This Blueberry Banana Peanut Butter Smoothie is the perfect blend of creamy, fruity, and nutty goodness.
Whether you're looking for a quick breakfast or a refreshing post-workout boost, this plant-based Blueberry Banana Peanut Butter Smoothie has you covered. With just 5 simple ingredients, most of which you may already have on hand, you'll enjoy a blend of protein, fiber, and antioxidants to fuel your day.

Ripe bananas are one of those things I almost always have on hand. I make a point to buy bananas weekly, opting for bunches that are still firm and greenish. I enjoy eating them plain while they're still slightly under-ripe, but once those brown spots start appearing, it's time to repurpose them! Brown-spotted bananas may not be my favorite for eating on their own (too mushy), but they're perfect for smoothies and for baking, like in this cozy chocolate banana baked oatmeal with berries. The natural sweetness they bring is unbeatable. And here's a tip: if you find yourself with too many ripe bananas at once, simply peel and freeze them in a freezer-safe bag. That way, you'll have the perfect smoothie base ready whenever you need it!

Ingredients

- Blueberries: Frozen blueberries are the star of this smoothie. Not only do they add a refreshing, frosty texture, but they're also loaded with antioxidants and fiber. Plus, frozen berries allow you to enjoy their benefits year-round without worrying about spoilage. Research suggests that blueberries support brain health. A growing body of evidence shows that regular consumption of blueberries can improve cognitive function, particularly memory and executive function, thanks to their high flavonoid content. These compounds are linked to enhanced brain activity and a reduced risk of cognitive decline.
- Ripe Banana: Ripe bananas not only enhance the flavor of your smoothie with their natural sweetness but also contribute a smooth, creamy consistency. Their overripe state means they're packed with extra flavor and can be a great way to use up bananas that might otherwise go to waste. Plus, they add a boost of potassium and fiber to your smoothie, making it even more nutritious.
- Unsweetened Plant Milk: I love using unsweetened plant milk, especially soy milk, in this smoothie for its high protein content and creamy texture. It keeps the flavor balanced and avoids added sugars.
- Peanut Butter: Peanut butter adds a deliciously nutty flavor and creamy richness to this smoothie. For the best taste and health benefits, choose a natural peanut butter that contains only peanuts and salt, and avoid varieties with added sugars and oils.
- Ground Flaxseed: Ground flaxseed is a fantastic addition to this smoothie, providing a boost of fiber and omega-3 fatty acids. These tiny seeds are rich in nutrients that support heart health and digestion. They not only add a subtle nutty flavor but also help to thicken the smoothie, enhancing both its texture and nutritional profile.

Smoothie Substitutions and Variations
- Berries - Feel free to get creative with your smoothie by experimenting with different fruits. You can use any frozen berry blend you like, whether it's a mix of strawberries, raspberries, or blackberries. This flexibility allows you to customize the flavor and nutritional profile of your smoothie to suit your preferences!
- Plant Milk - Instead of soy milk, you can use any plant-based milk of your choice, such as almond, oat, or coconut milk. If you prefer a lighter option, you can also use water. Just keep in mind that using water will slightly alter the flavor and texture of your smoothie.
- Nut butter - Feel free to swap out peanut butter for another nut butter, like almond or cashew butter, if you prefer. For a nut-free option, you can use seed butters such as pumpkin seed butter, tahini, or sunflower seed butter. Each alternative will give the smoothie a unique twist while keeping it delicious and satisfying.
- Flaxseeds - You can swap out flaxseeds for chia seeds if you prefer, or increase the amount of nut butter for added richness.
- Protein powder - Looking for a higher protein smoothie? Add a serving of your favorite plant-based protein powder. I particularly like using vanilla protein powder in this recipe for an extra boost of protein and a hint of added flavor. Try this Berry Protein Smoothie for another easy high-protein option.
- Sweetness: Want a sweeter smoothie? Try adding a few pitted dates, a drizzle of honey, maple syrup, or a splash of agave nectar.

Smoothies taste best when consumed straight away; however, you can prepare them in advance and enjoy them when you're busy by storing them in the refrigerator or freezer. You could prep this smoothie in advance and store it in the refrigerator in a clean container for up to 2 days. If ingredients separate, you may need to shake them up or re-blend them for 15 seconds in the blender. The ground flaxseed in the smoothie helps to hold it together, maintaining a smooth consistency even after refrigeration.
