Here is what you need to do to make this lip smacking Watermelon Vanilla Blossom. In a blender, add fresh or frozen watermelon pieces and (hold your breath) vanilla ice cream! That's all. Blitz till you reach a soft creamy consistency. You can add dairy free vanilla ice cream if you are vegan. Serve this drink chilled. You can even garnish it with some chopped watermelon pieces.
