Peanut Butter Banana Health Benefits
Increases Fullness
If you’re looking for a filling snack, this peanut butter banana smoothie is a great option.
Peanut butter and banana both contain fiber, an important nutrient for staying full.
Supports Digestion
Banana is one of the best foods for healthy digestion. That’s because it contains fiber, an important nutrient for comfortable bowel movements.
Fiber helps digestion by “feeding” the good bacteria in your gut.
Offers Antioxidants
Thanks to the peanut butter and banana, this smoothie is rich in antioxidants. These are compounds that protect healthy cells from damage.
Peanut butter has antioxidants called polyphenols, while banana contains vitamin C, vitamin E, and flavonoids.
Lowers High Cholesterol
Peanut butter contains healthy fats that help lower LDL (“bad”) cholesterol. This is important because high LDL cholesterol increases the risk of heart disease.
Also, banana contains soluble fiber. This type of fiber can also reduce high blood cholesterol levels.

Ingredient Notes

- Oat milk
Any kind of milk can be used, but creamy oat milk is delicious with smoothies with banana. It has a slightly nutty and sweet taste. - Vanilla extract
Good quality vanilla extract deepens the flavor and goes well with the peanut butter and banana. - Peanut butter
For the healthiest option, use a high-quality peanut butter without added sweeteners. If possible, pick a product with peanuts as the only ingredient. - Frozen banana
The banana creates a smooth and thick smoothie texture. It’s also naturally sweet. Make sure to use frozen banana since a fresh banana will make the smoothie too thin and watery.

Optional Add-Ins
Protein powder
For a more filling smoothie, add ½ to 1 scoop of protein powder or powdered collagen. These powdered add-ins will make the drink even thicker and creamier.
You can use vanilla, chocolate, or unflavored protein made with whey or plant-based ingredients.
Seeds
Chia seeds, hemp seeds, and flax seeds will add even more healthy fats and protein. Start with 1 tablespoon to ensure the seed flavor doesn’t overpower the drink.
Leafy greens
Spinach and kale are some of the healthiest smoothie add-ins. They’re high in antioxidants, vitamins, and minerals.
Add a handful after the peanut butter and before the frozen banana.

Blender Tips
Add liquids first.
The secret to a good smoothie is to load the ingredients in the right order. Start with the liquids, which are the lightest ingredients, and finish with heaviest. This is key for efficient blending.
Slowly increase the speed.
Begin on low speed, then quickly increase to high. Avoid blending on low speed for too long, which can make the motor overheat.
Push ingredients down with tamper.
To encourage a good blend, use a tamper. This is a tool that lets you move ingredients toward the blades as they move. Always use it with the lid on, which will stop the tamper from touching the blades.

Expert Tips
- Always slice bananas before freezing. Never add whole bananas to your blender since this can damage the blades.
- Choose ripe bananas with a yellow peel and some brown spots. Don’t use green bananas, which are too firm and bitter.
- If the smoothie is too thick, add a bit of oat milk and blend for 10 seconds.
- Add another tablespoon of peanut butter for a stronger nutty flavor.
- Pour leftovers in an airtight glass jar and store it in the refrigerator for 1-2 days. Drink it as soon as possible for the best flavor and texture.
