I have three methods for you that work really well to make the most of your smoothies.
Add all ingredients except the milk to a reusable storage bag. Freeze overnight or up to 3 months. When ready to make the smoothie, add to a blender with milk and blend.
Add the ingredients to a blender. Blend well. Pour into an ice cube tray and freeze overnight. Transfer to a freezer bag, seal, and freeze for up to 3 months.
When ready to make, add 4-6 cubes to the blender with the milk and blend. Serve.
Blend ingredients in blender. Pour into containers and store in fridge for 3-5 days. Serve like drinkable yogurt or blend with ice for a classic consistency.
You can also fill reusable pouches with smoothies and freeze them to serve to a baby or toddler on a future day. Thaw for about an hour at room temperature.
