Warm the milk gently in a saucepan over a medium heat until just steaming, stirring from time to time to keep it smooth and prevent a skin from forming. Remove from the heat and add the finely chopped white chocolate, stirring steadily until it melts into a glossy, seamless mixture.

Sift in the matcha along with the honey, then whisk with a little energy until fully incorporated—smooth, vibrant, and free from any clumps. Continue whisking briefly, or use a handheld frother, to introduce a light, airy foam.

Pour into your favourite cups, filling them generously, and finish with a few toasted marshmallows if you like—soft, golden, and gently melting into the surface.
