3-Ingredient Peanut Butter Oatmeal Energy Balls

My kids come home from school starving and these No-Bake Monster Cookie Energy Balls are just what they need to help curb their hunger until dinner.

Peanut Butter Energy Balls are perfect when it is too late for a big snack because dinner is right around the corner. The M&M’s add just enough chocolate and color to make them fun and they will think they are getting a special treat!

Looking for something similar? Check out my Peanut Butter Oatmeal Bars here – they are great if you want to leave out the M&M’s. One of my kids other favorite after-school treats is our Chocolate Chip Banana Bread! This is always a hit and a good way to use up ripe bananas!

Why are they called energy balls?

The ingredients in energy balls will give you a nice boost of energy (hence the name). They are packed with protein, so they help you curb those annoying afternoon hunger pains.

They make the perfect pick-me-up afternoon snack or grab-n-go breakfast.

Monster Cookie Energy Balls Ingredients


  • Quick Oats
  • Peanut Butter
  • Honey
  • Mini M&M’s (Optional)

Side note – a useful kitchen tool that I love is my silicone baking mat! Place the balls on a baking sheet with a silicone baking mat to keep the balls from sticking when refrigerating them.

How to Make Oatmeal Energy Balls (No-Bake; 3 Easy Steps)

  1. Combine all ingredients and mix well.Monster Cookie Energy Balls dough mixed
  2. Roll into balls and set on a baking sheet roll dough in a ball
  3. Refrigerate for about an hour.Oatmeal Energy Balls on a cookie sheet


  • If the dough is super sticky, place the mixed dough into the refrigerator for about 30 minutes before rolling them into balls. They will go together much easier and not be as sticky on the hands!
  • You can use a cookie scoop if you want uniform sizes, I made mine about the size of a golf ball.

Add-Ins for Oatmeal Power Balls

The best thing about these Oatmeal Energy Balls is that there really are no rules! You can pretty much add in anything to make them exactly what you like!

Try adding some “superfoods” to make them even more nutritious, like flaxseeds or chia seeds. Or instead of M&M’s, try some chocolate or cinnamon chips!

Frequently Asked Questions

Can you make energy balls peanut free?

If your school is peanut-free or you have a peanut allergy, try substituting the peanut butter for sun butter, pecan butter, almond butter, cashew butter, etc.
It will change the consistency and taste a bit, but try testing it out until you find one you like.

How long to energy balls last in the refrigerator?

If you place your energy bites in a container in the fridge, you can keep them for about a week. If you freeze them, you can keep them for up to three months!

How do you freeze Monster Cookie Energy Balls?

Once you roll the balls, place them on a cookie sheet and place them in the freezer for about 1-2 hours. After they are frozen, place them in either an airtight container or a zip lock bag and keep them in the freezer until you are ready to eat them.
Personally, I love to keep them in the freezer (they are cold and take longer to eat).
Pro-Tip: keep them in the freezer and then pop them in your kid’s lunches – they will be perfect come lunchtime (or a packable after-school snack)!

Can you eat raw oats in energy balls?

Yes, you can eat raw oats in energy balls, especially when combined with other ingredients.

How healthy are energy balls?

Energy balls are a combination of protein, good carbs, healthy fats, and high in fiber – but like everything, they should be eaten in moderation. They are still high in calories, so it is best to enjoy them in smaller quantities.

How many stars would you give this recipe?


  1. 5 stars
    Love, love , love this snack…for me! Perfect quick pick me up before picking up my first graders from specials each afternoon! Also great taken frozen to the beach & pool!

  2. 3 stars
    I gave it 3 Stars because they are good, but I won’t be making them again, they are extremely messy, for how many they make. (20)

  3. what is the serving size for the nutritional information? is it per ounce or ball…if ball then approximately how much should each ball weigh. thanks.

  4. Is the nutritional information for one ball? 2 balls? I’m doing keto and weight watchers so in order for me to figure out how many points these balls are worth, I need to know if it’s per ball or for a certain amount of ounces. Thank you
