Add the chopped peaches, half of the unsweetened soy milk, and pure maple syrup to a bullet blender cup.
Blend the peach milk until smooth and creamy.
Pour the peach milk into a tall glass with ice.
Rinse out the blender cup and then add the rest of the soy milk and matcha green tea powder.
Blend the matcha mixture until smooth and creamy.
Carefully pour the matcha mixture into the peach milk mixture, then use a straw or spoon to gently stir and swirl.
Notes
Use ripe peaches for the best natural sweetness. Frozen peaches are okay if fresh ones are not in season.
Blend the matcha instead of whisking it for this recipe. Since you are already using a bullet blender, blending helps break up clumps and create a creamy matcha layer.
Use unsweetened soy milk (or any plant-based milk) to keep the latte balanced. Sweetened milk may make the drink too sugary, especially if your peaches are ripe.
Drink it right away. This iced latte tastes best fresh, cold, and creamy.
