Add the avocado, blueberries, almond milk, maple syrup, and vanilla extract to a blender. Tip: For a smoother texture, blend the avocado and almond milk first before adding the other ingredients.

Blend on high speed until smooth and creamy. Tip: If the mixture is too thick, add a splash more almond milk.

Add the ice cubes and blend again until the mixture is thick and frothy. Tip: For a colder shake, freeze the blueberries beforehand.

Pour into tall glasses and serve immediately. Tip: Garnish with a few extra blueberries or a drizzle of maple syrup for an extra touch of elegance.
