⏲️ Prep
Preheat oven to 350°F (175°C).
Grease and line an 8-inch round cake pan or loaf pan.

🥄 Dry Mix
In a bowl, sift together flour, matcha, baking powder, baking soda, and salt.
Add the ground pistachios and whisk everything to combine.

🧈 Cream Butter & Sugar
In another bowl, beat butter and sugar until light and fluffy (about 2–3 minutes).
Add eggs one at a time, mixing well.

🥛 Add Wet Ingredients
Mix in vanilla, milk, and sour cream until smooth.

🌀 Combine
Gradually fold in the dry ingredients. Don’t overmix.

🔥 Bake
Pour batter into the prepared pan.
Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then transfer to a rack to cool completely.

🍵 For the Frosting:
Beat cream cheese and butter together until smooth.
Add vanilla, matcha, and powdered sugar. Beat until fluffy.
Spread on cooled cake and sprinkle with crushed pistachios.

💡 Tips:
Use high-quality matcha for vibrant green color and flavor.
You can double the recipe for a layered cake!
If you want more texture, fold in roughly chopped pistachios before baking.
