Blend all ice cube ingredients until texture of choice. Either smooth or somewhat chunky works great.
Divide mixture into a 12 serving ice cube tray and freeze.
To make lemonade, juice lemons until you get about ½ cup of juice. I only used 1 regular sized lemon and juiced it in my juicer.
Combine lemon juice and water in a large container.
Warm maple syrup to allow it to mix better. Pour into container with water and lemon juice and mix well. If using a dry sweetener, then warm about 1 cup of the water and mix the dry sweetener into the warm water until it dissolves.
Then pour into the large container with the rest of the water and the lemon juice. Place in refrigerator to get cold.
Once ice cubes are done, put 3 cubes into each cup, garnish with some fresh mint and pour lemonade over the ice cubes and garnish. As the ice melts, the blueberry flavor will come through.
Notes
You can also use sweetener of choice if you don’t like maple syrup. If you use a dry sweetener, you will need to warm up some of the water and then dissolve the dry sweetener into the water so it mixes better.
