Combine the diced strawberries with the white sugar in a bowl. Let them sit for 30 minutes to macerate.
Boil water and whisk matcha powder with 2 tablespoons of water until smooth. Add the rest of the water and chill in the fridge for a few minutes.
In a cup, add a few tablespoons of macerated strawberries, then fill with lots of ice.
Pour in the half and half until the cup is two-thirds full.
Slowly add the chilled matcha on top.
Stir with a straw and enjoy your homemade Iced Strawberry Matcha Latte!
