Peel the ripe banana and cut into chunks. If using a second frozen banana, break into pieces so it blends evenly. Halve the avocado, remove the pit, and scoop out half of the flesh (about 1/2 avocado).

Place the banana chunks and avocado flesh into the blender jar.

Add the spirulina powder and fresh lemon juice directly on top of the fruit. The lemon keeps color bright and balances spirulina's earthiness.

Liquids & Texture

Pour in the cold water and almond milk. If using yogurt, add it now for extra creaminess.

If you want a thicker, colder smoothie and didn't use frozen banana, add the ice cubes listed in Optional Enhancers.

Secure the blender lid and blend on high for 45–60 seconds, or until the mixture is completely smooth and homogenous. Stop and scrape down the sides with a spatula if needed, then blend another 10–15 seconds.

Optional Enhancers & Final Seasoning

Taste the smoothie. If you prefer it sweeter, add up to 1 teaspoon of honey or maple syrup and blend briefly to incorporate.

If adding ground flaxseed or chia, sprinkle it in and pulse-blend 5–10 seconds to combine (chia will slightly thicken after a few minutes).

Adjust consistency as desired: add up to 1/4 cup more water or almond milk for a thinner pour, or a few more frozen banana pieces for thickness.

Pour into a chilled glass and serve immediately. Optionally garnish with a thin lemon wheel or a light dusting of spirulina (very small pinch) if desired.
