My Go-To Protein Blueberry Smoothie with Peanut Butter
When it comes to quick & easy breakfasts, it’s hard to beat a quick and easy smoothie recipe! And this light, creamy and refreshing blueberry peanut butter smoothie is my newest obsession.
It’s blended with plenty of feel good ingredients like blueberries, peanut butter, banana, chia seeds, lemon juice and any milk of choice (I usually use almond milk!) to create a smoothie bursting with berry flavor.
The vanilla protein powder is optional but gives this smoothie lots of staying power to help carry you through whatever the day brings. I enjoy this smoothie as-is, but the base recipe is so versatile that it lends itself to any number of fun variations.
Robyn’s Testing Notes for Peanut Butter Blueberry Smoothie
Blueberries: The blueberries are the star ingredient in this smoothie! I tested with fresh & frozen blueberries and both work great in this recipe.
Frozen banana: You can also use fresh banana in place of frozen banana in this recipe, but add a handful of ice if needed in this case.
Milk of choice: I used unsweetened almond milk for this smoothie but you can use any milk you like. To keep this vegan, paleo and dairy free, be sure to use a non-dairy milk.
Chia seeds: Ground flax seeds are an easy substitution for chia seeds in this recipe.
Unsweetened peanut butter: I like unsweetened peanut butter in this smoothie but you can use any other type of nut butter (like almond butter) that you like in its place. For a nut-free option, be sure to use sunflower seed butter.
Lemon juice: The lemon juice really helps to brighten and lift all the flavors, and I don’t recommend skipping it.
Vanilla protein powder: You can use any protein powder you like the taste of. To keep this recipe paleo friendly, be sure to use a grain-free and dairy-free protein powder. To keep this recipe vegan friendly, be sure to choose a vegan protein powder.
