Hot chocolate doesn't have to be dark and decadent. This rich and creamy white chocolate version has tropical notes thanks to the coconut milk, plus a boost of caffeine and bold green color from matcha powder.
3 ounces white chocolate chips (about 1/2 cup) or white chocolate, chopped
1 (13-ounce) can unsweetened coconut milk
2 1/2 teaspoons matcha (green tea powder), plus more for serving
Marshmallows (for serving)
