Ingredients You’ll Need

3 large eggs: They provide moisture and structure to your cookies. Make sure they’re at room temperature for the best mixing.
1¼ cups packed light brown sugar: This gives the cookies a rich, caramel-like flavor and chewy texture. You can substitute with dark brown sugar for a deeper taste.
1 cup granulated sugar: Adds sweetness and balances the flavors. Coconut sugar can be a great alternative.
1/2 cup (1 stick) salted butter (softened): The butter adds richness. It’s best to let it sit at room temperature to soften.
1½ cups creamy peanut butter: This is a star ingredient! It contributes creaminess and a nutty flavor. You can use almond butter for a nut-free option.
2 teaspoons baking soda: This is the leavening agent that helps the cookies rise. Make sure to check your baking soda’s freshness for the best results!
1 teaspoon vanilla extract: A splash of vanilla enhances all the other flavors. Use pure vanilla extract for a more robust flavor.
½ teaspoon salt (I use sea salt): It enhances the sweetness and balances flavors. Adjust according to your taste.
4½ cups quick oats: These give the cookies their hearty texture. If you’re looking for a gluten-free option, ensure your oats are certified gluten-free.
1 cup miniature semi-sweet chocolate chips: These sweet little gems melt into gooey pockets of chocolate in the cookies. You can use dark chocolate chips for a richer flavor.
1 cup mini M&M’s: They provide fun color and a hint of candy crunch. If you’re avoiding artificial colors, look for natural alternatives.

How to Make No Flour Monster Cookies

Preheat the Oven: Start by preheating your oven to 350°F. Prepare your cookie sheet(s) by lining them with parchment paper or spraying them with nonstick cooking spray.
Mix the Eggs and Sugars: In a large mixing bowl (using an electric mixer or a stand mixer with a paddle attachment), combine 3 large eggs, 1¼ cups packed light brown sugar, and 1 cup granulated sugar. Beat on medium-high speed for about 1-2 minutes until thoroughly mixed.
Add Peanut Butter and Butter: Incorporate ½ cup softened salted butter and 1½ cups creamy peanut butter, along with 2 teaspoons baking soda, 1 teaspoon vanilla extract, and ½ teaspoon salt. Beat again until combined.
Mix in Oats and Chocolates: Gradually add 4½ cups quick oats, 1 cup miniature semi-sweet chocolate chips, and 1 cup mini M&M’s. Mix on low speed, scraping the bowl’s sides and bottom as needed to ensure everything is blended well.
Scoop the Dough: Use a 2-tablespoon cookie scoop to portion out the dough and drop the balls onto the prepared cookie sheet, spacing them apart (you’ll fit about 12 cookies per sheet).
Bake the Cookies: Place the cookie sheet in the oven and bake for 7-9 minutes. The cookies should look soft and slightly underbaked when you take them out, with just a light golden hue. Remember, they’ll continue to firm up as they cool.
Cool and Decorate: Remove the cookies from the oven, letting them stay on the warm cookie sheet for about 20 minutes before transferring them to a cooling rack. For an extra touch, gently press some additional M&M’s on top while still warm to make them pop!
Enjoy: Indulge in these treats warm or at room temperature. Trust me, you won’t be able to resist!

Storing & Reheating

To keep your No Flour Monster Cookies at their best, store them at room temperature in an airtight container for up to one week. If you want them to last longer, consider refrigerating them for two weeks. For an extended shelf life, you can freeze these cookies for up to three months! Just place them in a freezer-safe container, separating layers with parchment paper. When you’re ready to enjoy, pop them in the microwave for about 10-15 seconds to warm them up — they’ll taste like freshly baked cookies!

Chef’s Helpful Tips

Avoid Overmixing: When combining the oat mixture, mix just until the ingredients are combined to keep your cookies chewy.
Keep Ingredients at Room Temperature: Make sure your eggs and butter are both at room temperature for easy mixing.
Check Oat Consistency: Ensure you’re using quick oats for the right texture. Regular oats will create a different consistency.
Adjust Bake Time: Ovens can vary in temperature, so monitor your cookies closely — they should look slightly underbaked when removed from the oven.
Experiment with Mix-Ins: Feel free to add your favorite nuts, dried fruits, or even a splash of flavored extract to make these cookies your own!

No Flour Monster Cookies are not just a treat; they’re an experience. They blend flavors that complement each other beautifully and provide a satisfying chewiness that’s hard to match. With every bite, you’re hit with the nutty richness of peanut butter balanced by the sweetness of chocolate and candy. Whether you’re baking for a crowd or just yourself, these cookies are bound to become a new favorite in your kitchen.

Recipe FAQs

Can I use natural peanut butter instead of creamy?

Absolutely! Natural peanut butter will give you a different texture and flavor, but it will still work well in this recipe. Just ensure it’s well stirred before measuring to get the right consistency.

How do I know when the cookies are done?

Since these cookies don’t spread much, it can be tricky. Focus on their appearance: they should look soft and slightly underbaked, with a very light golden color. They’ll firm up as they cool.

Can this recipe be made ahead of time?

Yes! You can prepare the dough in advance and refrigerate it for up to three days before baking, or freeze the dough for up to three months. Just let it thaw in the fridge before baking.

Are these cookies gluten-free?

Yes! These No Flour Monster Cookies are gluten-free as long as you use certified gluten-free oats. It’s a fantastic choice for those with gluten sensitivities.
