Ingredients You'll Need

Ingredients for peanut butter protein balls in glass prep bowls.

Coconut milk - I use light canned coconut milk, but full-fat coconut milk works too.
Nut or seed butter - Use natural creamy peanut butter, cashew butter, or almond butter. For a nut-free option, use tahini or sunflower seed butter.
Sweetener - Use pure maple syrup, honey, or monk fruit maple syrup.
Extract - Use a high-quality vanilla extract or vanilla bean paste. Almond extract is another option if you want a slightly different flavor.
Protein powder - Whey protein, egg white protein, or a plant-based protein blend will all work. Use either vanilla or unflavored, unsweetened protein powder.
Rolled oats - Old-fashioned rolled oats form the base of the protein balls. Use certified gluten-free oats if needed. Regular rolled oats or quick oats will also work. Use the oats dry, not cooked.
Chocolate chips - Use your favorite chocolate chips. Mini chocolate chips work best because they distribute more evenly throughout the mixture. See my tips below for choosing dark chocolate chips.
Hemp seeds - Raw hemp seeds, also called hemp hearts, add protein and healthy fats.
Ground flaxseed - Ground flaxseed adds healthy fats, protein, and fiber.
Coconut - Use unsweetened shredded coconut in the mixture, then roll the finished protein balls in extra coconut for an optional coating.

Please see the recipe card for measurements.

Tools tip: Use a #70 cookies scoop(aka disher) or pack them into these silicone molds.

Chef's tip on chocolate chips: Standard semisweet chocolate chips work perfectly well, but you can also choose chocolate chips based on your preferences for sugar, ingredients, or food allergies. There are many options including Enjoy Life Semi-Sweet Mini Chocolate Chips (free from 14 allergens), Guittard Dark Chocolate Mini Chips (with coconut sugar), and Pascha Organic 70% Cacao Baking Chips (vegan, sugar-free). Always check the package, as ingredients and allergen information can change.

Substitutions and Variations

Make protein balls many ways to fit your taste and dietary needs. Here are just a few ideas:

Chocolate protein balls: Use chocolate protein powder in place of unflavored or vanilla protein powder.
Different chocolate: Swap the mini chocolate chips for cacao nibs, chopped dark chocolate, or white chocolate chips.
Add dried fruit: Stir in finely chopped dried cranberries, cherries, raisins, or dates.
Add warm spice: Mix in ½ teaspoon of cinnamon or a pinch of pumpkin pie spice.
Coconut-free: Omit the shredded coconut and add extra rolled oats, hemp hearts, or ground flaxseed as needed to create a firm, rollable dough.
Different milk: Replace the coconut milk with almond milk, dairy milk, half-and-half, or another milk you enjoy. Add it gradually, since thinner milks may require slightly less.

How to Make Peanut Butter Protein Balls

Ingredients for peanut butter protein ball dough in a glass bowl ready for mixing.

In a medium bowl, whisk together the milk, maple, peanut butter, and vanilla, then blend in the dry.

Mix the dough well, it will be stiff. Chill for 20-30 minutes.

Chef's make-ahead tip: These protein balls are easiest to roll soon after mixing and chilling the dough when moist. If the dough is refrigerated overnight, the oats, flaxseed, coconut, and protein powder absorb some of the moisture making it more stiff or dry. Let it warm up, then work in a small amount of warm water, about 1 teaspoon at a time, until the dough is soft, slightly glossy, and easier to roll.

Tips for Perfect Protein Balls

For perfectly round and portioned protein balls, use a handy gadget called a cookie scoop (aka a disher). Pack the dough into the scooper, pump the handle to pop the dough out of the scoop, then roll in the palm of your hands. Here is a disher size chart. I also use them to make my beef, chicken, and turkey meatballs.
Wear food-safe disposable gloves: They make the sticky dough easier to roll. You can remove the gloves before rolling the balls in the final coconut coating.
Use a silicone spatula: The dough is thick and slightly sticky, so a flexible spatula works better than a wooden spoon for mixing and scraping the bowl.
Chill the dough: The dough can be sticky and soft, so refrigerate it for about 20 minutes to firm it up, making it easier to roll.
Make protein bites instead: Press the dough into a small Souper Cubes freezer tray. The small square tray holds about 1 ounce or 2 tablespoons per cavity, while the cookie dough tray holds approximately ¾ ounce or 1⅔ tablespoons. See the photo below.

Storage

Store peanut butter protein balls in an airtight container in the refrigerator. They hold their shape best when chilled and are ready to grab for a quick snack.

They keep well in the refrigerator for up to 1 week. For longer storage, freeze them in a freezer-safe container for up to 3 months. To freeze, place the balls in a single layer until firm, then transfer to a container or zip-top freezer bag.

Thaw frozen protein balls in the refrigerator, or let one sit at room temperature for a few minutes before eating. If packing them for work, school, or travel, keep them chilled with a small ice pack.

Recipe FAQs

Why are my protein balls dry or crumbly?

Protein powders, oats, flaxseed, and coconut all absorb moisture differently. If the dough feels dry, work in a small amount of warm water until it softens and holds together. Start with a teaspoon or two.

Why is my dough too sticky?

If the mixture is too soft or sticky to roll, chill it for 20-30 minutes. You can also add a spoonful of oats, ground flaxseed, or protein powder to firm it up. And when rolling, wear disposable kitchen gloves. That helps.

Can I make protein balls without peanut butter?

Yes. Use almond butter, cashew butter, sunflower seed butter, or tahini. The flavor and texture will vary slightly depending on the nut or seed butter you choose.

What kind of protein powder works best?

Use a protein powder you like the flavor of, because the taste comes through. Unflavored or vanilla protein powder works well. Different protein powders absorb moisture differently, so adjust the dough as needed. I've used whey and whey/plant blend protein powder.
