It is possible to make smoothie bowls in advance, but it depends on how you plan to do so. In general, I recommend making them right before eating them so that they stay fresh and cold. Here are some things you can do if you want to make your smoothie bowl in advance: Make the smoothie recipe and then pour it into a bowl. Cover the bowl with plastic wrap and put it in the fridge. Freeze the smoothie recipe in a popsicle mold or an ice cube tray. Once they are frozen, put them into a freezer-safe bag or container. Add all of the ingredients for the smoothie bowl into a blender and blend until smooth. Pour the smoothie into a bowl and refrigerate.
