Peanut Butter Banana Protein Balls are a perfect little snack that packs a punch of energy and flavor. These bite-sized treats combine creamy peanut butter, sweet ripe bananas, and a boost of protein to keep you fueled throughout the day. Their chewy texture and natural sweetness make them an easy and delightful grab-and-go option.
I love making these whenever I need a quick pick-me-up or a post-workout bite. They come together super fast, and there’s no baking involved, which is a huge bonus on busy days. Plus, the mix of peanut butter and banana always reminds me of childhood snacks but with a healthier twist that really fills me up.
My favorite way to enjoy these protein balls is straight from the fridge when they’re cool and firm. They’re great for packing in lunchboxes, taking to work, or even as a little treat during a hike. If you want to mix things up, you can roll them in a bit of shredded coconut or cocoa powder for an extra touch of flavor and texture.
Key Ingredients & Substitutions
Rolled Oats: These give the balls a chewy texture and hold everything together. If you want something gluten-free, just make sure to choose certified gluten-free oats.
Peanut Butter: Creamy peanut butter works smooth, but chunky adds a nice crunch. You can swap with almond or sunflower seed butter to change up flavors or skip nuts altogether.
Banana: Ripe bananas bring natural sweetness and moisture. If you can’t use banana, try applesauce or pumpkin puree, but the flavor will be different.
Protein Powder: Vanilla or unflavored works best here. Plant-based powders are great if you avoid dairy. Feel free to adjust the amount depending on how protein-packed you want them.
Honey or Maple Syrup: These add a little sweetness and help bind everything. You can use agave nectar or brown rice syrup in a pinch.
Mini Chocolate Chips: I love how these add small bursts of chocolate without overwhelming the flavor. Dark chocolate chips are a tasty alternative, or leave them out for a nutty, wholesome bite.
How Do You Make Sure the Protein Balls Hold Together Well?
Getting the right mix consistency is key so the balls don’t fall apart. Here’s how I do it:
- Mash the banana really well to add moisture evenly.
- Mix peanut butter and banana first until smooth, then add dry ingredients gradually.
- If the dough feels too sticky, add a little more oats. If too dry, add a tiny splash of water or more mashed banana.
- Roll gently but firmly so the balls keep their shape.
- Chill for at least 30 minutes to let them firm up — this helps them hold together perfectly.
Patience with mixing and chilling really makes a difference here. Once you get the feel of the dough, rolling is easy and fun!

Equipment You’ll Need
- Mixing bowl – I prefer a large one to mix everything easily without spilling.
- Small cookie scoop or spoon – helps me measure out consistent-sized balls quickly.
- Measuring cups and spoons – for accurate ingredient portions.
- Plastic wrap or airtight container – to store the balls in the refrigerator neatly.
- Optional: Microwave-safe bowl – if you want to warm the peanut butter or drizzle.
Flavor Variations & Add-Ins
- Swap mini chocolate chips for dried cranberries or chopped nuts for a different crunch and flavor.
- Use almond or cashew butter instead of peanut butter for a different nutty taste.
- Add a dash of cinnamon or a pinch of sea salt to enhance the flavor profile.
- Mix in shredded coconut or cocoa powder to create a richer, more indulgent snack.

Step-by-Step Instructions:
1. Mix the Banana and Peanut Butter:
In a large mixing bowl, mash the ripe banana well. Add the peanut butter and stir until the mixture is smooth and creamy. This will be the base that holds your protein balls together.
2. Add Sweetener and Vanilla:
Pour in the honey or maple syrup and add the vanilla extract. Mix everything well until all the ingredients are combined.
3. Combine Dry Ingredients:
Add the protein powder, rolled oats, and a pinch of salt to the bowl. Stir until you get a uniform mixture with no dry spots remaining.
4. Fold in Chocolate Chips:
Gently fold the mini chocolate chips into the mixture to spread them evenly without breaking them up.
5. Shape the Balls:
Using your hands or a small cookie scoop, form the mixture into small, bite-sized balls. Place them on a plate or baking sheet as you go.
6. Optional Peanut Butter Drizzle:
If you’d like, warm a little peanut butter in the microwave for about 15 seconds until it’s easy to drizzle. Drizzle over the protein balls for an extra peanut buttery touch.
7. Garnish and Chill:
Add a few extra mini chocolate chips on top of each ball. Then, place the balls in the refrigerator for at least 30 minutes to firm up.

Keep the protein balls stored in an airtight container in the fridge for up to one week. Enjoy them chilled as a quick, tasty snack anytime you want!
Can I Use Frozen Bananas for These Protein Balls?
Yes! Just make sure to thaw them completely and drain any excess liquid before mashing. This helps keep the mixture from becoming too wet and sticky.
How Long Do Peanut Butter Banana Protein Balls Last?
Stored in an airtight container in the refrigerator, they stay fresh for up to one week. You can also freeze them for up to three months—just thaw in the fridge before eating.
Can I Substitute the Protein Powder?
Absolutely! You can use any protein powder you prefer, like whey, plant-based, or collagen. Just pick one with a mild flavor so it doesn’t overpower the peanut butter and banana taste.
Is It Okay to Leave Out the Chocolate Chips?
Definitely! If you want to keep things simple or avoid chocolate, you can skip the chips or replace them with chopped nuts, dried fruit, or seeds for added texture.
