In a microwave safe cup, melt the white and dark chocolate separately in the microwave in 30 second intervals until fully melted.
Add the matcha into the white chocolate and stir thoroughly.
Working quickly to avoid the chocolate hardening, place small blobs of each type of chocolate intermixed on a cookie sheet covered in wax paper or aluminum foil. Make sure the blobs of chocolate touch.
Using a fork or toothpick, swirl together the two colors of chocolate to make any design you want.
Add sprinkles on top and set in the fridge for approx. 30 minutes until fully hardened.
Carefully peel the paper off of the chocolate and break or cut into pieces. Enjoy!
