Delightfully Green: The Ultimate Matcha Vanilla Cake with Irresistible Frosting
Discover a light, airy, and moist green tea cake crowned with the silkiest matcha buttercream. This Matcha Vanilla Cake is not just a dessert; it’s an experience that will both delight and surprise your senses.

While this vibrant green cake might arrive a day late for St. Patrick’s festivities, its creation wasn’t tied to any holiday. Instead, this particular Matcha Vanilla Cake holds a far more personal significance. Today marks what would have been my Dad’s 63rd birthday. Seven years have passed since his unexpected departure, but the tradition of baking a cake in his honor each year remains a cherished ritual, a sweet remembrance of a life deeply loved.
Last year, the celebration called for a lovely lemon cake – a truly gorgeous and luscious creation, perfect if you’re seeking a bright, spring-themed dessert. But this year, my heart led me to the unique, earthy elegance of matcha. If you share my fondness for the distinct taste of green tea, then this cake is an absolute must-try. It evokes the same joy I find in my beloved matcha no-churn ice cream, which remains one of my all-time favorites!
It’s a bit amusing to think of my Dad celebrating with a green tea cake. He had a sweet tooth as formidable as my own, but I suspect he might have approached this unconventional flavor with a healthy dose of skepticism. Knowing him, though, I’m certain that after just one bite, his skepticism would have melted into pure delight. His adventurous spirit, once engaged, rarely disappointed.

Even though I miss him profoundly, and his passing was undeniably tragic, my memories of Dad are overwhelmingly filled with joy and laughter. He was the kind of person whose laughter was infectious – a silent, full-bodied shaking that left him breathless, tears streaming down his face, often while trying to recount a joke he simply couldn’t get through. That vivid image of him, brimming with uncontainable mirth, is how I choose to remember him most often.
My Dad died by suicide, and as I type these words, a familiar cringe washes over me. It’s incredibly difficult to articulate, yet I feel a deep responsibility to speak about it openly. I am striving to contribute to changing the pervasive stigma surrounding mental health and suicide. The manner of his death does not, and should not, define the remarkable life he lived. He was my favorite person in the entire world, and I will continue to honor his memory and legacy in every way I can.
Thank you for taking the time to read this and for sharing a small part of my journey. It means more than words can express to connect on this deeply personal level. Now, let’s dive into the star of the show – this exquisite Matcha Vanilla Cake!

Why This Matcha Vanilla Cake is a Must-Try
This Matcha Vanilla Cake isn’t just another dessert; it’s a culinary journey that balances vibrant aesthetics with complex, yet comforting, flavors. It offers a unique twist on the classic vanilla cake, infusing it with the distinct, subtly earthy notes of high-quality matcha. The result is a cake that is visually striking, with its natural green hue, and incredibly satisfying to the palate. Each bite delivers a harmonious blend of sweet vanilla and the nuanced bitterness of green tea, making it a sophisticated choice for any occasion, from a casual afternoon tea to a special birthday celebration.
The Secret to a Perfectly Moist and Fluffy Matcha Vanilla Cake
Achieving the ideal texture for a cake is paramount, and I’m absolutely thrilled with how light, airy, and incredibly moist this matcha vanilla cake turned out. The secret lies in a carefully selected combination of ingredients, each playing a crucial role in the final tender crumb:
- Buttermilk: A staple in many of my cake recipes, buttermilk is a true game-changer. Its acidity reacts with the baking soda and baking powder, creating a beautifully tender crumb and an irresistible fluffiness that dry cakes can only dream of. I’m such a proponent of buttermilk that I almost exclusively use it for my pancakes, including these fantastic whole wheat blueberry buttermilk pancakes!
- Oil and Eggs: The combination of a neutral-flavored oil (like grapeseed or canola) and three whole, room-temperature eggs is crucial for ensuring a consistently moist texture throughout the cake. Oil contributes moisture that remains liquid at room temperature, keeping the cake tender long after baking, while eggs add richness, structure, and emulsification.
- Vanilla Bean Paste: To elevate the vanilla flavor from good to extraordinary, I wholeheartedly recommend using vanilla bean paste. This is the one I personally use and trust for its rich, potent flavor and beautiful speckles. If vanilla bean paste isn’t accessible, a good quality vanilla extract will suffice, though the flavor won’t be quite as pronounced or complex.
- Quality Matcha Powder: The quality of your matcha powder directly impacts the cake’s flavor and color. Opt for a ceremonial or culinary grade matcha that is vibrant green and has a fresh, slightly grassy aroma. Inferior matcha can result in a dull color and a bitter, less appealing taste.
By carefully selecting and combining these ingredients, you’ll create a cake base that is not only deeply flavored with matcha and vanilla but also boasts a melt-in-your-mouth moistness that will have everyone reaching for a second slice.
Crafting the Irresistible Matcha Buttercream Frosting
What truly sets this cake apart is its magnificent buttercream frosting, a perfect duality of flavors designed to complement the cake layers beautifully. I’ve found that a thoughtful approach to the frosting not only enhances the taste but also creates a stunning visual presentation.
The Perfect Frosting Balance: Vanilla and Matcha
For the buttercream, I opt for a split flavor profile: half classic vanilla and half distinct matcha. This allows for a delightful contrast in both taste and appearance. The vanilla buttercream serves as a sweet, creamy filling between the cake layers, offering a familiar comfort that perfectly bridges the matcha-infused sponge. The exterior of the cake, however, is generously coated in the vibrant matcha buttercream, creating an eye-catching green finish that hints at the unique flavor within.
Just envisioning the smooth, rich texture and the exquisite balance of these two frostings makes me want to whip up another batch and double the recipe! It’s truly that good and adds an incredible depth to the overall cake experience.
Baking and Layering for Visual Appeal
While the recipe calls for baking the cake batter in two separate 9-inch cake pans, a little trick I employ enhances both the presentation and the frosting distribution: I carefully slice each cooled cake horizontally into two even layers. This yields a total of four beautiful cake layers. This method not only makes for a more impressive height but also allows for more generous and even application of both vanilla and matcha buttercreams, ensuring a balanced flavor in every slice. Of course, if you prefer a simpler approach, keeping it as two thick layers will still result in a delicious cake!
I hope you all had a wonderful and festive St. Patrick’s Day weekend! And if you’re still craving a touch of green, this Matcha Vanilla Cake is the perfect way to extend the celebration with a truly extraordinary treat.

Description
A light, airy, green tea cake that has the best matcha frosting! This matcha vanilla cake will delight and surprise!
Ingredients
Scale
Cake
- 2 cups all-purpose flour, sifted
- 1 tsp baking soda
- 1 1/2 tsp baking powder
- 1/2 tsp salt
- 2 tbsp matcha powder*
- 1/2 cup unsalted butter, room temperature
- 1 cup granulated sugar
- 1/2 cup oil (grapeseed, canola)
- 3 eggs, room temperature
- 1 tbsp vanilla bean paste
- 1/2 cup buttermilk
Buttercream Frosting
- 1 1/2 cups unsalted butter, room temperature
- 6 cups powdered sugar
- 1/2 cup heavy cream
- 2 tsp vanilla bean paste (or extract)
- pinch salt
- 2 tsp matcha powder
Instructions
- Preheat the oven to 350 F, grease and lightly flour two 9″ cake pans. Set aside.
- In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt and matcha powder. In the bowl of a stand mixer fitted with the paddle attachment, or using an electric mixer, combine the butter and sugar together on medium-high speed until creamed together, and smooth (about 3-4 minutes). Add the oil, and mix together for another couple of minutes. With the mixer running on low, add the eggs, one at a time, followed by the vanilla bean paste. Scrape down the mixing bowl with a rubber spatula as necessary. With the mixer still on low, add half of the flour mixture to the batter, followed by the buttermilk, then the remaining flour mixture. Mix just until there is no more flour visible.
- Pour the batter into the two pans, using a scale if necessary to ensure they’re evenly distributed. Bake the cakes until done, about 25 minutes; check to see if they’re done by inserting a toothpick in the center of the cake. If it comes out clean, remove the cakes from the oven. If not, bake for an additional couple of minutes. Cool the cakes in the pan for 5 minutes, then remove to a wire rack to cool completely before frosting.
- Prepare the buttercream. In the bowl of a stand mixer fitted with the paddle attachment or with an electric mixer, beat the butter on medium until light and fluffy. Add half of the powdered sugar, followed by half of the cream, all of the vanilla bean paste and salt. Add the remaining powdered sugar and heavy cream. Remove half of the frosting to another bowl. Add the matcha powder to the remaining frosting in the mixing bowl and mix on high until thoroughly combined.
- Assemble and frost the cake by placing one layer on a cake stand or cake circle, adding a layer of vanilla frosting, and placing the second layer on top. Use the remaining vanilla frosting to lightly coat the entire cake (this is your crumb coat). Ice and decorate the rest of the cake with the matcha frosting!
Cake will keep well at room temperature for 3-4 days. Leftovers can also be frozen in an airtight container for up to 2 months. Cake layers may also be prepared in advance and frozen for up to 2 months.
