This luscious smoothie blends sweet-tart blackberries with creamy vanilla bean for a velvety, cloud-like texture. It's a refreshing, antioxidant-rich treat perfect for breakfast or a healthy dessert.
For storage, keep in an airtight container in the refrigerator for up to 24 hours; shake well before serving. To make ahead, blend all ingredients except chia seeds and freeze in ice cube trays; blend cubes with a splash of milk when ready. For a dairy-free version, use coconut yogurt. Add a handful of spinach for a green boost without affecting the flavor.
