Preheat your oven to 325 degrees Fahrenheit.
In a medium bowl melt together the butter and white chocolate until smooth. Whisk in sugar. Add vanilla and eggs. Whisk in the matcha powder, salt, and flour. Set aside.
For the cookie dough, in a medium bowl cream together the butter and sugars. Add vanilla and eggs. Mix in the baking soda, salt, and flour. Mix in the chocolate chips.
Add alternating scoops of the matcha brownie batter and cookie dough to a parchment lined square pan (8x8 works great).
Bake for about 20-22 mins or until the brownie is baked through and the cookie is golden brown.
Once they cool, slice into squares and enjoy!
