Preheat oven to 350 F. Spray a square baking dish with non stick spray. Line with parchment paper.

Using a spice/coffee grinder, grind tea leaves to a powder.

Using a double boiler, melt butter and chocolate.

In a bowl, combine flour, baking powder and salt. Whisk to blend well.

In a large bowl, combine sugar, eggs and vanilla. Beat well. Add chocolate and mix until well combined.

Add flour and tea and mix until thoroughly combined.

Transfer to prepared baking pan. Bake for 50-60 minutes, until brownies have set and toothpick inserted comes out almost clean.

Cool completely before inverting the pan onto a cutting board. Peel off parchment paper. Flip over.

Slice and serve.
