Preheat oven to 350°F (175°C). Grease and line an 8x8-inch baking pan with parchment paper.

Melt the butter (either in the microwave or stovetop).

In a bowl, combine white chocolate chips and matcha powder. Pour melted butter over it and stir until smooth and lump-free.

In a large mixing bowl, add granulated and brown sugar. Beat in eggs with an electric mixer for 3–5 minutes until thick and pale.

Pour in the matcha-white chocolate mixture and mix gently. Stir in the vanilla extract.

Sift in flour and salt, then gently fold with a spatula until just combined. Don’t overmix.

Pour batter into the prepared pan. Bake for 20 minutes, then remove and drop the pan 2–3 times on the counter (this helps remove air pockets).

Return to oven and bake for another 15 minutes. Once baked, drop the pan again 2 more times and cool for 1 hour.
