Pour the milk into the cup, top with marshmallows, and add the cocoa powder.
Microwave at 500 W for about 1:30 minutes (or use the milk heating setting). Stir around and around, and enjoy!
If you mix it all up, it becomes like a cappuccino!! My sister likes to mix it until just the marshmallows are nearly melted.
I used white marshmallows (100 yen at Jusco)! I suggest using 'normal' marshmallows, not fruit flavored ones etc.
Story Behind this Recipe
This was one of my experiments, and my sister's favorite so I uploaded the recipe.
Please be careful not to let the marshmallows over-expand (adjust the heating time and amount of milk as necessary). The marshmallows are sweet, so I used unsweetened cocoa powder, but you can also use sweetened cocoa powder if you prefer.
