To get that vibrant green tint to your brownies, make sure to: - Use fresh, high quality matcha powder. They have a more vibrant colour that tends to shine through in baked goods. And remember that matcha powder that’s been sitting in your cupboard starts to lose their lustre after a while, resulting to brownies that are more brown than bright green.  - Making a 2-batter brownie also results to that lovely green colour. If you just add matcha powder to the cocoa mixture, you will taste it but the colour will get lost in all that brown. Mixing it with the cream cheese for a nice cheesecake layer ensures you get pretty green swirls all around.
