Ingredients You’ll Need
Ready for the easiest gluten free cookies ever? These flourless monster cookies need just 10 simple pantry ingredients.
For the cookie dough:
- 1 cup creamy no-stir peanut butter
- 2 tsp vanilla extract
- 2 large eggs
- 2 tbsp pure maple syrup
- 1 cup gluten free rolled oats
- 1/2 cup brown sugar, packed
- 1/2 tsp salt
- 1/2 tsp baking soda
- 1/2 cup mini chocolate chips
- 1/2 cup M&M’s, plus extra for topping
Key ingredient notes: Use no-stir peanut butter like Jif or Skippy since natural peanut butter is too oily and makes cookies spread. Certified gluten free oats are essential if you’re cooking for someone with celiac disease. Mini chocolate chips work better than regular size since they distribute more evenly throughout the dough.
Step-by-Step Instructions
1. Preheat your oven to 350°F and line two baking sheets with parchment paper or silicone baking mats. Set aside while you prepare the cookie dough.
2. Beat the wet ingredients by combining peanut butter, eggs, maple syrup, brown sugar, and vanilla extract in a large mixing bowl. Stir vigorously with a wooden spoon or electric mixer on medium speed for 1-2 minutes until completely smooth and creamy.
3. Add the dry ingredients by stirring in gluten free oats, baking soda, and salt. Mix until everything’s evenly distributed and no dry pockets of oats remain visible in the dough.
4. Fold in the mix-ins by gently stirring mini chocolate chips and M&M’s into the dough until they’re evenly distributed throughout. The dough will be thick and sticky—that’s exactly right.
5. Shape the cookies by scooping 2-tablespoon portions of dough onto your prepared baking sheets, spacing them 2 inches apart. These cookies don’t spread much, so shape them into your desired thickness and diameter now. Press extra M&M’s on top for that classic monster cookie look.
6. Bake to perfection for 11-14 minutes until the edges are lightly golden brown and the tops look set but still soft. Don’t overbake—they continue cooking on the hot pan after you remove them from the oven.
7. Cool properly by letting cookies rest on the baking sheet for 5 minutes before transferring to a wire cooling rack. Moving them too soon causes them to fall apart since they’re flourless and more delicate when hot.
Essential Equipment
Large Mixing Bowl
Gluten free monster cookie dough is thick and requires serious stirring power. A 4-quart bowl gives you room to mix vigorously without ingredients flying everywhere, making the process much easier.
Cookie Scoop (2-Tablespoon Size)
A scoop ensures every cookie is identical in size so they all bake evenly. Since these cookies don’t spread, consistent sizing is crucial for uniform baking and professional-looking results.
Parchment Paper or Silicone Mats
Flourless cookies can stick to bare baking sheets even when greased. Parchment or silicone mats provide foolproof release and make cleanup effortless after you’ve devoured the batch.
Wire Cooling Rack (PREMIUM)
Air circulation underneath prevents soggy bottoms that happen when cookies cool on solid surfaces. A quality rack supports delicate flourless cookies without bending or warping under their weight.
What to Serve With Gluten Free Monster Cookies
Want to complete your dessert spread? These pairings turn cookie time into a special treat everyone enjoys.
Classic beverages: Ice-cold milk is non-negotiable for dunking these peanut buttery cookies. Hot coffee or Dalgona Whipped Coffee makes an excellent afternoon pairing for adults.

Storage and Reheating Guide
Room Temperature Storage
Store gluten free monster cookies in an airtight container at room temperature for up to 5 days. Place parchment paper between layers to prevent them from sticking together. They stay chewy and delicious throughout the week.
Refrigerator Storage
Refrigerate cookies in an airtight container for up to 2 weeks if you want them to last longer. Bring to room temperature before eating for best texture, or microwave for 10-15 seconds to warm them slightly.
Freezer Storage
Freeze baked cookies in freezer bags or airtight containers for up to 3 months. Freeze cookie dough balls on a baking sheet until solid, then transfer to freezer bags. Bake frozen dough balls adding 2-3 extra minutes to the baking time.
Gluten Free Monster Cookies Recipe Variations
Want to customize these flourless treats? These swaps keep the chewy texture while adding your personal twist.
Chocolate peanut butter version: Use chocolate peanut butter instead of regular for double chocolate flavor. Add 1/4 cup cocoa powder to the dough and reduce oats to 3/4 cup for ultra-rich cookies.
Nut-free alternative: Swap peanut butter for sunflower seed butter or cookie butter for nut allergies. The texture stays identical while accommodating dietary restrictions. Try Amazing Chickpea Cookie Dough for inspiration.
Extra candy versions: Try Reese’s Pieces instead of M&M’s, or mix in chopped peanut butter cups for more peanut butter punch. White chocolate chips and dried cranberries create a sweeter, fruitier variation.
Pro Tips & Tricks
Want bakery-quality gluten free monster cookies every time? These techniques guarantee perfect flourless cookies.
Use no-stir peanut butter exclusively because natural peanut butter contains too much oil that separates during baking, making cookies greasy and causing excessive spreading on the pan.
Don’t skip the 5-minute rest after baking since flourless cookies need time to firm up on the hot pan before they’re sturdy enough to transfer without breaking apart.
Shape cookies carefully before baking because they won’t rise or spread like traditional cookies—whatever shape you create on the pan is exactly what you’ll get after baking.
Press extra M&M’s on top right before baking so they’re visible in the finished cookies and create that iconic monster cookie appearance everyone recognizes.
Frequently Asked Questions
Can you make gluten free monster cookies recipe with quick oats?
Old-fashioned rolled oats work best for proper texture, but quick oats work in a pinch. Don’t use steel-cut oats since they won’t soften enough during baking. Rolled oats create the perfect chewy texture these cookies need.
Why are my monster cookies falling apart?
You didn’t let them rest on the baking sheet long enough after removing from the oven. Flourless cookies are fragile when hot and need 5 full minutes to firm up before moving to a cooling rack.
Can I use natural peanut butter instead?
No, natural peanut butter is too oily and makes these gluten free monster cookies spread excessively and turn out greasy. Stick with no-stir varieties like Jif, Skippy, or Peter Pan for best results.
How do I know when flourless cookies are done?
The edges should be lightly golden brown and the tops should look set but still slightly soft in the center. They continue baking on the hot pan after removal, so slight under-baking prevents dry cookies.
Can you freeze monster cookie dough?
Yes, roll dough into balls and freeze on a baking sheet until solid, then transfer to freezer bags for up to 3 months. Bake directly from frozen, adding 2-3 extra minutes to the baking time.
What makes these cookies gluten free?
These use rolled oats instead of wheat flour, making them naturally flourless and gluten free. Make sure to buy certified gluten free oats if you’re cooking for someone with celiac disease since regular oats can be cross-contaminated.
