Peanut Butter Banana Protein Balls are a perfect little snack packed with creamy peanut butter, sweet banana, and a boost of protein to keep you energized. These bite-sized treats have a chewy texture and just the right amount of natural sweetness, making them a great option for a quick pick-me-up or a pre-workout snack.
I love how easy these protein balls are to make—just mix everything together, roll them up, and they’re ready to eat or stash in the fridge for later. They save me on busy days when I need something healthy but don’t want to spend time preparing food. Plus, the combo of peanut butter and banana always feels like a cozy, comforting flavor that reminds me of my favorite childhood sandwiches.
My favorite way to enjoy these is fresh from the fridge after a workout or as a midday snack with a glass of milk or a cup of tea. They’re great for packing in lunchboxes, taking along on hikes, or keeping on hand when you need a little energy boost without a sugar crash. Honestly, once you try them, they might just become your go-to snack too!
Key Ingredients & Substitutions
Rolled oats: These bring a chewy texture and help bind everything. If you want a finer texture, you can pulse oats in a food processor. For a gluten-free option, make sure to use certified gluten-free oats.
Natural peanut butter: I like using natural peanut butter for its pure flavor and less sugar. You can swap it with almond butter or sunflower seed butter for a nut-free choice. Chunky peanut butter adds nice little nut bits.
Ripe banana: The banana adds natural sweetness and moisture. Make sure it’s ripe (brown spots are good!) for best flavor and softness. You could also try mashed avocado for creaminess but the taste will change.
Protein powder: Chocolate or vanilla flavors work well here. If dairy-free, choose a plant-based protein powder like pea or hemp. The powder adds a protein boost without changing texture too much.
Sweetener and spices: Honey or maple syrup is optional—bananas usually provide enough sweetness. A dash of cinnamon adds warmth but feel free to leave it out or add nutmeg.
How Do I Get the Right Texture for Rolling Balls?
Getting the right mix consistency matters. It should be sticky enough to hold together but not too wet to be messy.
- Start mixing the wet and dry ingredients well. If the mix is crumbly or dry, add a bit of milk or more mashed banana to moisten.
- If it feels too wet and sticky, sprinkle in more oats little by little.
- Once it’s ready, wet your hands slightly to prevent sticking while rolling the balls.
- Chill the balls in the fridge for at least 30 minutes. This firms them up and makes them easier to store and eat.
With these tips, your protein balls will hold their shape perfectly and be a tasty, healthy snack you can enjoy anytime.
Equipment You’ll Need
- Mixing bowl – I find a large bowl makes it easier to combine all ingredients thoroughly.
- Spatula or wooden spoon – helps stir everything evenly without much fuss.
- Measuring cups and spoons – for precise amounts of oats, peanut butter, and sweetener.
- Small scoop or your hands – to portion out and roll the balls easily.
- Parchment paper – keeps the balls from sticking to the tray and makes clean-up easier.
- Refrigerator – helps the balls firm up for perfect texture.
Flavor Variations & Add-Ins
- Swap chocolate protein powder for vanilla for a lighter taste, or try unflavored for a pure nut-banana flavor.
- Add mini chocolate chips or chopped nuts for extra crunch and flavor.
- Mix in dried fruit like cranberries or chopped dates for a chewy sweetness.
- Use almond or cashew butter instead of peanut butter for different nutty flavors.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 30 minutes to chill in the fridge. The quick mixing and rolling make for a simple process, and chilling helps the balls firm up so they hold their shape beautifully.
Step-by-Step Instructions:
1. Mix the Wet Ingredients:
In a large bowl, mash the ripe banana until smooth. Add the peanut butter, honey or maple syrup (if you want a bit more sweetness), and vanilla extract. Stir everything together until well combined and smooth.
2. Add the Dry Ingredients:
Now add the rolled oats, protein powder, ground cinnamon (if using), and a pinch of salt to the wet ingredients. Mix thoroughly until the mixture forms a sticky dough. If it feels too dry, add a small splash of milk or more mashed banana. If it’s too wet, sprinkle in some extra oats.
3. Shape and Chill the Balls:
Using your hands, scoop out small portions and roll them into 1 to 1.5-inch balls. Place them on a tray lined with parchment paper. If you like, drizzle some extra peanut butter over the top for a tasty finish. Put the tray in the fridge and let the balls chill for at least 30 minutes to firm up.
4. Store and Enjoy:
Keep your peanut butter banana protein balls in an airtight container in the fridge for up to one week. You can also freeze them for longer storage. These little bites make a perfect, healthy snack for any time of day!
Can I Use Frozen Banana for This Recipe?
Yes! Just make sure to thaw the banana completely and drain any excess moisture before mashing. This helps keep the mixture from getting too wet and makes rolling easier.
How Should I Store Peanut Butter Banana Protein Balls?
Store them in an airtight container in the fridge for up to one week. If you want to keep them longer, freeze the balls for up to 2 months—just thaw in the fridge before eating.
Can I Substitute the Protein Powder?
Absolutely! You can use any flavor or type of protein powder you prefer. Vanilla and chocolate work great, but unflavored or plant-based powders will also blend nicely without altering the taste too much.
What If the Mixture is Too Sticky or Dry?
If it’s too sticky, add a few more oats a little at a time. If too dry, add a small splash of milk or a bit more mashed banana until you get a sticky but manageable dough for rolling.
