Prep your fruit. If you can, use frozen banana and mango. Slice ripe bananas and freeze them in a bag for future smoothies. Frozen fruit makes the smoothie thick and cold without diluting it.
Add liquids first. Pour your choice of liquid into the blender.
This helps the blades catch the fruit and prevents over-blending.
Layer the solids. Add mango and banana on top of the liquid. Then add yogurt, vanilla, and a pinch of salt. Drop in any boosters you like.
Blend on low, then high. Start low to break up the chunks, then increase to high for 30–45 seconds until smooth.
If it’s too thick to blend, stop and scrape the sides, then add a splash more liquid.
Taste and adjust. If it needs more sweetness, add a bit of honey or maple. If it feels flat, another tiny pinch of salt or a squeeze of lime can make the flavors pop.
Serve immediately. Pour into a chilled glass for best texture. For a smoothie bowl, keep it extra thick and top with granola, coconut flakes, or fresh fruit.
