Prepare the Ingredients: Start by slicing the avocado and removing the seed, then scoop out the flesh. Rinse the blueberries if fresh, and peel the banana so everything is ready to go.
Add to Blender: Place the blueberries, avocado, banana, and yogurt into the blender. Pour in the milk slowly so the blades can move smoothly while blending.
Blend Until Creamy: Turn the blender on high and let it run for about 30 to 60 seconds. The mixture should turn thick, smooth, and evenly colored with no chunks left.
Adjust the Texture: Check the thickness and add more milk if it feels too dense. Add ice cubes if you want a colder and slightly thicker finish.
Taste and Sweeten: Take a quick sip and see if it needs sweetness. Add honey or dates if needed, then blend again briefly to combine.
Serve Fresh: Pour the smoothie into a glass and enjoy it right away. The creamy texture and fresh flavor feel best when served immediately.
