I’ve made a lot of snack recipes over the years, but these Peanut Butter Protein Balls are the kind I always come back to. Not only are they soft, sweet, and chewy, but they also taste exactly like a peanut butter treat in bite-sized form. Plus, they’re totally vegan, free of refined sugar, and high in protein and fiber. Score!

Another added bonus is how easy they are to throw together. Everything gets dumped into one bowl, you roll them up, and they’re ready to go. There’s no need to heat up the oven, break out the blender, or wash multiple mixing bowls after you’re finished. They’re completely foolproof and take just 10 minutes from start to finish.

I hope you love these Peanut Butter Protein Balls as much as I do! Store a batch in your fridge so you’ve got an easy snack ready to go whenever you need it, and let me know what you think in the comments.

Peanut Butter Protein Balls ingredients

  • Rolled oats add structure and texture to the protein balls. Other types of oats, like quick oats, will also work!
  • Peanut butter binds the mixture together. Stick to creamy peanut butter and skip crunchy varieties for best results.
  • Chocolate protein powder boosts the protein content and adds lots of chocolatey goodness. I used Vega Essential Protein, but feel free to grab whatever brand you prefer. Opt for plant-based protein to keep it vegan!
  • Vanilla extract helps enhance the overall flavor of these protein balls.
  • Raisins give this recipe a little more sweetness, plus a chewy texture.
  • Maple syrup sweetens up the protein balls and helps the ingredients stick together.
  • Chia seeds contribute gut-friendly fiber, healthy fats, and a bit of extra protein.
  • Flaxseed adds fiber and creates a more cohesive texture. Make sure to use ground flaxseed rather than whole!

How to serve Peanut Butter Protein Balls

  • Enjoy as a quick post-workout snack for a protein boost.
  • Pack in your lunchbox for a satisfying sweet treat.
  • Pair with coffee or tea as an afternoon pick-me-up.
  • Crumble over yogurt or smoothie bowls to add extra crunch.
  • Serve as a healthier dessert option when you’re craving something sweet.

Substitutions & variations

  • Rolled oats – Feel free to use quick oats instead! Your protein balls will have a softer, more doughy texture, but may actually bind better and be easier to roll.
  • Peanut butter – Any type of nut or seed butter will work here, including almond butter, cashew butter, or sunflower butter.
  • Chocolate protein powder – You can also use unflavored or vanilla protein powder instead. If using either, consider adding a bit of cacao powder to keep the rich, chocolatey flavor.
  • Maple syrup – Honey and agave are both solid substitutes. Choose agave to keep the recipe vegan.
  • Raisins – If you’re not a fan of raisins, swap in mini chocolate chips, dried cranberries, or chopped dates to switch up the flavor.

Quick recipe tips

  • Adjust the texture as needed by adding a splash of plant-based milk if the mixture is too dry or a little extra oats if it feels too wet.
  • Let the mixture sit for a few minutes before rolling to give the oats, flax, and chia seeds time to absorb moisture and firm up.
  • Press firmly when shaping to help the protein balls stay together and prevent crumbling.

Make ahead & storage

These No-Bake Peanut Butter Protein Balls are amazing for meal prep! Whip up a big batch at the beginning of the week so you have an easy grab-and-go snack waiting in your fridge.

Meal prep

  • Make them ahead: Prepare and roll the protein balls in advance, then keep them chilled in the fridge until you’re ready to enjoy.
  • Double the batch: These store well, so feel free to make extras to keep on hand for busy weeks.

Storing leftovers

Freezing

  • Freeze for later: You can store the protein balls in a freezer-safe container or bag for up to 3 months.
  • Thaw and enjoy: Let them thaw in the refrigerator overnight or at room temperature for about 15-30 minutes before eating.
