Add the frozen blueberries to the blender cup, followed by the milk.
Add the vanilla protein powder, oats, sweetener (if using), cinnamon, and a pinch of salt.
Blend 30-60 seconds, until smooth and creamy.
Pour the blueberry muffin protein shake into glass and enjoy!
Notes
Ingredient Substitutions
Blueberries: Well, it's not going to be a blueberry muffin shake without blueberries, but other frozen fruits like peach, banana, and cherry would be great here too.
Milk: Any kind of milk works here. Feel free to experiment with the different flavors that dairy milk and plant-based milks can offer. Coconut milk, creamy oat milk, and Fairlife milk are great choices!
Protein Powder: Other vanilla whey protein powders would work here, but they may have an overpowering vanilla protein shake flavor. I haven't found a vanilla plant-based protein that I can recommend taste-wise. I highly recommend the Bluebonnet whey recommended here!
Sweetener: Try maple syrup, honey, agave nectar, or medjool dates for natural sweetness.
Cinnamon: Nutmeg or pumpkin spice can be used for a different twist.
Recipe Variations
Add a tablespoon of chia seeds for a boost of fiber and protein.
Include a tablespoon of almond or peanut butter for healthy fat and added flavor.
Replace the oats with a teaspoon of vanilla extract for a lower carb shake with a smoother texture. I'd use alcohol free or low alcohol vanilla extract.
Storage InfoThis blueberry muffin smoothie is best enjoyed immediately for the best texture. It has been my experience that any blueberry protein shake tends to separate and does not store well.If you do want to make the shake in advance, I recommend storing it an airtight container in the fridge, and giving it a good shake before enjoying.Pro TipTurn this into protein ice cream! After blending, put into an ice cream maker.
