Helpful Kitchen Tools
What You Need
- Peanut Butter: this recipe calls for all-natural peanut butter to emulate what is in monster cookies, but any kind of nut butter will work.
- Protein Powder: make sure that you like the taste of your vanilla protein powder as it adds flavor and sweetness to your balls. Check out our favorite protein powders here.
- Rolled Oats: rolled oat are a classic monster cookie ingredient. They add whole grains and give these balls a nice bite.
- Chia Seeds: while chia seeds aren’t classically in monster cookies, we decided to up the nutrition with them.
- Honey: honey adds all natural sweetness to your balls. We don’t recommend swapping this for anything else as honey is naturally sticky and helps hold your balls together.
- Vanilla: a little vanilla extract brings out the peanut butter flavor.
- Mini Chocolate Chips and Mini M&Ms: whatever you do, do not skip either of these! They are classic monster cookie ingredients and oh-so necessary for this recipe.
Peanut butter protein balls are the perfect high-protein snack to munch on post-workout or mid-day when you need something to tide you over!
- Add: add all of the ingredients into a large bowl.
- Mix: mix to combine, adding water by the teaspoon until you’ve reached a cookie dough-like consistency.
- Roll: use a 1 tablespoon cookie scoop to scoop dough into your palm. Roll them into balls and repeat.
- Store: Store balls in the fridge for up to 2 weeks or in the freezer for up to 3 months.

Monster Cookie Protein Balls
- 1 cup drippy all-natural peanut butter we use Trader Joe’s Brand or Good and Gather
- 1/3 cup vanilla protein powder we used Garden of Life*
- 1/2 cup rolled oats
- 1 tablespoon chia seeds
- 2 tablespoons honey
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 1/4 cup mini chocolate chips
- ¼ cup mini m&ms
- Optional: 1–4 teaspoons water*
- Place peanut butter, protein powder, rolled oats, chia seeds, honey, vanilla extract, salt, mini chocolate chips and m&ms into a medium bowl.
- Use a wooden spoon or your hands to mix the dough together. At this point, you’ll begin to add water by the teaspoon.
- Depending on how drippy your peanut butter is, you’ll need to add more or less water. The water not only helps moisten things so your balls hold shape, but they actually help your balls become less chalky.
- Use a 1 tablespoon cookie scoop to scoop dough into your palms. Roll into balls until all dough is gone. You should get somewhere between 14-16 balls.
- Store in the refrigerator for up to a week or in the freezer for up to 3 months.
Tips & Notes
- Be sure you use drippy peanut butter or the consistency will be off.
- We used our favorite monster cookie ingredients but feel free to add raisins or coconut flakes as well.
- If your balls aren’t holding together or are too chalking add more water but only a little bit at a time until it reaches your desired consistency.
- Storage: Store in the fridge for up to 2 weeks or in the freezer for up to 3 months.
- The nutrition for this recipe depends on the protein powder you used.
I love the ball recipes without dates! Has anyone tried using unflavored protein powder? I imagine you could just up the vanilla and sweetener. I generally find recipes too sweet and typically decrease any sugar/honey by half, so maybe I would just keep the honey as is, especially with M&M candy.
Also thoughts about maple syrup instead of honey? Thanks!
I haven’t tried these with unflavored protein powder, but would do exactly what you’re saying — and just taste for your sweetness liking before rolling into balls. And honey really helps these balls stick together, so I wouldn’t sub for maple 🙂
These are DELICIOUS and sooo easy to make, packed with nutrition! My husband asked me to do them right after the first batch was inhaled 😁 type of peanut butter does set the flavor on this one so make sure its a good one!
Also, we excluded the mini m&ms and they’re still delicious!
I made these with my toddler. He loved being able to taste everything as he was adding it, mostly the chocolate.🤣 He said “these are very yummy!”. We will double the batch next time, they are going fast.
(I didn’t have any honey so I used date syrup instead. They turned out great with it!)
CUTE!! I’m glad you guys loved it!
So good! Added Peanut Butter flavored protein powder and *chef’s kiss* they are perfect. I’ve already eaten 3 today!
Oh YUMMMM. Great call on the PB protein powder!
Just made these with my kiddo and they are PHENOMENAL! Used the protein powder you recommended and they’re so so good. It’ll be hard just eating one lol.
These are delicious!
These were delicious! I never have protein powder so I just used extra oats and they were great! I can’t wait to snack on them through the week 🙂
Made these today! Very good! ( thank you for making a energy ball without using dates!)
