What are Monster Cookies?
Traditional Monster Cookies are thick, soft, and chewy peanut butter cookies with oats and M&Ms. Why they are called Monster Cookies is not really known. But some say it’s because they combine different types of cookies (peanut butter, oatmeal, M&M) making them like the Frankenstein of cookies with everything mashed up into one. Whatever the reason, they are a delicious mash up of cookies!
While I’m a huge fan of homemade cookies, and an advocate for enjoying a small dessert daily, many nostalgic cookie flavors can include a lot of harmful ingredients! Traditional Monster Cookies are made with M&Ms which include artificial colors, artificial flavors, soy, seed oils and more.
But, now you can enjoy these Eggless Monster Cookies made with organic ingredients. If you are looking for more nostalgic treats made better, check out Homemade Twix Bars, Organic Sugar Cookie Bars With Frosting, Vegan Snickers Bars, or Chocolate Dipped Animal Crackers.
Ingredients

- Light Brown Sugar: Using all light brown sugar makes these organic cookies extra chewy with a rich flavor. I use my homemade light brown sugar, but store bought also works.
- Peanut Butter: Use organic creamy peanut butter, my favorite is Costco! Theirs has the best flavor and it only has 2 ingredients: peanuts and salt. If you prefer to use almond butter, you can but these are traditionally made with peanut butter.
- Milk: Use whole milk for the best results. You need the fat in whole milk, as water can dry out cookies so don't use a skim or reduced fat milk. Dairy free or plant-based milk like coconut, almond or oat milk is also a great option.
- Baking Soda: I use baking soda as this is a quick rise bake and there’s an acid (brown sugar) to react with the baking soda. Be sure to check out my post the Difference Between Baking Soda and Baking Powder for more info on leavening agents.
- Chocolate Candies: I use organic chocolate candies from Azure. This is the only place I’ve found all organic chocolate candies and they’re so good! If you don't have chocolate candies, you can use chocolate chips in their place.
- Raisins: I use organic raisins for added sweetness and texture. This is optional as they are not in traditional Monster Cookies, but I really love what they add to these organic cookies!
- Oats: I use organic rolled oats, which are the same as old fashioned oats.

Baker’s Tips for Eggless Monster Cookies
- Always weigh ingredients for the best results.
- Make sure your butter is soft. I like to allow butter to soften naturally on the counter before baking.
- I use milk in place of eggs in these eggless cookies. Definitely use whole milk as you need that fat, and reduced fat or skim milk is more water, which can dry out cookies.
- I add raisins into these Organic Monster Cookies as I love the sweetness paired with the peanut butter, oats, and chocolate candies. These are optional and I’ve made them both ways, so if you don’t want them just leave them out.
- Store cookies in an airtight container so these stay soft.
- Vegan — Replace the butter and milk with vegan butter (my favorite is Miyoko’s) and the milk with coconut milk for vegan monster cookies.
- High Altitude — Bake at 375°F for 11 to 13 minutes or until the cookies look cracked and the edges look dry.

Recipe FAQ’s
Monster cookies have the addition of peanut butter and chocolate coated candies along with oats! So, they are like a loaded oatmeal cookie! I also like to add raisins into mine.
I use organic creamy peanut butter, my favorite is Costco! You don't want to use crunchy as we don't want the pieces of peanuts here, we need a smooth peanut butter for the right texture. Be sure to use a high quality organic peanut butter with minimal ingredients for the best flavor.
Yes! This is what I recommend using and what I used here.
I use milk as an egg replacer, which is one of my favorites in cookies. It provides fat and moisture, just like eggs.
Yes, if you don’t want them just omit them. But I really love this addition to the classic!
Yes, just replace the butter with vegan butter (my favorite is Miyoko's) and the milk with coconut milk. Luckily the organic chocolate coated candies I use are vegan!
Yes, you can! They just won't have the same colorful look or candy texture.
Because this monster cookie recipe is eggless, they are actually softer and chewier than monster cookies with eggs. Eggless cookies
No, this is a no chill cookie recipe!
The edges will be golden brown and dry and the middle will look set. Because these are eggless monster cookies, there's no worry of under baking them!
These are super thick cookies, so they don't spread much. Make the cookie dough balls about the size you want the cookies to be and be sure they are a round disk (see video).
Incorrect measuring is most likely what made the cookies dry (too much flour, not enough milk). Or, sometimes when using natural peanut butter it can be dry at the bottom of the jar, if you used this part, it can cause cookies to be dry. So, be sure to stir peanut butter well and use the creamy smooth part. I usually just throw out those dry bits at the end of the jar!
Be sure to store in an airtight container so these cookies stay soft and chewy. They’ll be okay at room temperature for 7 days but will last even longer in the fridge (2 weeks). Store in the freezer for up to 3 months and then just thaw to enjoy!
Yes, if you want to prep the dough in advance, you can portion it out onto one baking sheet in the dough balls. Pop the tray in the freezer, let them harden, and then transfer to a freezer safe container or bag. Remove them and allow them to come to room temperature before baking off.
