Peanut Butter Banana Protein Balls are a simple, tasty snack packed with natural energy and a hint of sweetness. These little bites combine creamy peanut butter, ripe bananas, and protein-packed ingredients that are perfect for a quick pick-me-up during the day or post-workout fuel.
I love making these because they come together quickly and don’t require baking. Mixing the ingredients feels like a fun little kitchen project, and rolling them into balls is even more satisfying. Plus, they keep well in the fridge, so I always have a few ready whenever hunger strikes.
My favorite way to enjoy these protein balls is with a tall glass of milk or alongside a cup of tea in the afternoon. They’re soft, chewy, and just the right size to snack on without feeling too heavy. If you’re looking for a wholesome treat that’s easy to make and even easier to enjoy, these protein balls are sure to hit the spot.
Key Ingredients & Substitutions
Rolled oats: These add a nice chewy texture and help bind the balls. If you want a smoother texture, you can pulse them in a food processor before mixing. For a gluten-free option, be sure to use certified gluten-free oats.
Peanut butter: Natural peanut butter works best for flavor and texture. You can swap it for almond butter or sunflower seed butter if you have a peanut allergy or prefer a different nutty taste.
Banana: Ripe bananas add natural sweetness and moisture. If bananas aren’t your favorite, unsweetened applesauce can work, but it will change the texture a bit.
Honey or maple syrup: These sweeteners help hold everything together and add a touch of sweetness. Maple syrup is a great vegan choice. You can also try agave nectar or coconut nectar.
Protein powder: Adding protein powder boosts nutrition, but it’s optional. Use your favorite flavor—vanilla or chocolate both work well. If you don’t have protein powder, you can skip it or replace it with extra oats.
How Do I Get the Right Texture for Rolling the Protein Balls?
The key to perfectly formed peanut butter banana protein balls is finding the right balance of moisture and dryness so the mixture sticks without being too sticky or crumbly.
- Start by mashing the banana really well for good moisture distribution.
- Mix all ingredients thoroughly using a spoon or your hands to fully combine.
- If the mixture feels dry and crumbly, add a little more peanut butter or a splash of plant milk, one teaspoon at a time.
- If it feels too sticky or wet to roll, sprinkle in some extra oats gradually until it firms up.
- Chill the balls for at least 30 minutes to help them hold their shape better before serving.
Rolling with slightly damp hands helps prevent sticking and makes shaping easier.
Equipment You’ll Need
- Mixing bowl – I recommend a large one to give you plenty of space to combine everything easily.
- Measuring cups and spoons – Accurate measurements help get the perfect texture and flavor.
- Silicone spatula or spoon – Makes mixing smooth and clean without sticking.
- Cookie scoop or tablespoon – Helps you portion the mixture evenly for uniform balls.
- Parchment paper or a silicone baking mat – Perfect for lining your tray so the balls don’t stick and are easy to lift off.
- Reusable container – Great for storing your protein balls in the fridge.
Flavor Variations & Add-Ins
- Chocolate chips or chopped nuts – Add into the mixture for extra crunch and flavor, especially if you love a bit of sweetness or texture.
- Dried fruits like cranberries or raisins – These give a chewy bite and natural sweetness.
- Unsweetened cocoa powder – Mix in for a richer chocolate flavor without added sugar.
- Espresso powder – A pinch can enhance the peanut butter flavor and add a coffee kick.
