Measure out 2 tsp matcha powder and 2 oz of water at room temperature (cold water is fine as well) into a mason jar.
Cap the jar and shake thoroughly to obtain a thick and even mix or use a milk frother
Uncap the bottle and add 7 oz of milk with 1-2 Tbsp of simple syrup or honey (to taste - add more or less depending on your sweetness level)
Cap the jar again and gently shake to mix well.
Pour the latte mix over a cup of ice and enjoy!
