This Japanese Sponge Cake is famous for its light, airy texture and soft, jiggly feel. It’s not overly sweet, making it perfect for tea time or as a base for layered cakes.
The secret to its softness? Proper whipping and gentle folding — don’t worry, I’ll guide you step by step 👇
🧾 Ingredients
- 4 eggs (room temperature)
- ½ cup sugar
- 2 tbsp honey
- 2 tbsp milk
- ½ cup flour (sifted)
- 2 tbsp melted butter or oil
- 1 tsp vanilla (optional)
👩🍳 Step-by-Step Instructions
🔹 Step 1: Warm Eggs & Sugar
In a heatproof bowl:
- Add eggs + sugar
- Place over a bowl of warm water (double boiler method)
Whisk gently until the mixture becomes slightly warm (not hot).
👉 This helps the eggs whip better.
🔹 Step 2: Whip Until Fluffy
Using a hand mixer, beat the mixture until:
- Thick
- Pale
- Ribbon-like texture
👉 When you lift the whisk, the batter should fall like a ribbon and stay visible for a few seconds.
⚠️ This step is the key to a fluffy cake!
🔹 Step 3: Add Liquid Ingredients
Add:
- Honey
- Milk
- Melted butter (or oil)
- Vanilla
Mix gently until combined.
🔹 Step 4: Fold in Flour
Add sifted flour in batches and fold gently using a spatula.
👉 Use light folding motions
👉 Do NOT overmix (you’ll lose air)
🔹 Step 5: Prepare the Pan
Line a square or loaf pan with parchment paper (including the sides).
🔹 Step 6: Bake (Water Bath Method)
- Pour batter into the pan
- Tap lightly to remove large air bubbles
- Place pan into a larger tray filled with hot water
Bake at 150–160°C (300–320°F) for 40–50 minutes
👉 The water bath keeps the cake moist and prevents cracking.
🔹 Step 7: Cool Slowly
- Let the cake cool inside the oven slightly (door slightly open)
- Then remove and cool completely
👉 This prevents shrinking or collapsing.
🔹 Step 8: Slice & Serve
Cut into neat slices and enjoy the soft, airy texture ☁️
