🌱 Are protein balls vegan?

Peanut butter protein balls (and protein bites in general) can be vegan. A lot of recipes call for honey and whey protein powder, which are both not vegan-friendly.

However, you can easily make a vegan recipe by replacing honey with agave or maple syrup and choosing a plant-based protein powder over whey. Some of our favorite brands include Vega Protein and Greens, Garden of Life, and Four Sigmatic Protein.

🛒 Ingredients & substitutions

  • Peanut butter: For the best taste and texture, use natural peanut butter. You can opt for chunky, but we typically choose smooth in our recipe. If you don’t have (or can’t have) peanut butter, try almond, cashew, or sunflower seed butter.
  • Agave: To add natural sweetness and stick the mixture together. If you don’t have agave, the next best options are maple syrup, coconut nectar, or brown rice syrup. 
  • Vanilla: Enhances the other ingredients, adding depth of flavor. We recommend pure vanilla extract, but you can also use almond extract or a few drops of orange oil for a unique flavor profile.
  • Salt: We use sea salt to bring out the sweetness in these peanut butter protein balls. If you have salted peanut butter, you can omit the additional salt.
  • Rolled oats: Old-fashioned rolled oats provide structure and chewiness. Quick oats or steel-cut oats will work in a pinch, but the best texture comes from rolled oats.
  • Protein powder: Use your favorite vegan protein powder brand! Both vanilla and chocolate work well in this recipe, but you can also use unflavored protein and add your favorite flavor essence.
  • Flaxmeal: Ground flaxseeds add texture, omega-3 fatty acids, and fiber to these no-bake protein balls. Purchase pre-ground flaxseeds, or blend your own in a spice grinder.
  • Chia seeds: Add more fiber, omega fatty acids, and a crunchy texture. You can replace chia seeds with whole flaxseeds if you don’t have any on hand.
  • Extra mix-ins: We love adding a mixture of dark chocolate chunks and chopped pecans for extra flavors and textures. Choose your favorite vegan chocolate, chopped nuts (like almonds or walnuts), or even dried fruit.

📝 How to make peanut butter protein balls

Step 1: Mix the dry ingredients

Combine the rolled oats, protein powder, ground flaxseed, chia seeds, and salt in a bowl. Whisk the dry ingredients together until well combined. It’s easiest to mix the dry ingredients first to more evenly distribute the flavors.

Step 2: Add the wet ingredients

Once the dry ingredients are stirred, add the peanut butter, agave, and vanilla extract. The mixture should be thick and hold its shape when rolled into a ball.

Make sure the peanut butter is drippy

If it’s too dry, add the rest of the agave or a little plant milk until it sticks together. If it’s too sticky, add more oats or protein powder a tablespoon at a time.

Step 3: Shape the protein bites

Gently fold in the chocolate chunks and chopped pecans last, then line a baking sheet with parchment paper or a silicone baking mat. Using a small cookie scoop or a tablespoon, roll the mixture into 1-inch balls and place them on the baking sheet.
