Start by peeling the avocado and removing the pit. Slice the banana and measure the cocoa powder, flax meal, and spinach. Having everything ready makes the blending process quick and smooth.
Pour the plant-based milk into the blender first to help the blades move easily. Add the banana, avocado, spinach, cocoa powder, and flax meal on top of the liquid. This layering helps the ingredients blend more efficiently.
Blend everything on high speed until the mixture becomes completely smooth. If the blender struggles, pause briefly and scrape down the sides so everything mixes evenly.
Add the ice cubes and blend again until the smoothie reaches your desired thickness. If you prefer a thicker smoothie, add a few more ice cubes and blend again.
Taste the smoothie once it’s blended. If you want stronger chocolate flavor, add a little more cocoa powder and blend again.
Pour the smoothie into a tall glass and serve right away. You can also top it with a few chocolate chips for a fun and delicious finishing touch.
