NOTES: Culinary-grade matcha powder is available at most grocery stores. If powder has clumps, sift before adding. Not a fan of matcha tea? Try 2 teaspoons of a chai spice blend instead.
Spray a 9x13-inch baking dish with cooking spray. Melt butter in a large nonstick stockpot over medium heat. Add marshmallows, stirring until fully melted. Remove from heat; stir in matcha powder until uniform in color, then stir in cereal until fully coated. Transfer mixture to prepared baking dish; coat hands with cooking spray and press mixture into an even layer. Cool 10 minutes before cutting.
