Gluten Free Monster Cookies

These naturally gluten free monster cookies are chocked full of oats, peanut butter, chocolate chips and M&M candies. Made without flour, these cookies mix up in one bowl and ready to enjoy in about 30 minutes or less!

 

So recently I found out I have to avoid gluten. Like entirely. I didn’t panic one bit. Ok I panicked a little. Ok a lot. How would I bake without regular flour, I thought?! But then I realized there was an opportunity hear to start experimenting. With gluten free flours, and also no flour at all. Such the case, with these flourless cookies.

And as much as I love these M&M chocolate chip cookies, I love that I don’t need to use a gluten free flour for these cookies! Enter these gluten free monster cookies that are made with oats only. These are a fun twist on these flourless oatmeal cookies. This time I couldn’t resist stirring in some M&M cnadies. There’s no flour needed! How awesome is that?!

So if you or a friend have celiac disease (or perhaps you just ran out of flour!) then this flourless monster cookie recipe made without flour is the cookie you need to make!

Why This Recipe Works

• No flour needed for these oatmeal peanut butter cookies
• Soft, chewy cookies made with simple ingredients and lots of peanut butter flavor 
• Cookie dough mixes up in minutes in one bowl and is ready to be baked right away
• Great for freezing and enjoying later

Ingredients Needed

• Unsalted butter – Make sure your butter is at room temperature so it’s creamed easily together with the sugars.
• Peanut butter – I recommend smooth peanut butter, not natural peanut butter which can be too oily. You could also try using crunchy peanut butter.
• Brown sugar – If you have run out, you can make homemade brown sugar. Or try using dark brown sugar.
• Granulated white sugar
• Large eggs – Make sure you use room temperature eggs so they don’t seize up the butter. Read my full tutorial on how to bring eggs to room temperature fast.
• Baking soda
• Vanilla extract
• Old-fashioned rolled oats – Do not use quick-cooking oats which can be too fine in texture and not create quite a chewy texture. To make 100% gluten free be sure to use certified gluten-free oats.
• Semi-sweet chocolate chips – You can also use milk chocolate chips or dark chocolate chips.
• M&M candies – Regular or mini m&m candies will work.

How To Make Flourless Monster Cookies 

Position a rack in the center of the oven and preheat the oven to 350^oF (180^oC). Line two baking sheets with parchment paper.

In a large mixing bowl, using an electric mixer, beat together the butter, peanut butter, and both sugars on medium-high speed. I like to use my stand mixer fitted with a paddle attachment. 

Add the eggs, baking soda, and vanilla and beat well to combine.

Fold in the oats, chocolate chips and m and m candies stir until incorporated. 

Using a small scoop or a teaspoon, scoop out the cookie dough balls and drop them onto a prepared baking sheet about 2 inches apart.

Bake until the cookies are lightly browned, about 12 to 14 minutes. Remove from the oven and allow to cool for about 5 minutes on a baking sheet. Transfer to a wire rack to cool completely.

Store in an airtight container at room temperature for up to 1 week.

Recipe Tips

• Use room temperature ingredients. This will help the ingredients to combine more easily and create a smoother batter for these monster cookies.
• Be careful not to overbake the monster cookies. The bars are done when the edges are golden brown and the center is soft but set.
• Bake in the center of the oven. This will ensure even baking.
• Use a cookie scoop. This will make sure all cookies bake the same.

Recipe Variations

• Different mix-ins– You can add a variety of different mix-ins to your monster cookies, such as chopped nuts, dried fruit, candy pieces, or pretzels.
• Different types of chocolate– You can use any type of chocolate that you like in your monster cookie bars. Milk chocolate, dark chocolate chips, and white chocolate are all good options. You can also use a mix of different types of chocolate.
• Different spices– You can add different spices to your monster cookie bars, such as cinnamon, nutmeg, or allspice. Just add a pinch or two of your favorite spices to the dry ingredients.
• Different flavored chips– You can use flavored chocolate chips to add extra flavor to your monster cookie bars. Some popular options include peanut butter chips, butterscotch chips, and mint chocolate chips.
• Use sunflower seed butter – If you have a nut allergy, you can use swap peanut butter for this nut-free butter.
