Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a medium bowl, sift together the flour, matcha powder, baking powder, and salt. Set aside.
In a large bowl, cream the softened butter and granulated sugar together using a hand mixer or stand mixer until pale and fluffy (about 3-4 minutes).
Add eggs, one at a time, beating well after each addition. Stir in the milk and vanilla extract until well combined.
Gradually add the dry ingredients to the wet mixture, folding gently until just combined. Be careful not to overmix.
Divide the batter equally between the two prepared cake pans. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes, then carefully transfer them to a wire rack to cool completely.
In a chilled bowl, whip the heavy cream with a hand mixer until soft peaks form. Add powdered sugar and finish whipping until stiff peaks form.
Once the cakes are completely cool, place one layer on a serving cake plate. Spread half of the whipped cream on top, followed by half of the sliced strawberries.
Place the second cake layer on top. Frost the top and sides of the cake with the remaining whipped cream. Decorate the top with the remaining strawberries and mint leaves if desired.
Refrigerate for at least 30 minutes to set before slicing and serving.
Notes
Chill the cake for at least 30 minutes before serving for best results.
