In a small saucepan, combine fresh or frozen blueberries and 1 cup of water. Cook over medium-high heat for about 5 minutes, until the blueberries burst and the mixture becomes thick and saucy.

Once your blueberry sauce has cooled slightly, stir in your choice of sweetener. Adjust the quantity for desired sweetness.

In a small bowl, whisk matcha powder with hot water until smooth and velvety.

Layer the cooled blueberry syrup at the bottom of a glass, then add ice cubes halfway up the glass. Pour in plant-based milk over the ice.

Gently pour the whisked matcha over the milk and layer it for a stunning finish.

Serve immediately, garnished with extra blueberries or mint if desired.
