There are a few things you can do to help keep your smoothie bowl from melting. First, make sure all of your ingredients are cold before blending. This will help to keep the overall temperature of the smoothie down. Secondly, add ice to your smoothie before blending it. The ice will help to keep the smoothie colder for longer. Finally, if you're not going to be eating your smoothie right away, store it in the refrigerator until you're ready to eat it.
