How to Make White Chocolate Matcha Cake

Step 1: Make the Matcha Cake Batter

Preheat the oven to 350°F (175°C). Grease and line two 8-inch round cake pans.

In a medium bowl, whisk together flour, matcha powder, baking powder, and salt.

In a large bowl, beat the butter and sugar together until light and fluffy (about 3–4 minutes).

Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

In a separate bowl, mix milk, sour cream, and lemon juice (if using).

Add dry ingredients to the butter mixture in three parts, alternating with the milk mixture. Mix until just combined.

Divide the batter evenly between the pans and smooth the tops.

Step 2: Bake the Cakes

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.

Cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Step 3: Make White Chocolate Ganache Frosting

Place the chopped white chocolate in a heatproof bowl.

In a small saucepan, heat the cream until just simmering. Pour it over the white chocolate and let sit for 2 minutes.

Stir until smooth. Let the ganache cool for 10–15 minutes, then beat in the softened butter, vanilla, and a pinch of salt until fluffy.

Chill for 10–15 minutes if needed to reach a spreadable consistency.

Step 4: Assemble the Cake

Level the cooled cake layers if needed.

Place the first cake layer on a serving plate or cake stand. Spread a thick layer of ganache on top.

Add the second layer and frost the top and sides with the remaining ganache.

Decorate with a light dusting of matcha powder, white chocolate curls, or edible flowers.

Chef’s Notes

Matcha Quality Matters: Use culinary-grade matcha for baking. Avoid ceremonial grade, which is expensive and delicate for heat.

Don’t Overmix: Matcha can make the batter dense if overworked. Mix just until combined.

Balance the Sweetness: White chocolate is quite sweet, so the matcha’s earthiness balances it well. Adjust sugar based on personal taste.

Flavor Boost: A touch of lemon juice enhances the matcha flavor and gives the cake a fresh finish.

Storage: Store the cake in the refrigerator in an airtight container. Let it come to room temperature before serving for the best texture.

Frequently Asked Questions (FAQs)

1. Can I use white chocolate chips instead of chopped white chocolate?

Yes, white chocolate chips can be used, but they may contain stabilizers that prevent smooth melting. High-quality baking chocolate is preferred for the ganache.

2. What’s the best way to store this cake?

Store it in an airtight container in the refrigerator for up to 4 days. Let it sit at room temperature for 20–30 minutes before serving to soften the ganache.

3. Can I use plant-based alternatives for a vegan version?

Yes! Use vegan butter, almond milk, and dairy-free white chocolate. Be sure to use a plant-based sour cream or yogurt substitute as well.

4. What type of matcha should I use for baking?

Use culinary-grade matcha — it’s made specifically for mixing into baked goods and has a more robust, earthy flavor that holds up to heat.

5. Can I make this into cupcakes?

Absolutely. This recipe makes about 12–14 cupcakes. Bake at 350°F for 18–20 minutes. Top each with a swirl of white chocolate ganache and a sprinkle of matcha.
