The White Chocolate & Matcha Chocolate Cake is a masterpiece that marries the creamy sweetness of white chocolate with the earthy, slightly bitter notes of premium matcha green tea. This cake is more than just a dessert—it’s an experience. Whether you’re hosting a tea party, celebrating a birthday, or simply treating yourself to something indulgent, this cake promises elegance in every bite. With its vibrant green hue from the matcha and smooth, velvety texture from the white chocolate ganache, it’s as visually stunning as it is delicious.

The History of White Chocolate & Matcha in Baking

White chocolate, though not technically “chocolate” since it lacks cocoa solids, has been a beloved ingredient in confectionery since the early 20th century. Developed by the Swiss company Nestlé in the 1930s, it was originally created to use excess milk powder. Its rich, buttery flavor quickly gained popularity in desserts across Europe and North America.

Matcha, on the other hand, has roots tracing back over 800 years to Zen Buddhist monks in Japan. They used finely ground green tea leaves for meditation rituals, appreciating its calming yet alerting effects. Over time, matcha became central to Japanese tea ceremonies and eventually found its way into modern culinary arts, especially in desserts where its vibrant color and unique umami flavor shine.

The fusion of white chocolate and matcha is a relatively recent innovation, emerging in the 2000s as global palates began embracing bolder, more nuanced flavor combinations. Pastry chefs in Tokyo, Paris, and New York began experimenting with matcha in cakes, macarons, and mousses, often pairing it with white chocolate to balance its bitterness. Today, the White Chocolate & Matcha Chocolate Cake stands as a symbol of East-meets-West gastronomy—where tradition meets innovation.

Ingredients Breakdown: Why Each One Matters

The magic of this cake lies in the harmony of high-quality ingredients. Let’s take a closer look at what goes into each component:

All-Purpose Flour: Provides structure to the cake layers. Sifted to ensure lightness and prevent clumping.
Granulated Sugar: Sweetens the cake while helping retain moisture and contributing to browning during baking.
Cocoa Powder (Unsweetened): Adds depth and richness to the chocolate base layer, balancing the delicate matcha flavor.
Baking Soda & Baking Powder: Leavening agents that work together to create a soft, airy crumb.
Salt: Enhances all flavors and counteracts excessive sweetness.
Matcha Green Tea Powder (Ceremonial Grade): The star ingredient. High-grade matcha delivers vibrant color and authentic umami flavor without bitterness.
Eggs (Large, Room Temperature): Bind ingredients, add moisture, and help leaven the cake through air incorporation when beaten.
Butter (Unsalted, Softened): Adds richness and tenderness to the crumb. Using unsalted allows better control over salt levels.
Vegetable Oil: Keeps the cake moist and extends shelf life due to its liquid state at room temperature.
Vanilla Extract: Complements both white chocolate and matcha with warm, floral undertones.
Buttermilk: Reacts with baking soda for extra rise and imparts tanginess that balances sweetness.
Hot Water: Blooms the cocoa powder and intensifies chocolate flavor in the base layer.
Heavy Cream: Used in frosting and ganache for luxurious texture and stability when whipped.
White Chocolate (High-Quality, Chopped): Melts into a silky ganache; choose one with real cocoa butter for best results.
Milk or Dark Chocolate (Optional for Decoration): For contrast and visual appeal on top.
Edible Gold Leaf or Matcha Sprinkles (Optional): For gourmet presentation.

Step-by-Step Recipe

Ingredients

For the Cake Layers:

1 ¾ cups (220g) all-purpose flour
1 ½ cups (300g) granulated sugar
¾ cup (65g) unsweetened cocoa powder
1 ½ tsp baking powder
1 ½ tsp baking soda
1 tsp salt
¼ cup (20g) ceremonial grade matcha powder
4 large eggs, room temperature
¾ cup (170g) unsalted butter, softened
½ cup (120ml) vegetable oil
2 tsp pure vanilla extract
1 cup (240ml) buttermilk, room temperature
1 cup (240ml) hot water

For the White Chocolate Ganache Frosting:

12 oz (340g) high-quality white chocolate, finely chopped
1 ½ cups (360ml) heavy cream
2 tbsp unsalted butter, softened
1 tsp vanilla extract
Pinch of salt

For Decoration (Optional):

Extra matcha powder for dusting
Tempered dark or milk chocolate shards
Edible flowers or gold leaf
White chocolate curls

Directions

Preheat Oven & Prepare Pans: Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper. Dust lightly with cocoa powder to prevent sticking.
Mix Dry Ingredients: In a large bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, salt, and matcha powder. Whisk thoroughly to ensure even distribution of matcha and no lumps.
Cream Butter & Eggs: In a stand mixer fitted with the paddle attachment, beat softened butter on medium speed until creamy (about 1 minute). Add eggs one at a time, mixing well after each addition. Beat in oil and vanilla extract until combined.
Combine Wet & Dry Mixtures: Gradually add the dry ingredients to the wet mixture in three parts, alternating with buttermilk. Begin and end with dry ingredients. Mix on low speed just until incorporated—do not overmix.
Add Hot Water: Carefully pour in hot water. Mix on low speed until the batter is smooth and uniform. The batter will be thin—this is normal and ensures a moist cake.
Divide & Bake: Divide the batter evenly among the prepared pans. Tap pans gently on the counter to release air bubbles. Bake for 28–33 minutes, or until a toothpick inserted into the center comes out clean.
Cool Completely: Allow cakes to cool in pans for 10 minutes, then turn out onto wire racks. Remove parchment and let cool completely before frosting (at least 2 hours).
Make White Chocolate Ganache: Place chopped white chocolate in a heatproof bowl. Heat heavy cream in a saucepan over medium heat until it begins to simmer (do not boil). Pour hot cream over white chocolate. Let sit for 2 minutes, then stir gently until smooth. Stir in butter, vanilla, and salt. Cool at room temperature for 1 hour, then refrigerate for 20–30 minutes until spreadable but not stiff.
Whip Ganache: Using a hand mixer or stand mixer, whip the cooled ganache on medium-high speed for 2–3 minutes until fluffy and creamy, like buttercream.
Frost the Cake: Level the cake layers if needed. Place one layer on a cake board or plate. Spread a generous amount of ganache on top. Repeat with second layer. Place final layer upside-down for a flat surface. Apply a thin crumb coat, then chill for 20 minutes. Finish with a thick, smooth layer of ganache using an offset spatula or bench scraper for sharp edges.
Decorate: Dust lightly with additional matcha powder using a fine sieve. Add chocolate shards, curls, or edible gold accents for elegance.
Chill Before Serving: Refrigerate the cake for at least 1 hour before slicing to set the ganache and enhance flavor cohesion.

Tips for Success

Use Ceremonial Grade Matcha: Culinary grade may result in a bitter or dull taste. Ceremonial grade offers vibrant color and refined flavor.
Room Temperature Ingredients: Cold eggs or buttermilk can cause the batter to curdle or bake unevenly.
Do Not Overmix: Overmixing develops gluten, leading to a dense cake. Mix only until ingredients are incorporated.
Sift Twice: Sift dry ingredients once before measuring and again when combining to ensure fluffiness.
Even Layers: Use a kitchen scale to divide batter equally for uniform thickness and baking.
Patience with Ganache: Cooling and whipping the ganache properly ensures a light, pipeable consistency rather than a heavy glaze.
Sharp Knife for Slicing: Dip a sharp knife in hot water and wipe dry between cuts for clean slices.
Store Properly: Keep refrigerated in an airtight container for up to 5 days. Bring to room temperature before serving for optimal texture.

Variations and Customizations

This cake is highly adaptable to personal preferences and dietary needs:

Gluten-Free Version: Substitute all-purpose flour with a 1:1 gluten-free baking blend containing xanthan gum.
Dairy-Free Option: Use plant-based butter, coconut cream, and dairy-free white chocolate (check labels for cocoa butter content).
Vegan Adaptation: Replace eggs with flax eggs (4 tbsp ground flaxseed + 10 tbsp water), use almond milk mixed with lemon juice instead of buttermilk, and opt for vegan white chocolate.
Layered Flavor Profile: Add a layer of matcha mousse or white chocolate raspberry filling between cake tiers.
Mini Versions: Bake as cupcakes or use a bundt pan for a dramatic centerpiece.
Seasonal Twists: Incorporate orange zest into the ganache for a citrusy lift, or add cherry compote for a sakura-inspired theme.
Alcohol Infusion: Brush layers with matcha-infused simple syrup spiked with sake or elderflower liqueur for adult gatherings.
Nutty Crunch: Fold chopped pistachios or toasted almonds into the batter or sprinkle on top for added texture.

Frequently Asked Questions (FAQ)

Can I make this cake ahead of time?
Yes! Bake the layers up to two days in advance and store them wrapped in plastic at room temperature. The frosted cake can be refrigerated for up to 5 days or frozen (without fresh decorations) for up to 2 months. Thaw overnight in the fridge.

Why did my cake sink in the middle?
Common causes include underbaking, opening the oven too early, or overmixing the batter. Ensure your leavening agents are fresh and avoid sudden temperature changes.

Can I use regular green tea instead of matcha?
No—regular brewed green tea or loose leaves won’t provide the concentrated color or flavor needed. Only powdered matcha works for baking.

Is white chocolate really chocolate?
Technically, no. It contains cocoa butter but no cocoa solids. However, real white chocolate must contain at least 20% cocoa butter, 14% milk solids, and no more than 55% sugar to be legally labeled as such.

Can I freeze the ganache?
Yes. Freeze in an airtight container for up to 3 months. Thaw in the refrigerator, then re-whip before using.

How do I get a perfectly smooth finish?
Apply a crumb coat, chill, then use a bench scraper dipped in warm water to smooth the final layer. Rotate the turntable slowly for even pressure.

What can I pair this cake with?
Serve with jasmine tea, sparkling sake, or a light vanilla ice cream. A berry coulis adds tart contrast.
