Add all ingredients except sparkling water and ice to a blender. Blend until smooth.
Fill a 12 oz glass about halfway with ice. Add half of the strawberry mixture to the glass. Top off with sparkling water. Stir to make sure everything is combined. Repeat with the second drink and enjoy.
Notes
This makes enough for 2 mocktails. If you want to make only one mocktail just half the amount of ingredients.
