Smash Cake Mini Matcha Brunch (Printable)

Light, fluffy mini matcha cake with vanilla frosting—perfect for brunch or a playful birthday smash.

# What You Need:

→ Matcha cake

01 - 3/4 cup all-purpose flour
02 - 1/2 cup granulated sugar
03 - 1/2 teaspoon baking powder
04 - 1/8 teaspoon baking soda
05 - 1/4 teaspoon fine salt
06 - 1 tablespoon culinary-grade matcha powder
07 - 1/3 cup whole milk, room temperature
08 - 1 large egg, room temperature
09 - 1/4 cup vegetable oil
10 - 1/2 teaspoon vanilla extract

→ Vanilla frosting

11 - 1/4 cup unsalted butter, softened
12 - 3/4 cup powdered sugar, sifted
13 - 1 tablespoon milk
14 - 1/2 teaspoon vanilla extract
15 - Pinch of fine salt

→ Optional toppings

16 - Sprinkles or fresh berries, for decoration (optional)

# How to Make It:

01 - Preheat oven to 350°F. Grease and line two 4-inch round cake pans with parchment.
02 - Sift together the all-purpose flour, granulated sugar, baking powder, baking soda, salt and matcha powder into a medium bowl to ensure even distribution.
03 - In a separate bowl, whisk the whole milk, egg, vegetable oil and vanilla extract until homogenous.
04 - Pour the wet mixture into the dry ingredients and fold gently with a spatula until just combined; avoid overmixing to preserve a light crumb.
05 - Divide the batter evenly between the prepared pans and smooth the surfaces with an offset spatula or back of a spoon.
06 - Bake for 15–20 minutes, or until a toothpick inserted into the centers emerges clean and the tops spring back lightly to the touch.
07 - Allow the cakes to rest in the pans for 5 minutes, then invert onto a wire rack and cool completely before assembling.
08 - Beat the softened butter until creamy, then gradually add the sifted powdered sugar. Continue beating until light and fluffy, then incorporate the milk, vanilla and a pinch of salt until smooth.
09 - Place one layer on a serving plate, spread a thin even layer of frosting, stack the second layer, and apply a thin crumb coat to the outside. Smooth the surface as desired.
10 - Decorate with sprinkles or fresh berries if using. Serve immediately as a playful brunch treat or allow to rest briefly for cleaner slices.

# Expert Tips:

01 -
  • This cake’s matcha flavor is delightfully gentle and pairs surprisingly well with creamy vanilla frosting.
  • It comes together in less than an hour, so you can bake it even on a whim for a last-minute brunch treat.
02 -
  • Don’t be tempted to skip sifting matcha and powdered sugar—the lumps are real and especially stubborn.
  • I once tried to frost the cake while it was still a little warm; let it cool completely for a dreamy finish.
03 -
  • Only frost when completely cooled—patience gives perfect swirls.
  • Let guests sprinkle or decorate the cake themselves; it adds to the celebratory mess and fun.
