Add frozen blueberries, almond milk, protein powder, almond butter, Greek yogurt, and vanilla extract to a blender. Tip: For a thicker shake, use fewer ice cubes.

Blend on high speed until smooth and creamy, about 30-45 seconds. Tip: Pause and scrape down the sides if needed.

Add ice cubes and blend again until the mixture is thick and frothy. Tip: Adjust ice to achieve your preferred consistency.

Pour into tall glasses and serve immediately. Tip: Garnish with fresh blueberries or a drizzle of almond butter for extra flair.
