What Are Monster Cookie Bars? 

Think of these energy bars like a healthier version of your favorite Monster Cookies! They’ve got all the classic ingredients we all look for in a monster recipe such as M&M’s, nut butter, and oats. However, we made them a little bit healthier, and turned them into a no-bake bar for a sweet treat you can feel good about eating! Sweet, salty, and so easy to make, they’re everything you could ever ask for…and more.  

Monster Energy Bar Ingredients

Unlike traditional Monster cookie recipes that require eggs and sugar, this version uses simple, (mostly) healthy ingredients you probably already have on hand. 

  • Oats – Old-fashioned oats create the best texture and ensure your bars hold together. Don’t forget to make sure they’re certified gluten-free if you follow a gluten-free diet! 
  • Almonds – Almonds ad healthy fats, fiber, and a bit of protein to these Monster Cookie Bars. 
  • Honey – Honey is crucial to ensure your bars hold together! Plus, it adds an extra touch of sweetness we love. 
  • Nut Butter – We used almond butter, but any nut or seed butter you like best can be substituted instead. 
  • Coconut Oil – A good source of medium-chain triglycerides, coconut oil helps thin out the batter so that it is easier to mold and shape into bars. 
  • Vanilla Extract – Don’t overlook the vanilla! It helps enhance the sweet flavor of these energy bars, taking them from good to great. 
  • Chocolate Chips – Feel free to use whatever variety you like best. 
  • M&Ms – For this recipe, we used classic M&M’s. However, it’s fun to swap them out for different holiday-themed candies throughout the year. 
  • Chia Seeds – Technically optional chia seeds help add fiber and plant-based protein to these energy bars, making them even more filling. 

How to Make the Best No-Bake Energy Bars

Made with just a food processor and a baking pan, this recipe couldn’t be any easier. You don’t even have to turn on the oven! Just follow the steps below, and you’ll be on your way to snacking in no time. 

  1. Process the oats and almonds until a flour-like consistency is formed. 
  2. Add the remaining ingredients except for the M&Ms and chocolate chips, and pulse until everything is well-combined. 
  3. Gently mix in the final ingredients. 
  4. Press the mixture into a 8×8 baking pan. Note: option to roll into balls for energy bites!
  5. Place in the fridge or freezer until the mixture is set, and slice into bars. 

Our Secret Tips & Tricks

Of course, these monster cookie bars are super easy to make. However, we’ve tested them quite a few times and have developed a few tips and tricks to make them even better. 

Add Milk. If the batter is too dry to stick together, try adding a splash of your favorite milk, and pulsing again. 

Add More Oats. If the batter is too wet or sticky, add in a few more oats to help it become just a little drier. 

Create Balls Instead of Bars. For an easy on-the-go option, roll your monster cookie bar batter into balls instead of bars! 

Add a Boost of Protein. If you want to make these bars even more filling, try adding in a scoop of your favorite protein! However, keep in mind that you’ll need need to thin out the batter again if you do. 

Get a Little Fancy. If you’re looking for an extra indulgent treat, feel free to add a layer of icing to the top of your bars, and don’t forget the sprinkles or extra candies, too!

How to Store Monster Energy Bars

Fridge: Transfer your energy bars to an airtight container, and keep them in the fridge for up to 1 week

Freezer: Keep your bars in the freezer for up to 2 months. However, when you’re ready to eat, we recommend letting them soften on the counter just a bit!
