
- This is the secret to your cake’s signature height and fluffiness.
4️⃣ Fold It All Together
- Gently fold ⅓ of the whipped whites into the yolk mixture to loosen it.
- Fold in the remaining whites with a spatula—slow and gentle!
- Sift in the dry ingredients in two batches, folding just until blended.
- 🚫 Don’t overmix, or your cake won’t rise as tall.
5️⃣ Bake to Perfection
- Pour batter into your pan and tap gently to release large air bubbles.
- Bake 25–30 minutes, until golden and a toothpick comes out clean.
- ❌ Don’t open the oven early—it could cause your cake to collapse!
6️⃣ Cool & Finish
- Let cool in the pan for 5–10 minutes.
- Run a knife around the edge and invert onto a wire rack.
- Optional: Brush with simple syrup for extra moisture.
- Now your sponge is ready to slice, layer, or decorate any way you like!
🍓 Filling & Layering Ideas
What I love most about this sponge? It’s a blank canvas for any flavor or style:
- Whipped cream + raspberry jam (or fresh strawberries)
- Lemon curd + vanilla or citrus buttercream
- Stabilized whipped cream + mixed berries
- Classic Victorian sponge: jam + whipped cream
Stable yet tender, this sponge is perfect for everything from casual brunches to wedding cakes.

Fluffy Sponge Cake Recipe (FAQ)
- Why did my sponge cake collapse after baking?
Usually from underbaking or opening the oven door too early. Make sure it’s fully baked and avoid peeking before 25 minutes. Overfolding can also deflate the batter. - Can I use all-purpose flour instead of cake flour?
You can, but the texture will be denser. For a closer match, replace 1 Tbsp of every cup of all-purpose flour with cornstarch, then sift. Cake flour is still best for a feather-light crumb. - How do I know when my egg whites are whipped enough?
Stiff peaks—when you lift the beater, the peaks stand upright, glossy, and smooth. Don’t overwhip—grainy whites won’t fold in well. - Can I make this sponge cake ahead of time?
Yes! Once cool, wrap tightly and refrigerate up to 3 days, or freeze up to 1 month. Slice into layers before freezing for easier assembly later. - What fillings work best with this sponge cake?
Anything goes! Whipped cream, berries, lemon curd, buttercream, jam—it’s also sturdy enough for layered or tiered cakes.
