Grease an 8x8 baking pan and line with parchment paper.

Mix the brownie batter.

In a second medium mixing bowl, mix together the melted butter and the cocoa powder.

Whisk in the sugar and the eggs.

Whisk in the vanilla extract, baking powder, and salt.

Stir in the flour and the white chocoalte chips.

Pour 3/4 of the brownie batter into the prepared pan and smooth out evenly.

Using a spoon, dollop the matcha cheesecake batter onto the brownie batter. You don't need to completely cover the base layer of brownie, let some show through.

Using the same spoon, dot the remaining brownie batter on the top of the matcha cheesecake batter.

Using the spoon, create the swirls by placing the spoon in the top left corner of the pan and dragging it in a zig-zag pattern from one edge to another, all the way down to the bottom right corner.

Sprinkle the eyeball candies on the top, making sure they are right side up.

Bake for 20-30 minutes, or until a toothpick inserted in the center comes out mostly clean. Don't overbake!

Allow to cool in the pan for 10 minutes, or until cool to room temperature.
