Use the parchment slings to lift the brownies straight out. Grab a sharp knife and cut them into neat squares, cleaning the blade after every slice so the pieces look tidy.

Set the pan back in the oven so the brownies can finish baking for another 15 minutes. Take it back out and tap the pan twice on the counter. Let them hang out in the pan for about an hour or at least until they're cool all the way through.

Scrape the batter into your lined pan and smooth out the top. Get them cooking for 20 minutes at 350°F. Take the pan out and hit it firmly on your counter a couple of times so any trapped air bubbles pop.

Pour the salt and flour on top of your wet mix after sifting them. Fold it all together with a rubber spatula, being gentle so you keep things fluffy. If you mix too much, they'll get heavy.

Take the matcha-chocolate mix and pour it right into your sugar and eggs. Mix them slowly until it's even. Drop in that vanilla and blend it just until it's all together.

Dump both sugars in a big mixing bowl. Crack in your eggs, then mix everything with an electric mixer on high for about 3-5 minutes until it gets pale and puffy, kind of like thick melted ice cream.

Toss the white chocolate chips and matcha powder in a medium bowl. Pour your warm melted butter right on top, then stir till it's smooth and the chips are melted. You shouldn't see any lumps.

Pop butter into your microwave in short bursts (1 minute at a time, maybe 1 or 2 goes) or heat it up on the stove so it's completely liquid.

Set your oven to heat up at 350°F. Spray your 8x8 pan with nonstick, then line it with parchment, letting the sides stick out for easy lifting later.
