These monster cookie protein balls are a fun, lighter spin on the classic bakery cookie. They come together in one bowl and make an easy, meal prep–friendly snack with 5g protein each.
Monster cookies have always felt like pure joy to me. Peanut butter, oats, chocolate chips, and candy all in one bite is hard to beat, especially when you’re craving something sweet.
I already have a recipe for healthy monster cookies, but naturally I had to turn that same combo into protein balls. These monster cookie protein balls are quick to make, perfect for prepping ahead, and exactly the kind of snack I like having on hand for busy afternoons, post-workout bites, or late-night sweet cravings when I want something homemade instead of grabbing another cookie.

Why I Love These Monster Cookie Protein Balls
- High-protein snack: Each bite packs about 5g protein from the peanut butter and protein powder, making these great for staying full between meals.
- One-bowl prep: Everything gets mixed together in minutes, which means minimal dishes and a fast path to snack time.
- Great for meal prep: These protein balls hold up well in the fridge or freezer, making them perfect for grab-and-go snacking all week.
Ingredients Needed
- old fashioned rolled oats – adds texture and makes the protein balls hearty and filling instead of soft and cakey. You can make your own oat flour by blending rolled oats into a fine powder.
- drippy peanut butter – the main flavor driver here and what helps bind everything together. Natural peanut butter works best for that classic monster cookie taste.
- maple syrup – brings just enough sweetness to balance the peanut butter and chocolate without overpowering everything else.
- vanilla protein powder – boosts the protein and keeps these feeling more like a satisfying snack than dessert. I used Truvani vanilla protein powder, but your favorite brand will work.
- mini chocolate chips – little bursts of chocolate in every bite, which is exactly what you want in a monster cookie style treat.
- mini M&M’s – gives these their classic look and a fun crunch that makes them feel festive and playful.
How to Make Monster Cookie Protein Balls
Step 1: Add all of the ingredients to a large bowl and stir until a thick dough forms. It may look dry at first, but keep mixing. Using your hands toward the end helps everything come together.
Step 2: Scoop the dough and roll into bite-sized balls. Enjoy right away or store in an airtight container in the fridge or freezer until ready to eat.
Brittany’s Recipe Tips for Success
- Use natural, runny peanut butter: Drippy peanut butter mixes much more easily than thick or stiff styles and helps everything come together without extra liquid.
- Stir, then knead: The dough can feel thick at first, so start with a spoon and finish mixing with your hands to get everything fully combined.
- Adjust dryness as needed: If your mixture feels crumbly, add a teaspoon or two of almond milk or water until it holds together when pressed.
- Chill for cleaner scooping: Popping the dough in the fridge for a few minutes can make rolling easier if things feel sticky.
How to Store and Meal Prep
- Refrigerator: Store the balls in an airtight container for up to one week. They keep their soft, doughy texture and the flavor stays delicious.
- Freezer: Freeze them in a single layer until firm, then transfer to a freezer safe container. They keep well for up to three months. Let them sit at room temperature for a few minutes before eating.
- Meal prep tip: Make a double batch and freeze half so you always have a quick protein snack ready to go. These are perfect for lunch boxes, holiday travel or busy days when you want something festive and filling.

Monster Cookie Protein Balls
Ingredients
- 1 ½ cups old fashioned rolled oats
- 1 cup drippy peanut butter
- ¼ cup maple syrup
- 2 scoops (50-60g) vanilla protein powder
- 1 teaspoon vanilla extract
- ¼ teaspoon sea salt
- 3 Tablespoons mini chocolate chips
- 3 Tablespoons mini M&M’s
Instructions
- Place all ingredients in a large bowl.
- Stir to combine. Getting the mixture to combine takes a little arm muscle and it may seem too thick at first, but it will come together as you keep mixing. I used my hands to knead the dough near the end and that seems to help.
- Once combined, use a small cookie scoop to scoop and form the dough into balls.
- Store in a covered container in the fridge or freezer.
Notes
- Texture will vary by protein powder: Every brand absorbs liquid differently. If your dough feels dry, add a splash of milk. If it feels too soft, add a little extra oat flour until it firms up.
- Storage: Keep these protein balls in an airtight container in the fridge for up to one week or freeze for up to three months.
