There’s something magical about the moment you cut into a perfectly baked matcha sponge cake. The soft green interior reveals itself, promising a delicate balance of sweet and earthy flavors that only high-quality matcha can deliver. After years of perfecting this recipe in my home kitchen, I’m excited to share my foolproof method for creating this Japanese-inspired dessert that never fails to impress guests.
What Makes This Matcha Sponge Cake Special
This isn’t your ordinary sponge cake. The addition of ceremonial-grade matcha powder transforms it into a sophisticated dessert that’s both visually stunning and complexly flavored. The cake maintains traditional Japanese lightness while incorporating modern techniques that ensure consistent results.

| Whole milk | 60ml | Warm to room temperature |
| Unsalted butter | 40g | Melted and cooled |
| Vanilla extract | 1 tsp | Optional but recommended |
| Cream of tartar | 1/4 tsp | Helps stabilize egg whites |
Kitchen Equipment You’ll Need
| Equipment | Purpose | Recommended Type |
|---|---|---|
| Stand mixer | Whipping egg whites | Any with variable speeds |
| 8-inch cake pan | Baking | Light-colored aluminum |

The Science Behind Perfect Matcha Sponge
Understanding the chemistry behind this cake has helped me achieve consistent results. The success lies in three key factors:
- Protein structure: The eggs create a protein network that traps air bubbles
- Starch gelatinization: Proper temperature control activates the flour’s starches
- Matcha dispersion: Even distribution ensures uniform color and flavor
Step-by-Step Instructions
Preparation Phase
- Preheat your oven to 325°F (165°C)
- Line your cake pan with parchment paper
- Bring all refrigerated ingredients to room temperature (68-72°F)
- Sift together cake flour and matcha powder three times
The Mixing Process
- Separate egg whites and yolks (take care not to get any yolk in the whites)
- Beat egg yolks with half the sugar until pale and tripled in volume
- Whip egg whites:
- Start on low speed
- Add cream of tartar when foamy
- Gradually add remaining sugar
- Beat to firm peaks (but not dry)
The Crucial Fold
This is where many bakers stumble. I’ve learned that folding technique makes or breaks the cake’s texture:
- Add 1/3 of whites to yolk mixture to lighten
- Fold in remaining whites in two additions
- Add sifted flour mixture in three parts
- Finally, fold in warm milk and cooled butter
Baking Process
| Time | Temperature | Visual Cues |
|---|---|---|
| 0-15 min | 325°F | Rise begins |
| 15-25 min | 325°F | Full rise achieved |
| 25-35 min | 325°F | Surface browns slightly |
| 35-40 min | Check doneness | Springs back when touched |
Troubleshooting Common Issues
| Problem | Likely Cause | Solution |
|---|---|---|
| Cake deflates | Oven door opened too soon | Wait until minute 30 to check |
| Dense texture | Overfolded batter | Count folds, max 30 strokes |
| Cracks on top | Oven too hot | Use oven thermometer to verify temp |
| Uneven color | Poor matcha distribution | Triple sift dry ingredients |
Serving Suggestions
- Dust with extra matcha powder
- Serve with fresh whipped cream and seasonal berries
- Pair with traditional Japanese green tea
- Add a dollop of sweet red bean paste
Storage Tips
| Storage Method | Duration | Notes |
|---|---|---|
| Room temperature | 2 days | Cover with cake dome |
| Refrigerated | 5 days | Wrap in plastic wrap |
| Frozen | 3 months | Double wrap and freeze |
Frequently Asked Questions
Q: Can I use regular all-purpose flour instead of cake flour?
While possible, the texture won’t be as fine. If using all-purpose flour, remove 2 tablespoons per cup and replace with cornstarch.
Q: Why did my cake shrink after baking?
Sudden temperature changes are usually the culprit. Cool the cake in its pan for 10 minutes before removing.
Q: Can I make this cake ahead for a special occasion?
Yes! Bake up to two days ahead and store properly. Add any decorations just before serving.
Q: Why is ceremonial grade matcha important?
The flavor and color are significantly better. Culinary grade can be bitter and produce a dull green color.
Q: How do I prevent my cake from being grainy?
Triple sifting is crucial. Also, ensure your sugar is completely dissolved in the egg mixture before proceeding.

Cultural Notes
The marriage of European sponge cake technique with Japanese matcha creates a unique cross-cultural dessert. In Japan, this style of cake, known as “kasutera” when made without matcha, has been enjoyed since the 16th century. The addition of matcha powder is a more recent innovation that speaks to the adaptability of traditional recipes.
