# What You’ll 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, for decoration
17 - Fresh berries, for decoration

# Directions:

01 - Preheat the oven to 350°F. Grease and line two 4-inch round cake pans with parchment; lightly dust with flour or spray with nonstick spray.
02 - Sift together the flour, granulated sugar, baking powder, baking soda, salt and matcha powder into a medium bowl to ensure even distribution and remove lumps.
03 - In a separate bowl, whisk the whole milk, large egg, vegetable oil and vanilla until homogenous and slightly aerated.
04 - Pour the wet mixture into the dry ingredients and gently fold with a spatula until just combined; stop when no streaks of flour remain to preserve a light crumb.
05 - Divide the batter evenly between the two prepared pans, smoothing the tops with an offset spatula or the back of a spoon.
06 - Bake on the center rack for 15–20 minutes, or until a toothpick inserted in the center comes out clean and the edges pull slightly away from the pan.
07 - Allow the cakes to rest in their pans for 5 minutes, then invert onto a wire rack and cool completely before assembling to prevent the frosting from melting.
08 - Beat the softened butter until creamy. Gradually add the powdered sugar and continue beating until light and fluffy; add the milk, vanilla and a pinch of salt and beat until smooth and spreadable.
09 - Spread a layer of frosting on the bottom layer, place the second layer on top and apply a thin crumb coat over the entire mini cake; refrigerate 10 minutes to set if desired.
10 - Apply a final layer of frosting, decorate with sprinkles or berries as desired, and serve the mini cake at room temperature as a playful brunch centerpiece.

# Expert Advice:

01 -
  • It's a secret excuse to have cake for breakfast while pretending it's for someone else
  • No special tools or occasion needed—the cake always feels like its own small celebration
02 -
  • I learned the hard way: overmixing the batter makes the cake dense, not fluffy.
  • Let the cakes cool completely before frosting so the icing doesn't melt into a puddle.
03 -
  • A little extra sifting—both flour and matcha—makes for the softest cake crumb.
  • Chilling the cake layers briefly before frosting keeps loose crumbs out of your icing.
