In a blender, combine the heaping 2 cups of blueberries and 1 cup of coconut water. Blend until smooth and well combined.
In a small saucepan, combine the blueberry-coconut mixture with 1 cup of lemon juice and 4 tablespoons of maple syrup. Heat over low to medium heat, stirring occasionally until everything is well mixed.
Sprinkle the 1 cup of gelatin over the mixture slowly while whisking continuously. This will help prevent clumps from forming. Keep whisking until the gelatin is completely dissolved.
Once the mixture is smooth and gelatin is fully incorporated, remove the saucepan from heat. Allow it to cool slightly before pouring it into the gummy molds.
Carefully pour the mixture into your silicone molds. You can use a dropper or a small pitcher for easier pouring.
Place the filled molds in the refrigerator and let them set for at least 2-3 hours, or until firm.
Once the gummies are set, gently remove them from the molds. Store them in an airtight container in the refrigerator.
