Consistency. Add more liquid to thin consistency, or more frozen mango to thicken consistency. You could also add a little bit of ice to thicken and ensure it's super cold. Adding too much ice can give it more of an icy texture and not as creamy, so I recommend only a couple cubes or 1/4 cup of crushed ice at the most.
Make it vegan. Use milk and yogurt that are plant-based! I love the brands Ripple and Not Milk for plant-based milks with a bit of protein. I also love Siggi's plant-based yogurts, but any kind will do.
High protein. Choosing high protein milk and yogurt, whether it's plant-based or not, is the best way to get natural protein in this smoothie. You can also add your favorite protein powder (vanilla or unflavored would be best) or other protein boosters such as chia seeds, flax seeds, or hemp seeds.
