What Are Protein Shakes?
If you want to increase your protein intake, drinking protein shakes is an easy way to do it.
Many people drink protein shakes after working out or when they need a filling snack.
A protein shake is made by mixing protein powder and liquid, like water or milk. This creates a thick but pourable drink.
Protein powder can come from animal or plant sources. They’re also available in different flavors, including vanilla and chocolate.
Peanut Butter Banana Protein Shake Health Benefits
Increases Hydration
Your body needs fluids throughout the day. It’s important for things like digesting food and controlling your temperature.
Oat milk, which is used in this recipe, is a source of fluids. This means drinking this protein shake can add to your hydration.
Supports Digestion
The banana in this shake is so good for digestion.
It contains fiber, a nutrient that promotes regular and comfortable bowel movements.
Decreases Oxidative Stress
Over time, high levels of oxidative stress can lead to disease.
Banana is rich in antioxidants. These compounds can fight oxidative stress and reduce the risk of disease.
Helps Muscle Growth
If you’re physically active, it’s important to get enough protein within 60 minutes after working out.
Drinking this peanut butter banana protein shake is a great choice.
Protein is needed for muscle growth and recovery. It’s also needed for maintaining muscle strength as you get older.
Supports Fullness
The ingredients in this protein shake can help reduce hunger.
Fiber, which comes from the banana, is slowly digested in the body. This promotes fullness.
Protein also increases satiety, or the feeling of fullness.

Ingredient Notes

- Oat milk
Oat milk tastes best with banana, but you can use other types of milk. Soy milk and cow’s milk are great protein-rich options. - Vanilla protein powder
The vanilla flavor is delicious with banana and peanut butter. But unflavored or chocolate protein powders also work well. - Date syrup
A natural sweetener, date syrup is made from Medjool dates. - Peanut butter
To keep it healthy, use 100% peanut butter without added salt or sugar. It should have peanuts as the only ingredient. - Banana
A ripe banana adds creaminess, thickness, and flavor. Look for a banana with yellow peel and some dark brown spots.

Optional Add-Ins
Collagen powder
If you’d rather focus on skin health, use collagen powder instead of protein powder.
Collagen is the main protein in your body. It’s essential for healthy skin and joints.
Powdered collagen is usually unflavored, so it won’t change the taste of your drink.
Extracts
For a stronger vanilla flavor, add ½ teaspoon vanilla extract.
You can also add vanilla extract if you’re using unflavored protein powder.
Seeds
To increase the protein content of your shake, add 1 or 2 tablespoons of seeds.
Chia seeds, hemp seeds, and flax seeds are great choices.
They contain plant-based protein, along with anti-inflammatory fats and antioxidants.
Add the seeds after the liquids and before the fresh banana.

Expert Tips
- Always read the label of your protein powder before adding it to the blender. You might need more than one scoop per serving.
- If you prefer icier protein shakes, add a few ice cubes after the banana.
- You can use honey, maple syrup, or a Medjool date in place of date syrup. Be sure to remove the pit and chop the date first.
- Refrigerate leftover protein shake in a jar with an air-tight lid. Drink it within 1 or 2 days.
Questions You May Have
Yes, banana is delicious in protein shakes. It also adds thickness and creaminess. Use fresh banana instead of frozen to avoid a super thick protein shake.
Use cow’s milk or soy milk to increase the protein in your shake.
Feel free to add ice cubes for an icier shake, but only use a few. Adding too much will dilute the texture and flavor.
