Flourless Gluten Free Monster Cookies

These flourless gluten free monster cookies might just be the perfect mashup of all the best flavors for a cookie. They are soft, chewy, and have pretty much the best flavor combination ever invented: chocolate and peanut butter. I mean, it’s hard to top that!

Monster Cookies

Monster cookies were one of my childhood favorites growing up. There’s just something about cookies that are made with oats that I totally love. I also have a soft spot for oatmeal raisin cookies, probably for that same reason. But back to the monster cookies. They are made with only a few ingredients and don’t contain flour or butter. The recipe yields about 20 cookies so there are usually some left to save in the freezer for later (or not).

Ingredients In Flourless Monster Cookies

These irresistible flourless gluten free monster cookies are made with a few simple ingredients and don't take long to make. They have that classic monster cookie flavor but without the added not-so-great ingredients. 

Here’s what you’ll need to make these cookies:

• eggs: This recipe calls for 2 eggs. I have not tried to substitute the eggs with a flax egg but let me know in the comments below if you do. 
• smooth peanut butter: I use natural peanut butter that is only made with peanuts and a little bit of salt. If you prefer, you could try using crunchy peanut butter or almond butter also.
• vanilla extract: I love a little vanilla extract in a cookie recipe. This recipe uses 1 tsp.
• maple syrup: Part of the sweetness in this recipe comes from the maple syrup. I use all natural pure maple syrup.
• gluten free rolled oats: Make sure you use rolled oats for this recipe, not quick or steel cut. You will get the best texture using the gluten free or regular rolled oats.
• baking soda: Baking soda helps with the baking process and encourages the cookies to spread and bake evenly.
• sea salt: You could also add a touch of flaky salt on top of the baked cookie to enhance the flavor.
• brown sugar: The other sweetener in this recipe is brown sugar. When it is paired with a little bit of maple syrup, it makes for a perfectly sweetened monster cookie.
• cinnamon: I love to add a little bit of cinnamon in this monster cookie recipe to add another complimentary flavor element. 
• M&M’s or vegan M&M’s: if you are following a vegan diet, opt for the vegan M&Ms. They should taste just as good as the regular in this recipe.
• chopped pecans: the pecans add a little texture to the monster cookie and pairs really well with the peanut butter and chocolate flavors.

How to make flourless gluten free monster cookies

Like I mentioned earlier, these monster cookies are easy to make and require no refrigeration time. They can also be stored in the freezer for a sweet snack at a later date.

1. Preheat the oven to 350°F and line a baking sheet with parchment paper.
2. In a large bowl, mix wet ingredients together on medium speed with a hand mixer until smooth and combined.
3. Add the dry ingredients to the wet ingredients mixture. Mix until incorporated. Fold in the M&M’s and pecans.
4. Using a large cookie scoop, form into balls and place on the prepared cookie sheet. Flatten the balls slightly with your hands and place extra M&M’s on top. 
5. Bake cookies for 10-12 minutes or until golden around the edges. Allow the cookies to cool on the baking sheet for at least 10 minutes before transferring to a cooling rack. Enjoy!

Feel free to customize!

In this recipe I’ve included M&M’s and pecans for the mix-ins but feel free to customize this part with what you have in your pantry. You could try adding your favorite nuts, chocolate chips, or even coconut flakes. If you try a different variation, leave a comment below. I'd love to hear how it turned out. 

Why are these monster cookies flourless?

I made these monster cookies flourless for a healthier alternative to the traditional monster cookie recipes. They don’t have the added flour which means they are gluten free and can be easily made dairy free.

How to store flourless monster cookies

If you have leftover cookies (that’s a big IF) they are pretty easy to store. Store the cookies on the counter for up to 2 days or store in the refrigerator in an airtight container. Alternatively, you can freeze these cookies in a freezer safe bag for up to 2 months. My husband loves to keep a bag of these monster cookies in the freezer for an easy snack to grab on the go.
