Peanut Butter Banana Protein Balls are a quick, tasty snack that combines creamy peanut butter, sweet banana, and a boost of protein all in one bite-sized treat. They’re soft, chewy, and just the right amount of sweet with a little natural energy that feels great anytime you need a pick-me-up.
I love making these when I need something easy and nutritious to grab on the go. The peanut butter gives them a rich, satisfying flavor, while the banana adds natural sweetness and moisture, so you don’t even need to add much sugar. Plus, with a good scoop of protein powder, they keep me full and energized between meals or after a workout.
My favorite way to enjoy these protein balls is chilling them for a bit in the fridge, which makes them firm up nicely and super refreshing. I also like tossing in a few chocolate chips or a sprinkle of cinnamon for an extra little hint of flavor. They’re perfect for packing in lunches, sneaking during busy afternoons, or sharing with friends when you want a healthy treat everyone will enjoy.
Key Ingredients & Substitutions
Banana: Ripe bananas add natural sweetness and moisture. Overripe bananas work best for flavor and softness. If you want a sugar-free option, try unsweetened applesauce instead.
Peanut Butter: This adds creaminess and richness. Natural peanut butter with no added sugar or salt gives a pure flavor. You can swap for almond or cashew butter if you prefer a different nut taste.
Rolled Oats: Oats provide texture and help bind the balls. If you’re gluten-free, make sure to use certified gluten-free oats.
Protein Powder: Vanilla flavor works well here, but any mild protein powder you have on hand is fine. Plant-based or whey protein both work. If you don’t have protein powder, you can add a bit more oats or nut butter to keep the mix firm.
Chocolate Chips: Mini dark chocolate chips add small bursts of sweetness and texture. Feel free to omit for a no-chocolate or lower sugar version, or use chopped nuts or dried fruit instead.
How Do You Get the Perfect Texture to Roll and Hold?
Getting the right balance of moisture and dryness is key so the mixture sticks together but isn’t too sticky.
- Mash the banana well so it blends smoothly with the peanut butter.
- Mix all ingredients thoroughly to evenly distribute moisture.
- If the mixture feels too wet, add a little more oats or protein powder.
- If too dry and crumbly, add a touch more peanut butter or a splash of milk or water.
- Chilling the balls for at least 30 minutes helps them firm up and hold their shape better.
I find pressing the mixture tightly when rolling helps create a compact, chewy texture that sticks together nicely without falling apart.
Equipment You’ll Need
- Mixing bowl – I use a large bowl to combine all the ingredients easily and thoroughly.
- Fork or potato masher – helps mash the banana smoothly so it blends well with the other ingredients.
- Measuring cups and spoons – ensure precise amounts for consistent results.
- Small scoop or spoon – makes it easier to portion out uniform-sized balls.
- Shallow plate or tray – for placing the rolled protein balls before chilling.
- Refrigerator – for chilling and firming up the balls before storage.
Flavor Variations & Add-Ins
- Different nuts or nut butters: Swap peanut butter for almond, cashew, or sunflower seed butter for variety and allergy-friendly options.
- Additional dried fruits: Mix in chopped dried cranberries, apricots, or raisins for extra sweetness and chewiness.
- Spices & extracts: Add a pinch of nutmeg, ginger, or a splash of vanilla extract to enhance flavor complexity.
- Swaps for chocolate: Replace chocolate chips with shredded coconut, chopped nuts, or seeds for a different crunch and flavor.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare, plus at least 30 minutes chilling time in the fridge to help the balls firm up. You can store them in the fridge for up to a week or freeze them if you want to keep them longer.
Step-by-Step Instructions:
1. Mash the Banana:
Start by mashing the ripe banana well in a large bowl until it becomes smooth. This will add natural sweetness and moisture to the mixture.
2. Mix Wet Ingredients:
Add the natural peanut butter and honey (or maple syrup) to the mashed banana. Stir everything together until it’s fully combined and creamy.
3. Add Dry Ingredients:
Next, mix in the rolled oats, protein powder, cinnamon (if you’re using it), and a pinch of salt. Stir well until all ingredients are evenly mixed.
4. Fold in Chocolate Chips:
Gently fold in the mini dark chocolate chips or chopped dark chocolate. These add a nice little burst of chocolate flavor in every bite.
5. Shape the Balls:
Using your hands, roll the mixture into small balls, about 1 inch in diameter. Place each on a lined plate or baking sheet as you go.
6. Optional Drizzle:
If you like, melt a little extra peanut butter and drizzle it over the top of the balls for a pretty, tasty touch.
7. Chill to Set:
Place the protein balls in the refrigerator for at least 30 minutes. This helps them firm up so they hold their shape.
8. Store and Enjoy!
Keep the balls in an airtight container in the fridge for up to a week. If you want to make them last longer, pop them in the freezer and thaw before eating.
Can I Use Frozen Bananas for This Recipe?
Yes! Just be sure to thaw the frozen banana completely and drain any excess liquid before mashing to avoid making the mixture too wet.
What Can I Substitute for Protein Powder?
If you don’t have protein powder, you can add extra oats or a tablespoon of chia seeds or ground flaxseed to help bind and boost nutrition.
How Should I Store These Protein Balls?
Store them in an airtight container in the fridge for up to one week. They also freeze well—just thaw in the fridge for a few hours before eating.
Can I Make These Nut-Free?
Absolutely! Use sunflower seed butter or tahini instead of peanut butter, and choose a nut-free protein powder to keep these allergy-friendly.
