Quick Monster Cookie Protein Balls

If you ask me, monster cookie protein balls are a genius snack idea.

These no-bake treats pack all the flavors of your favorite monster cookies into bite-sized form, with a healthy twist. Creamy peanut butter and honey hold together a mix of oats, chocolate chips, and M&Ms, while protein powder adds an extra nutritional boost.

They’re perfect for busy days when you need a quick pick-me-up or post-workout snack. Plus, they’re so simple to make that my kids love helping roll them into balls – though quite a few M&Ms mysteriously disappear in the process.

It’s a fun, portable treat that satisfies your sweet tooth while keeping you energized throughout the day.

What Kind of Peanut Butter Should I Use?

Natural peanut butter is the way to go for these protein balls, but make sure it’s the drippy, well-stirred kind. The ingredients list should only contain peanuts and maybe a bit of salt – skip the ones with added oils or sugar since they can make the mixture too soft. If your peanut butter has separated (you know, with that layer of oil on top), give it a good stir before measuring to make sure you get the right consistency. Fresh-ground peanut butter from your local store’s grinding station works great too, just let it come to room temperature before using it in your recipe so it mixes more easily with the other ingredients.

Options for Substitutions

These protein balls are super adaptable – here’s how you can mix things up:

• Peanut butter: Not a peanut butter fan or have an allergy? Try almond butter, sunflower seed butter, or cashew butter instead. Just make sure it’s the natural, drippy kind for the right consistency.
• Protein powder: While vanilla protein works best here, you can use chocolate or unflavored protein powder too. If using unflavored, you might want to add an extra 1/2 teaspoon of vanilla extract. Plant-based or whey protein both work fine.
• Rolled oats: Quick oats can work in place of rolled oats. For a grain-free version, try using crushed nuts or coconut flakes, though this will change the texture.
• Chia seeds: You can swap these with ground flaxseed or hemp hearts – they all provide similar nutrition and binding properties.
• Honey: Maple syrup or agave nectar work great for a vegan version. Just note that the mixture might be slightly softer.
• Mix-ins: The chocolate chips and candies are totally customizable! Try chopped nuts, dried fruit, or different types of chocolate chips. Just keep the total amount of mix-ins to about 1/2 cup.

Watch Out for These Mistakes While Making

The biggest challenge when making protein balls is getting the consistency right – if your mixture is too dry and crumbly, add water one teaspoon at a time until it holds together, but be careful not to add too much or they’ll become sticky and difficult to roll.

Another common mistake is using cold peanut butter straight from the fridge, which makes the mixture harder to work with – instead, let your peanut butter come to room temperature and ensure it’s well-stirred before measuring.

The protein powder you choose can make or break these balls, so stick to whey or plant-based protein powders you’ve used before, as some brands can be overly drying or leave an unpleasant aftertaste.

For the best texture and binding, avoid overworking the mixture when combining ingredients – mix just until everything comes together, then roll quickly with slightly damp hands to prevent sticking.

What to Serve With Monster Cookie Protein Balls?

These protein-packed snack balls are perfect for grabbing on their own, but they’re even better when paired with your favorite drink! A cold glass of milk (regular, almond, or oat) makes these taste just like classic monster cookies while helping balance out the peanut butter. For a post-workout treat, try having them alongside your protein shake or smoothie – I especially like pairing them with a banana smoothie since peanut butter and banana are such good friends. If you’re packing these for lunch or an afternoon pick-me-up, they go great with a hot cup of coffee or tea to create that cozy coffee shop vibe at home.

Storage Instructions

Keep Fresh: These protein balls are perfect for grab-and-go snacks! Pop them in an airtight container and keep them in the fridge for up to 1 week. I like to place a piece of parchment paper between layers to prevent them from sticking together.

Freeze: Want to make a bigger batch? These little energy bites freeze really well! Place them in a freezer-safe container or zip-top bag and they’ll stay good for up to 3 months. It’s such a time-saver to have these ready to go when you need a quick snack.

Thaw: When you’re ready to enjoy your frozen protein balls, just transfer them to the fridge the night before. If you’re in a hurry, let them sit at room temperature for about 30 minutes – they’ll be perfect for snacking!

Estimated nutrition for the whole recipe (without optional ingredients):

• Calories: 1200-1300
• Protein: 40-50 g
• Fat: 70-80 g
• Carbohydrates: 120-130 g

Ingredients

• 1 cup smooth natural peanut butter
• 1/3 cup vanilla-flavored protein powder
• 1/2 cup rolled oats
• 1 tablespoon chia seeds
• 2 tablespoons honey
• 1 teaspoon vanilla essence
• 1/4 teaspoon salt
• 1/4 cup mini chocolate chips
• 1/4 cup mini candies (such as m&ms)
• Optional: 1–4 teaspoons water

Step 1: Combine Ingredients

In a medium bowl, add the following ingredients: peanut butter, protein powder, rolled oats, chia seeds, honey, vanilla extract, a pinch of salt, mini chocolate chips, and m&ms.

Make sure all ingredients are readily accessible to ensure a seamless mixing process.

Step 2: Mix and Adjust Consistency

Use a wooden spoon or your hands to mix the ingredients together, forming a cohesive dough.

As you mix, begin adding water by the teaspoon.

The amount of water needed will vary depending on the consistency of your peanut butter—drippier peanut butter may require less water, while thicker peanut butter might need more.

The water helps moisten the dough and reduces any chalky texture, ensuring the balls hold their shape well.

Step 3: Shape the Dough into Balls

Once the dough reaches the desired consistency, use a 1-tablespoon cookie scoop or a similar utensil to portion out the dough.

Roll the dough portions between your palms to form smooth, round balls.

Continue this process until you have shaped all the dough, which should yield approximately 14-16 balls.

Step 4: Store and Enjoy

Place the formed energy balls in an airtight container.

Store them in the refrigerator for up to a week for a quick, protein-packed snack.

For longer storage, place them in the freezer, where they will keep for up to 3 months.

Allow the energy balls to come to room temperature or enjoy them directly from the fridge whenever you need a nutritious bite.

Enjoy!
