Start by gathering all your ingredients. Cut the ripe avocado in half, remove the pit, and scoop the flesh into your blender. Peel the banana and set it aside. Measure out your frozen wild blueberries and any additional ingredients.

In your blender, combine the avocado flesh, frozen blueberries, banana, and your choice of milk. Blend on high for about 30–60 seconds until creamy and smooth.

Taste your smoothie and add maple syrup if more sweetness is desired. Blend again briefly to incorporate.

Optionally add lemon juice or zest, blend briefly for another 5–10 seconds for a refreshing finish.

Pour the smoothie into a glass and garnish with blueberries or lemon slice. Store leftovers in an airtight container in the fridge.
