This recipe is designed for home bakers, using straightforward techniques and readily available ingredients to deliver a moist, tender cake that’s sure to impress.
Ingredients
- For the Cake:
- 2 ½ cups (300 g) cake flour (or all-purpose flour)
- 2 ½ teaspoons baking powder
- ½ teaspoon salt
- 3 tablespoons (15 g) matcha powder (culinary grade)
- ¾ cup (170 g) unsalted butter, softened
- 1 ½ cups (300 g) granulated sugar
- 3 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1 cup (240 ml) whole milk, at room temperature
- For the Buttercream:
- 1 cup (226 g) unsalted butter, softened
- 3 cups (360 g) powdered sugar, sifted
- 2 tablespoons (10 g) matcha powder (culinary grade)
- 2 tablespoons (30 ml) heavy cream (or milk)
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions
- Preheat and prep: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch (23 cm) round cake pans, or line the bottoms with parchment paper.
- Mix dry ingredients: In a medium bowl, whisk together the cake flour, baking powder, salt, and matcha powder. Set aside.
- Cream butter and sugar: In a large bowl, beat the softened butter and sugar with an electric mixer on medium speed until light and fluffy, about 3–4 minutes. Scrape down the sides as needed.
- Add eggs and vanilla: Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
- Alternate dry and wet: With the mixer on low speed, add the dry ingredients in three additions, alternating with the milk in two additions, starting and ending with the dry. Mix until just combined—do not overmix.
- Divide and bake: Divide the batter evenly between the prepared pans. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden on top and spring back lightly when touched.
- Cool cakes: Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely. This is crucial—if the cakes are warm, the frosting will melt.
- Make the buttercream: While the cakes cool, beat the softened butter for the frosting in a large bowl until smooth. Add the powdered sugar, matcha powder, heavy cream, vanilla, and salt. Beat on low speed until combined, then increase to medium-high and beat for 2–3 minutes until light and fluffy. If the frosting is too thick, add a little more cream; if too thin, add more powdered sugar.
- Assemble the cake: Once the cakes are completely cool, level the tops with a serrated knife if they are domed. Place one cake layer on a serving plate. Spread about ¾ cup of buttercream evenly over the top. Place the second layer on top.
- Frost the cake: Apply a thin crumb coat (a light layer of frosting) over the entire cake. Chill for 15 minutes, then apply the remaining frosting in a smooth or decorative layer. For a clean look, use an offset spatula.
- Chill and serve: Refrigerate the cake for at least 30 minutes before slicing to allow the frosting to set. Serve chilled or at room temperature.
Tips
- Use culinary-grade matcha: Ceremonial grade is too delicate for baking and can turn bitter. Culinary grade is designed for cooking and gives a vibrant color without breaking the bank.
- Room temperature ingredients: Make sure your butter, eggs, and milk are at room temperature before starting. This helps the batter emulsify properly, resulting in a lighter cake.
- Don’t overmix: Overmixing the batter can develop gluten, making the cake tough. Mix until the flour is just incorporated—a few small lumps are fine.
- Prevent a green tint on the outside: If you want a bright green crumb, add a teaspoon of lemon juice to the batter. The acid helps preserve the chlorophyll in the matcha, preventing it from browning during baking.
Serving Suggestions
Serve this matcha birthday cake as the centerpiece of a celebration, decorated with fresh berries, edible flowers, or a dusting of extra matcha powder. It pairs beautifully with a cup of hot green tea or a glass of cold milk. For a more indulgent dessert, serve slices with a scoop of vanilla ice cream or a drizzle of white chocolate sauce.
Variations
- Matcha Chocolate Cake: Replace ¼ cup of the flour with unsweetened cocoa powder to create a matcha-chocolate marble effect.
- Lemon Matcha Cake: Add the zest of one lemon to the sugar and rub it in with your fingers before creaming. The lemon brightens the matcha flavor.
- Vegan Matcha Cake: Substitute the butter with vegan butter, the eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg), and the milk with almond or oat milk. The texture will be slightly denser but still delicious.
- Gluten-Free: Use a 1:1 gluten-free flour blend in place of the cake flour. Add 1 teaspoon of xanthan gum if your blend doesn’t include it.
Storage and Reheating
Store the frosted cake in an airtight container in the refrigerator for up to 4 days. Bring slices to room temperature before serving for the best flavor and texture. You can also freeze the unfrosted cake layers (wrapped tightly in plastic wrap and foil) for up to 3 months. Thaw overnight in the refrigerator before frosting. Frosted cake can be frozen for up to 2 months, but the texture may change slightly upon thawing.
Frequently Asked Questions
Can I use all-purpose flour instead of cake flour? Yes, you can substitute cake flour with all-purpose flour by using 2 cups minus 2 tablespoons (240 g) of all-purpose flour and adding 2 tablespoons of cornstarch. Sift together before using. The cake will be slightly denser but still tender.
Why did my cake turn brown? Matcha is sensitive to heat and can oxidize, turning brown or olive-green. To prevent this, make sure your baking powder is fresh, and avoid overbaking. Adding a small amount of lemon juice to the batter helps maintain the green color.
Can I make this cake ahead of time? Absolutely! You can bake the cake layers a day in advance and store them wrapped in plastic wrap at room temperature. The frosting can also be made ahead and refrigerated for up to 3 days—just let it soften to room temperature and re-whip before using.
How do I get clean slices? Use a sharp, thin-bladed knife and wipe it with a damp paper towel between cuts. For the cleanest slices, chill the cake in the refrigerator for at least 30 minutes before cutting.
Can I reduce the sugar? You can reduce the sugar in the cake to 1 cup (200 g) without affecting the texture much, but the frosting needs the full amount to hold its structure. If you reduce the frosting sugar, it will be softer and may not pipe well.
Is matcha safe for children? Yes, matcha is just green tea powder and is safe for children in normal food quantities. However, it does contain caffeine, so you may want to avoid serving it to very young children close to bedtime.
