Place all ingredients in a blender and pulse several seconds to mix. Pour into ice cube trays and freeze about 2 hours. When frozen, remove and place the matcha cubes in a blender together. Pulse several seconds until smooth and thick, adding about 1/4 to 1/2 cup extra Edensoy to desired thickness. Pour into glasses and serve with a spoon. If desired, sprinkle a tad more matcha on top of the slush for garnish.
