Add the frozen blueberries to the blender cup, followed by the milk, protein powder, and sweetener (if using).
Blend on high until for 30-60 seconds or until smooth. Pour into a glass and enjoy immediately for the best flavor and texture.
Notes
Ingredient Substitutions
Milk Alternatives: Replace the unsweetened vanilla almond milk with your preferred dairy or plant-based milk. Any will work here!
Protein Powder: I highly recommend the vanilla whey protein powder used here for the best tasting smoothies because it lets the fresh fruit flavors shine. But yes, feel free to experiment with your favorite protein powder flavors or types.
Sweetener: If you prefer a less sweet smoothie, you can omit the sweetener altogether. I usually opt for a calorie-free sugar substitute like granulated erythritol. But really any sweetener would be great here.
Recipe Variations
Chocolate Lovers: Use a scoop of chocolate protein powder and a tablespoon of sugar-free chocolate chips to transform this into a chocolate blueberry protein shake recipe (like this chocolate covered strawberry shake and this chocolate covered cherry shake, both DELICIOUS).
Peanut Butter Twist: Include a tablespoon of peanut butter for added protein and healthy fats. The smoothie will have a creamy texture with pb&j vibes.
Banana Blueberry Smoothie: Replace half the blueberries with frozen ripe banana for extra potassium and a smoother consistency.
Vanilla Berry Smoothie: Add ½ teaspoon of vanilla extract (alcohol-free or low alcohol vanilla) for a flavor boost.
Storage Info: This blueberry protein smoothie is best enjoyed immediately for the best texture.
