Mini Matcha Cake (4-inch)
Matcha has a grassy flavor with a sweet finish. It adds a unique earthy flavor to baked goods and dyes the cake a beautiful green color – no green dye needed. By pairing a matcha cake with vanilla bean buttercream, you have a perfect balance of earthy and sweet flavors.
Matcha Powder
Matcha powder is a fine green powder made by grinding down tea leaves. There’s actually two different grades of matcha powder, ceremonial and culinary grades. Ceremonial is higher quality, which is used for tea ceremonies and is better for drinking. Culinary grade is used to add to baked goods. This is the brand that I buy for baking!
Prices can range between brands, but typically matcha powder is on the expensive side. I like to buy matcha powder in small batches since it starts oxidizing once opened. It’s best to use it within the month.
If you want your matcha cake to be a vibrant green color, use fresh, unopened matcha. Expired matcha powder can turn dull in color and it can lose its flavor over time.
What Does Matcha Cake Taste Like?
Like a sweet matcha latte! (If you’re a matcha latte fan, check out my matcha latte recipe!)
The matcha cake is tender, with a delicate earthy taste. Good quality matcha shouldn’t leave a bitter taste. The cake sponges are not sweet which is why pairing it with a vanilla bean buttercream compliments it and makes it delicious!
Does Matcha Cake Have Caffine?
Yes. Matcha powder contains whole ground down tea leaves. This means you get more antioxidants, nutrients, and caffeine. Caffeine amounts vary based on the brand anywhere from 40-180g. The caffeine doesn’t “bake out” during the baking process.
Although eating a slice of matcha cake has never made me jittery (and I’m super sensitive to caffeine!).
How To Make A Matcha Cake
Make sure all of the ingredients are at room temperature. Preheat the oven to 350℉ (177℃).
I like to prepare my cake pans by tracing around the bottom of the cake pan on parchment paper, then cutout the circles. You can buy precut circles (which is a time saver, I love them and they’ll last awhile).
Make sure to spray the sides of the pans with cooking spray or use butter. Then place the parchment circle on the bottom (shown in the image above). The cakes will turn out perfect every time!
In a stand mixer with the paddle attachment or in a large bowl with a hand mixer, whisk together the flour, baking powder, sugar, matcha powder (sift if clumpy), and salt.
Add the softened butter into the dry ingredients and mix on low speed until it resembles sand. In a separate bowl, add the vegetable oil, milk, egg, and vanilla extract. Whisk until combined.
Add the wet ingredients into the dry and mix on medium-low speed until combined and smooth. Some small pieces of butter are ok.
Pour the batter into the prepared cake pans. I try to pour even amounts into each pan. For these mini matcha cakes I get 180-185g per cake pan. I like to tap the pans on a kitchen towel to remove any air bubbles.
Bake for 20 minutes or until a toothpick inserted into the center of the cake comes out clean.
Transfer the pans to a wire cooling rack. After 5 minutes, use a knife to gently release the sides of the cake for the pan. Turn out the cake using oven mitts (the pans will still be hot). Let the cakes cool completely.
Vanilla Bean Buttercream
Make sure the butter is soft!
Add the softened butter to the bowl of a stand mixer with a paddle attachment or use a hand mixer. Beat the butter on high speed for one minute.
Add 1 cup of powdered sugar and mix on low for 30 seconds. Once incorporated, add the remaining cup and mix on low speed. Scrape down the sides of the bowl with a spatula.
Add the salt, vanilla bean paste, and whipping cream. Whip everything on medium speed for two minutes. Then, change the speed to low and mix for 5 minutes. If the buttercream is too stiff, add 1 tbsp of additional whipping cream and mix on low.
To test if the buttercream is ready, dip a spatula into the frosting. Pull it out and look for slight curl at the top. If the frosting stands up straight, add about 1 tsp of heavy whipping cream and mix until you get a slight curl.
I also have a faux swiss meringue matcha buttercream recipe that isn’t too sweet and has a nice smooth and pillowy texture!
Decorate
If you want to pipe a design with lots of swirls and borders, double the buttercream recipe on the recipe card below.
Once the cakes have cooled, level the tops with a serrated knife. Chill cake layers in the freezer for 5 minutes to avoid crumbs.
Add buttercream between the layers and frost the sides. Using an offset spatula will help!
Optional: Add buttercream swirls! I used a Wilton 1M tip for the largest swirls, an Ateco 22 tip for the medium stars, and a Wilton 16 tip for the mini stars. Dust with more matcha powder to finish the cake! I like to use this mini fine mesh strainer for my cake and when making matcha lattes 🙂
Store
The cake is good up to 3 days when covered in an airtight container at room temperature.
You can freeze the cake for up to 2 months in an airtight container or wrap the cake completely in plastic wrap.
You can freeze cake layers by wrapping each individual cake layer in plastic wrap while still warm. Then, put the wrapped matcha cake layers in a freezer bag and place in the freezer in a spot where it won’t get crushed.
When you need the cake layers, take them out and let them thaw for about 20 minutes.

Vanilla Bean Buttercream
- ½ cup unsalted butter, room temperature (113g or 1 stick)

Instructions
Matcha Cake
- Make sure all the ingredients are at room temperature. Preheat the oven to 350℉ (177℃). Butter or spray the sides of the cake pans with cooking spray. Cutout parchment circles and place into the pans for easier cake release.
- In a stand mixer with the paddle attachment or in a large bowl with a hand mixer, whisk together the flour, baking powder, sugar, matcha powder (sift if clumpy), and salt. Add the softened butter into the dry ingredients and mix on low speed until it resembles wet sand.
- In a separate bowl, add the vegetable oil, milk, egg, and vanilla extract. Whisk until combined.
- Add the wet ingredients into the dry and mix on medium-low speed until combined and smooth.
- Pour the batter into the prepared cake pans (180-185g per cake pan). Bake for 20 minutes or until a toothpick inserted into the center of the cake comes out clean. Bang against a kitchen towel to release air bubbles.
- Transfer the pans to a wire cooling rack. After 5 minutes, use a knife to gently release the sides of the cake for the pan. Turn out the cake using oven mitts (the pans will still be hot). Let the cakes cool completely.
Vanilla Bean Buttercream
- Add the softened butter to the bowl of a stand mixer with a paddle attachment or use a hand mixer. Beat the butter on high speed for one minute.
- Add 1 cup of powdered sugar and mix on low for 30 seconds. Once incorporated, add the remaining cup and mix on low speed. Scrape down the sides of the bowl with a rubber spatula.
- Add the salt, vanilla bean paste, and whipping cream. Whip everything on medium speed for two minutes. Then, change the speed to low and mix for 5 minutes. If the buttercream is too stiff, add 1 tsp of additional whipping cream at a time and mix on low.
Decorate
- Once the cakes have cooled, level the tops with a serrated knife. Tip: Chill cake layers in the freezer for 5 minutes to avoid crumbs.
- Add buttercream between the layers and frost the sides.
- Optional: Add buttercream swirls to the top of the cake and lightly dust with more matcha powder.
Notes
- Matcha Powder: I use this matcha powder in my matcha cakes. To get a vibrant green color, always use fresh matcha. Expired matcha dulls in color and flavor. Buy in small quantities to avoid this.
- Tools: Electric mixers whip up buttercreams to a smooth and creamy texture. A stand mixer with a paddle attachment is very helpful, or a handheld mixer with whisk attachments.
- Vanilla Bean Buttercream: This recipe makes about 2 cups of frosting and is adapted from my easy American buttercream recipe. If you want enough buttercream to make lots of extra piping designs, double the recipe.
- Substitutes: Use pure vanilla extract if you don’t have vanilla bean paste. I buy my vanilla extract in a large quality since I do a lot of baking and it’s cheaper! You can sub cake flour for all purpose flour which results in a lighter, crumbly cake texture.
- Room Temperature Ingredients: Unsalted butter, milk, and eggs will incorporate better when at room temp. Don’t skip this!
