Gather Your Essential Ingredients for Gluten-Free Monster Cookies

Crafting these delectable monster cookies begins with a careful selection of ingredients. We’ve chosen a blend of pantry staples and delightful mix-ins to ensure perfect flavor and texture every time. Keep these on hand, and you’ll always be ready to whip up a batch!

• Gluten-Free Flour Blend: For superior results, we highly recommend King Arthur Measure For Measure Gluten-Free Flour. This blend is specifically formulated for a 1:1 substitution in most recipes and already contains xanthan gum, which is crucial for providing structure and elasticity in gluten-free baking. If you opt for a different 1:1 gluten-free flour, ensure it includes xanthan gum, or add it separately as directed on the packaging. For consistent baking, measuring flour by weight (grams) is always best. If you don’t have a kitchen scale, employ the scoop and level method to prevent over-packing the measuring cup, which can lead to dry, crumbly cookies.
• Certified Gluten-Free Oats: Oats provide that signature chewy texture in monster cookies. It’s vital to use certified gluten-free rolled oats (also known as old-fashioned oats) and gluten-free quick oats (or quick-cooking oats) to ensure they haven’t been cross-contaminated with wheat during processing. We love using a combination of both for an optimal texture, but you can use all rolled oats or all quick oats if preferred, keeping in mind the texture might vary slightly.
• Baking Powder & Baking Soda: These leavening agents work in tandem to give your cookies the perfect lift, spread, and a delightfully soft interior. Freshness is key for their effectiveness, so make sure yours aren’t expired.
• Salt: A touch of kosher salt enhances all the other flavors, balancing the sweetness and enriching the peanut butter and chocolate notes. If using fine table salt, you might want to use slightly less, as it’s saltier by volume.
• Unsalted Butter: Softened butter is absolutely essential for creaming with sugar, creating a light and airy base for the cookie dough. Make sure it’s at room temperature for optimal emulsification.
• Brown Sugar & Granulated Sugar: Our recipe uses a blend of light brown sugar and white granulated sugar. The brown sugar contributes to a moist, chewy cookie with a deeper, molasses-like flavor, while granulated sugar ensures the perfect crispness at the edges and helps with spread.
• Creamy Peanut Butter: This is a crucial ingredient for classic monster cookies. Opt for a traditional, smooth, and creamy peanut butter brand like JIF or Skippy. Avoid natural, drippy peanut butter varieties, as their oil separation and thinner consistency can cause the cookies to spread too much during baking and result in a drier, less desirable texture.
• Eggs & An Extra Egg Yolk: Using two large whole eggs plus an additional egg yolk is our secret for achieving an incredibly rich, chewy, and fudgy cookie texture. The extra yolk adds moisture and fat without adding extra liquid, resulting in a more tender crumb. Ensure your eggs are at room temperature for better incorporation into the dough.
• Vanilla Extract: A generous splash of pure vanilla extract is non-negotiable! It deepens the flavor profile of the cookies, adding warmth and complexity.
• Mini M&M Candies: While regular M&Ms work, we find that mini M&Ms are superior for monster cookies. Their smaller size allows for more uniform distribution throughout the dough, ensuring a burst of colorful chocolate in every bite, and they look fantastic both baked into and sprinkled on top of the cookies.
• Chocolate Chips (Regular & Mini): We use a combination of regular-sized semi-sweet chocolate chips within the dough for classic chocolate goodness, and then adorn the freshly baked cookies with extra mini chocolate chips. This not only adds more chocolatey flavor but also creates an appealing, professional finish. Dark chocolate chips are also a wonderful alternative for a richer flavor.

How to Make Perfect Gluten-Free Monster Cookies, Step by Step

Follow these detailed steps to bake your best batch of gluten-free monster cookies yet! For exact ingredient measurements and a printable version, refer to the full recipe card below.

1. Combine Dry Ingredients: In a medium-sized bowl, whisk together your gluten-free flour blend, certified gluten-free rolled oats, quick oats, baking powder, baking soda, and kosher salt. Whisk thoroughly for about 30 seconds to ensure all ingredients are evenly distributed and aerated. This prevents pockets of leavening agents and ensures a consistent texture. Set this bowl aside.
2. Cream Butter & Sugars: In the bowl of a stand mixer fitted with the paddle attachment (or using a large bowl with a handheld electric mixer), combine the softened unsalted butter, light brown sugar, and granulated sugar. Beat on medium speed for 2-3 minutes, or until the mixture becomes visibly light in color, fluffy, and creamy. This process incorporates air, which is vital for soft cookies. Remember to scrape down the sides of the bowl periodically to ensure everything is well combined.
3. Build the Dough Base: Add the creamy peanut butter to the butter-sugar mixture and beat until it’s fully incorporated and smooth. Next, add the large eggs one at a time, mixing well after each addition until just combined. Then, add the extra egg yolk and the vanilla extract. Scrape down the sides of the bowl once more to ensure no ingredients are clinging to the edges. Finally, gradually add the dry ingredients to the wet ingredients, mixing on low speed until just a few dry streaks or patches of flour remain. Be careful not to overmix at this stage, as it can lead to tough cookies.
4. Fold in the Mix-Ins: Gently add 1 ¼ cups of mini M&Ms and 1 ¼ cups of semi-sweet chocolate chips to the dough. Using a sturdy spatula, fold the mix-ins into the dough by hand. This gentle approach prevents the M&Ms from breaking or losing their color and ensures that all the delicious goodies are evenly distributed throughout every portion of the cookie dough.
5. Chill the Dough: Cover the bowl of cookie dough tightly with plastic wrap and place it in the refrigerator to chill for 30 minutes. This chilling period is crucial as it allows the gluten-free flour to fully hydrate, preventing the cookies from spreading too much during baking and enhancing their flavor and texture. While the dough chills, proceed to the next step.
6. Preheat Oven & Prep Baking Sheets: As your dough chills, preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper. This parchment paper prevents sticking and promotes even baking. Having two prepared sheets allows you to alternate them, ensuring you don’t place cool dough onto a hot baking sheet, which can negatively impact cookie spread.
7. Scoop & Roll: Working in batches of about 6 cookies at a time (to keep the remaining dough chilled), use a large cookie scoop (approximately 3-Tablespoon capacity) to portion out the cookie dough. Roll each scoop of dough smoothly between your palms to form a uniform ball. This helps create perfectly round cookies. Place 6 cookie dough balls onto one of your prepared baking sheets, ensuring they are spaced far enough apart to allow for spreading. Return the rest of the dough to the refrigerator between batches.
8. Bake to Perfection: Bake the cookies for 8-10 minutes. Look for cues: the edges should appear lightly set, but the centers should still look slightly soft and a bit underdone. Gluten-free cookies often don’t brown as much as traditional cookies, so rely on the setting of the edges. The residual heat on the cookie sheet will continue to cook the cookies as they cool, leading to that perfect soft and chewy texture. As soon as the cookies come out of the oven, immediately press a few extra mini M&Ms and mini chocolate chips onto the tops of each warm cookie. This creates a beautiful, “bakery-style” finish. Let the cookies cool on the baking sheet for 4-5 minutes before carefully transferring them to a wire rack to finish cooling completely. Repeat the baking process with the remaining dough, alternating baking sheets.
9. Serve & Store: Allow your delicious gluten-free monster cookies to cool completely for the best texture and flavor. Once cooled, enjoy them with a glass of milk! Store any leftover baked cookies in an airtight container at room temperature for 1-2 days, or for longer freshness, freeze them for up to 2 months.

Holiday Twists & Creative Variations

While our classic gluten-free monster cookies are perfect as is, they’re also incredibly versatile! Here are a few fun twists and variations to try when you’re looking to customize your batch for holidays or simply to explore new flavors:

• Halloween Monster Cookies: Transform these already “monster” cookies into spooky delights for Halloween! After they come out of the oven, press edible googly eye sprinkles onto the warm cookies. This simple addition creates a fun, whimsical, and perfectly themed treat for your spooky season gatherings.
• Christmas Monster Cookies: Spread some holiday cheer by making Christmas monster cookies. Simply swap out the regular M&Ms for festive red and green M&M candies. The vibrant colors will add a beautiful, joyful touch to your holiday cookie platters.
• Ultimate Peanut Butter Lover’s Cookies: If you’re a true peanut butter mega-fan, double down on that nutty flavor! Replace some or all of the semi-sweet chocolate chips with peanut butter chips. For an extra kick, use Reese’s Pieces instead of M&Ms (ensure they are gluten-free). This combination creates a cookie that’s almost as intensely peanut butter-packed as our popular Gluten-Free Reese’s Cookies.
• Nut-Free Monster Cookies: For those with peanut allergies, you can adapt this recipe! Substitute the peanut butter with a seed butter like sunflower seed butter (SunButter), ensuring it’s the creamy, traditional-style variety. Omit the peanut M&Ms and ensure all other mix-ins (chocolate chips, M&Ms) are certified nut-free.
• Add a Touch of Crunch: For extra texture, consider folding in a handful of chopped pecans or walnuts along with the M&Ms and chocolate chips. This adds another layer of flavor and crunch.
• White Chocolate Dream: Swap out some of the semi-sweet chocolate chips for white chocolate chips for a sweeter, creamier profile.
