If there’s one thing my family knows about me, I can’t be left hungry for long. I always need a snack between meals, lest I become a raging hangry machine.

That’s where my peanut butter energy balls come in. They’re essentially a mix of my two favorite protein snacks, protein balls, and homemade protein bars. The key difference is that I used EXTRA peanut butter, adding another layer of rich, satisfying flavor layer.

Why I love this recipe

• 4 simple ingredients. All you need are oats, peanut butter, maple syrup, and protein powder. 
• No gritty texture or fake aftertaste. So long as you use a protein powder you enjoy the taste of, you won’t even notice it. 
• Quick and easy. All you need is one bowl and a plate to store them. 
• Customizable. Swap the nut butter, add all sorts of mix-ins, or use a flavored protein powder. 
• Healthy. Each protein ball is full of protein, fiber, healthy fats, and zero refined sugar. 

Ingredients needed

• Rolled oats. Also known as old fashioned oats, these are the bulk of the protein balls. I also tested instant oats and found them to be a bit too chewy. Use certified gluten-free oats if needed. 
• Protein powder. To add protein and bind the ingredients. I used vanilla plant-based protein powder, though casein protein powder will yield an even more dense energy ball. The only type of protein I don’t recommend is whey protein, as it can be difficult to work with. 
• Peanut butter. Opt for creamy peanut butter with no added sugar. If you prefer a salty-sweet combination, use salted peanut butter or add a pinch of salt. 
• Maple syrup. For sweetness and to bind the dry ingredients. Honey and agave nectar work too.

Arman’s recipe tips

• Adjust the consistency. If the protein mixture is too wet, add more protein powder or even ground flax seeds until it reaches your desired texture. If it’s too firm, add a splash of unsweetened almond milk. 

• Swap the nut butter. If you’d rather avoid peanut butter, use cashew butter or almond butter instead. 
• Nut-free. To make a nut-free recipe, use sunflower seed butter or tahini. 
• Mix-ins. Try mini chocolate chips, shredded coconut, chia seeds, or raisins. 

Storage instructions

To store: Place the energy bites in an airtight container and store them in the fridge for up to one month. 

To freeze: Freeze the energy bites in a freezer-safe bag for up to 6 months.
