These giant flourless gluten free monster cookies are thick, chewy, and loaded with rich peanut butter flavor. They are like a cross between an oatmeal cookie and a peanut butter cookie.

Not only does this recipe make giant cookies, but it makes a whole lot of them! With 40 cookies per batch, you will have more than enough to share. The best thing about monster cookies is that there are no rules about mix-ins. While most recipes start with a peanut butter and oatmeal cookie base, there’s an opportunity for creativity when it comes to what else you put in them! This recipe is packed with chocolate chips and raisins but if you can tolerate dairy, other options include M&M candies, white chocolate chips, dark chocolate chips, chopped nuts, or even shredded coconut. No matter what you choose to add to your cookies, this tried and true recipe is definitely one to add to your recipe book.

Why this recipe is the best!
This is one of those cookie recipes that no one will believe is gluten and dairy free. The flavor and texture are just as good, if not better than the traditional version. You can even make this recipe without the refined sugars and it’s equally as delicious (see ingredients and substitutions). Another great thing about these cookies is that like these peanut butter cookies, they can easily be made with either creamy or crunchy peanut butter. Here’s what else you’ll love about these flourless gluten free monster cookies:
- They are incredibly quick to make in just a little over half an hour
- You can prep the dough in just one bowl, this strawberry cake is a one-bowl recipe too
- The dough only has a 10 minute rest time (more on rest times here) and doesn’t require chilling
- The recipe makes a large batch of 40 giant bakery-style monster cookies
- You can make the dough ahead of time and refrigerate it for up to 2 days before baking
- These cookies stay fresh for up to 4 days at room temperature

This cookie recipe offers quite a bit of room for customization. That being said, there are some necessary steps to take to achieve gluten free cookie perfection. Follow these baking tips to ensure your flourless gluten free monster cookies turn out extra soft and chewy.
1. Use room temperature ingredients
Whether you're baking with gluten free ingredients or not, it’s always a good idea to use room temperature ones. Room temperature ingredients blend more evenly when mixed than cold ingredients do (more on this in my baking masterclass). This helps create a uniform cookie dough for the best possible cookie texture.
2. Measure specified ingredients by weight
Since baking is an exact science, accurately measuring your ingredients is one of the keys to success. For this monster cookie recipe, use a digital scale to measure the granulated and brown sugars, oats, chocolate chips, and raisins by weight.
3. Scrape down the mixing bowl with a spatula
Use a rubber spatula to scrape down the sides of the bowl throughout the mixing process. This ensures that all of the ingredients are fully mixed into the dough.
4. Let the dough rest for 10 minutes
Allow the cookie dough to rest for 10 minutes before portioning and baking it. This allows for the dry ingredients to fully absorb the liquid ingredients and for the flavors to deepen. This process contributes to the perfectly chewy texture of these cookies.
5. Allow refrigerated cookie dough to warm up before baking
If you make this cookie dough in advance and store it in the refrigerator, you’ll need to let it warm up before baking. Allow the dough to sit for about 30 minutes at room temperature before scooping it onto the baking sheet.
6. Helpful tools
Here are a few tools that will help make prepping your flourless gluten free monster cookies a breeze:
- Digital scale
- Stand mixer
- Mixing bowl
- Rubber spatula
- Sturdy spoon
- Large cookie scoop (3 tablespoon)
- Parchment paper
- Baking sheet
- Wire cooling rack
Ingredients & substitutions

- Brown sugar - The brown sugar can be replaced with Swerve brown sugar substitute for a sugar free option.
- Granulated sugar - The granulated sugar can be swapped out for Swerve granular sweetener for a sugar free option.
- Peanut butter - This cookie recipe was tested using Jif brand peanut butter. You can use either crunchy or creamy peanut butter. However, I do not recommend using any varieties that require stirring.
- Eggs - I do not recommend using a substitute for the eggs in this recipe.

Measurements for each ingredient, along with complete instructions for making the cookies are in the recipe card below.
Note about oats
This recipe has been tested with both quick cook oats from Bob's Red Mill and these rolled oats from Nuts.com. Both work equally well. I would advise against using steel cut or old fashioned oats as the cookies seem to turn out a bit drier.
You can quickly prepare this flourless gluten free monster cookie dough in just 15 minutes. Before getting started, be sure all of your ingredients are at room temperature. First, add the vegan butter, brown sugar, and granulated sugar to the bowl of a stand mixer (step 1 above). Cream the butter and sugars on medium speed for 30 seconds. Next, add the peanut butter, eggs, and vanilla extract (step 2) and mix on low speed for 15 seconds. Stop the machine and scrape down the sides of the bowl with a rubber spatula (step 3). Then, mix again for 30 seconds on medium speed.
Add the oats, baking soda, and ground cinnamon (step 4) and mix on low speed for 15 seconds. Stop the machine again to scrape down the bowl. Mix on medium speed for 15 seconds. Finally, add in the chocolate chips and raisins (step 5) and mix with a sturdy spoon until fully combined (step 6). Set the dough aside to rest for 10 minutes.
Baking & serving
Meanwhile, preheat the oven to 350°F. Prepare your baking sheets by lining them with parchment paper. Once the cookie dough is done resting, use a 3 tablespoon cookie scoop to portion the dough onto the lined baking sheets. Slightly pat down each scoop of dough. Then, place them in the oven to bake for 12-14 minutes or until they are light golden brown, being careful not to overbake them. They will brown very quickly. Once they are done, remove them from the oven and let the baking sheets cool on the wire cooling racks. These cookies can be served warm or cool.
Other mix-in ideas
If you can tolerate dairy, other mix-in options are: M&M candies, white chocolate chips, dark chocolate chips, and even Reese's peanut butter pieces. Some non-dairy ideas are: chopped nuts, shredded coconut, dried cranberries or sunflower seeds.
Yes, peanut butter is naturally gluten free. Most brands of peanut butter contain only gluten free ingredients like peanuts, salt, and other additives like sugar and oil. Check product labels when purchasing peanut butter to ensure there is no risk of gluten cross-contamination. I use Jif peanut butter in this cookie recipe.
Yes, natural peanut butter works in this recipe as long as it is the kind that does not need to be stirred. Peanut butter that requires stirring will make your dough greasy and crumbly.
You can store these flourless gluten free monster cookies at room temperature in a sealed bag or under a cake dome. They will stay fresh for up to 4 days. These cookies are best when fresh so I do not recommend storing them in the freezer.
Yes, this cookie dough can easily be prepared ahead of time. Store it in the refrigerator in a sealed bag or airtight container until you are ready to bake it. It will stay fresh for up to 2 days. Let the dough sit for 30 minutes at room temperature to warm up before portioning and baking. If you want to store the dough for a longer period of time, store it in the freezer and thaw it before baking.
