Key Ingredients for Oatmeal Peanut Butter Protein Balls

See recipe card below for full list of measurements, ingredients, and instructions.

Old-Fashioned Rolled Oats

Oats give these protein balls their hearty, chewy texture and make them satisfyingly filling. For best results, use old-fashioned rolled oats instead of quick oats—they hold their shape better and add a nice bite. If you want a gluten-free option, be sure to choose certified gluten-free oats.

Natural Peanut Butter

Peanut butter is the star of the show, providing rich, nutty flavor and binding everything together. Opt for a natural, creamy peanut butter with just peanuts and salt for the healthiest result. Stir well before measuring if the oil has separated. If you have a peanut allergy, almond or cashew butter work beautifully, though they’ll add a slightly different flavor.

Protein Powder

Protein powder takes these bites to the next level, making them extra filling and perfect for post-workout snacking. A vanilla or chocolate-flavored powder pairs well here. You can use whey, plant-based, or collagen protein depending on dietary needs—the texture may vary slightly.

Honey or Maple Syrup

A touch of honey (or pure maple syrup) adds natural sweetness and helps hold the mixture together. Honey is classic, but maple syrup is a great vegan-friendly swap with a deliciously subtle flavor difference.

Mini Chocolate Chips

Chocolate chips are optional, but highly recommended! They add irresistible pops of sweetness and make these protein balls taste like dessert. For a healthier twist, use dark chocolate or cacao nibs, or skip them entirely if you prefer.

Instructions for Oatmeal Peanut Butter Protein Balls

See recipe card below for full list of measurements, ingredients, and instructions.

Mix the Wet Ingredients

In a large mixing bowl, add the peanut butter, honey (or maple syrup), and vanilla extract. Stir together until smooth and creamy. This step makes it easier to evenly mix in the dry ingredients.

Add the Dry Ingredients

Add the rolled oats, protein powder, salt, and mini chocolate chips to the bowl. Use a sturdy spoon or spatula to combine everything thoroughly. The mixture should be thick but slightly sticky. If it's too dry, add a splash more honey or a tiny bit of milk; if too wet, sprinkle in extra oats.

Chill the Dough

To make rolling easier, cover the bowl and pop it in the fridge for about 10 minutes. This step helps the mixture firm up so the balls hold their shape.

Roll Into Balls

Scoop out heaping tablespoonfuls of the mixture and roll between your palms to form balls, about 1 inch in diameter. Place them on a parchment-lined tray or plate as you go.

Enjoy or Store

The protein balls are ready to eat right away! For best texture, keep them chilled in the fridge. Store any extras in an airtight container.

Recipe Variations

Make It Vegan

Swap the honey for pure maple syrup, and use your favorite plant-based protein powder. Double-check your chocolate chips to ensure they're dairy-free as well.

Nut-Free Option

If you need a nut-free version, sunflower seed butter is a great alternative to peanut butter. The flavor will be slightly different, but still absolutely delicious and school-friendly.

Add Crunch or Fruit

Mix in 2-3 tablespoons of chopped nuts, seeds (like chia or flax), or dried fruit such as cranberries or raisins for fun flavor and texture twists.

Chocolate Lovers

For a chocolatey spin, use chocolate protein powder and add an extra tablespoon of cocoa powder to the mix. Double up on dark chocolate chips if you’re feeling decadent!

Boost the Fiber

Stir in a tablespoon of ground flaxseed or chia seed to add fiber and healthy fats, helping make these balls even more satisfying.

Serving Suggestions

Pair these Oatmeal Peanut Butter Protein Balls with a cup of coffee or tea for a quick breakfast on the go, or serve them as a nourishing snack alongside fresh fruit or Greek yogurt. For a pretty finishing touch, dust with a pinch of flaky sea salt or roll in shredded coconut before serving.

Storage and Reheating

Store your protein balls in an airtight container in the refrigerator for up to 1 week—they taste best chilled! For longer storage, freeze them for up to 3 months. Simply thaw at room temperature or in the fridge before enjoying. These are best enjoyed cold, but if you prefer them softer, let them sit at room temp for a few minutes before eating.
