Rebecca’s Recipe Review: A Deep Dive into Monster Cookie Perfection
Our goal was to create a monster cookie that not only satisfies but truly delights, blending classic comforts with elevated bakery-style quality. Here’s a detailed breakdown of what makes this recipe stand out:
Taste: Prepare your palate for an exquisite dance of flavors—sweetness from the chocolates and M&Ms, perfectly balanced by the subtle savory notes of peanut butter, and a final burst of salty goodness from the flaky sea salt. This combination creates a rich and complex profile that is utterly addictive.
Texture: These are no ordinary cookies. They boast a distinctly thick and substantial form, with a delightfully slightly crunchy exterior that gives way to an incredibly chewy and soft interior. This textural masterpiece is further enhanced by the generous addition of rolled oats and various chocolate mix-ins, providing a satisfying mouthfeel with every bite.
Ease: We’ve rated this recipe at 4/10 in terms of ease. While it’s not overly complicated, the crucial dough chilling step adds to the overall preparation time. However, don’t let this deter you; the simple steps and the incredible outcome make the effort entirely worthwhile.
Pros: The biggest advantage of these cookies is their unparalleled big flavor! Each ingredient contributes to a harmonious and bold taste profile that sets them apart from typical homemade cookies. They truly deliver a gourmet experience right from your oven.
Cons: The primary drawback, as mentioned, is the required chill time for the dough. This step is non-negotiable for achieving the perfect texture and preventing excessive spreading, but it does mean you need to plan ahead. Patience is a virtue when baking these beauties!
Would I Make This Again? Absolutely, without a doubt! Monster Cookies are a cherished favorite in our household, and this perfected recipe ensures they will remain a staple for years to come. Once you try them, you’ll understand why they’re so irresistible!

Essential Ingredients for Perfect Monster Cookies
Crafting the perfect Monster Cookie requires a thoughtful selection of ingredients, each playing a vital role in achieving that signature bakery-style texture and rich flavor. Our recipe strategically combines specific flours and starches to create an unparalleled cookie base.
The foundation of these exceptional cookies lies in a precise blend of cake flour, all-purpose flour, corn starch, and hearty rolled oats. Cake flour is key for its low protein content, which contributes to an incredibly tender crumb, while corn starch works wonders to enhance the cookies’ softness and chewiness, preventing them from becoming dry or crumbly. The rolled oats not only add a delightful chew but also a wholesome texture that defines a classic monster cookie.
Beyond this unique flour blend, we incorporate standard baking essentials to build a robust flavor profile. These include reliable leavening agents like baking soda, a combination of light brown sugar and granulated sugar for balanced sweetness and moisture, a touch of salt to enhance all flavors, plump large eggs and additional large egg yolks for richness and binding, creamy salted butter (always cold!), and a generous splash of pure vanilla extract for aromatic depth.
To truly elevate these cookies, we’ve incorporated a secret ingredient: malted milk powder. This addition creates a delicious depth of flavor, introducing subtle, toasty, and caramel notes that make these cookies truly unforgettable. While it significantly boosts the flavor experience, malted milk powder primarily impacts taste, not structure, so you can choose to omit it if it’s not readily available, though we highly recommend it for that extra special touch.
And of course, it wouldn’t be a Monster Cookie without the spectacular add-ins! Our recipe calls for a generous mix of colorful M&Ms, rich chopped milk chocolate for varied melting textures, and classic semi-sweet chocolate chips to ensure chocolatey goodness in every bite. To perfectly balance the inherent sweetness of these ingredients, we recommend sprinkling flaky sea salt on top of each cookie before baking—this small touch creates an incredible sweet-and-salty contrast.
Feel free to customize the add-ins to your preference! If there’s an ingredient you don’t particularly enjoy, you can easily leave it out or substitute it with another favorite cookie mix-in, such as white chocolate chips, butterscotch chips, or chopped nuts. The beauty of a “monster” cookie is its versatility!

Step-by-Step Guide: How to Make Irresistible Monster Cookies
Creating these sensational Monster Cookies is a rewarding process. Follow these detailed steps to ensure a perfect batch every time:
- Combine Dry Ingredients: In a medium-sized bowl, meticulously whisk together the cake flour, all-purpose flour, rolled oats, malted milk powder (if using), corn starch, and baking soda. Ensure these dry ingredients are thoroughly combined to distribute them evenly throughout the dough. Set this bowl aside for later use.
- Cream Wet Ingredients: In the bowl of a stand mixer fitted with a paddle attachment, combine the cold salted butter, light brown sugar, granulated sugar, peanut butter, and salt. Cream this mixture together at medium-high speed for approximately 3 to 4 minutes, until it becomes wonderfully smooth and light in color. Remember to pause and scrape down the sides of the bowl every minute or so to ensure all ingredients are fully incorporated.
- Incorporate Eggs and Vanilla: Once the butter mixture is smooth, add the large eggs one at a time, mixing well after each addition. Then, introduce the additional large egg yolks, followed by the vanilla extract, and mix until just combined. Be careful not to overmix at this stage.
- Blend Dry and Wet Mixtures: Gradually add the reserved dry ingredient mixture into the butter mixture, a little at a time. Mix on low speed until the dough just comes together and is smooth. Avoid overmixing once the flour is added, as this can lead to tough cookies.
- Fold in the Mix-ins: Gently fold in the M&Ms, chopped milk chocolate, and semi-sweet chocolate chips. Mix just until they are thoroughly combined and evenly distributed throughout the cookie dough. This ensures every cookie is packed with delicious surprises.
- Portion and Chill Dough: Using a kitchen scale for precision, portion out each ball of cookie dough to approximately 6 ounces. Roll them gently into uniform spheres and then transfer them onto a parchment-lined baking sheet. This chilling step is crucial, so place the baking sheet with the dough balls in the fridge for at least 2 hours.
- Prepare for Baking: Preheat your oven to a precise 425°F (yes, this temperature is intentional!). While the oven heats, retrieve two 12×17-inch baking sheets. Stack one on top of the other, and line the top sheet with fresh parchment paper. This double-layering technique is a vital tip to prevent the bottoms of your cookies from overbaking or burning, ensuring an even bake.
- Bake in Batches: Carefully transfer 4 chilled cookie dough balls onto the prepared double-layered baking sheet, leaving ample space between each cookie to allow for spreading. Sprinkle each dough ball generously with flaky sea salt before placing them in the preheated oven. Bake for approximately 9 to 11 minutes, or until the edges are golden brown and the centers are still slightly soft.
- Cool the Cookies: Once baked, remove the cookies from the oven. Allow them to cool on the baking pan for a few minutes; this allows them to set and firm up without breaking. Afterward, carefully transfer them to a wire rack to cool completely.
- Repeat for Remaining Batches: To maintain optimal baking conditions, place the top baking pan (now empty) into the freezer to chill quickly. While it chills, place a new pan on top of your original bottom pan and line it with fresh parchment paper. Bake the next batch of four cookies following the same process. Continue this rotation, using the chilled top pan for each subsequent batch, until all your Monster Cookies have been perfectly baked.

Rebecca’s Essential Monster Cookie Baking Tips
Achieving bakery-quality Monster Cookies involves a few key techniques. Here are my top tips to ensure your cookies turn out perfectly every time:
- Utilize a Stand Mixer: For this recipe, a stand mixer is highly recommended. Creaming cold butter, which is crucial for the cookie’s structure, can be incredibly difficult by hand. A stand mixer fitted with a paddle attachment will efficiently and thoroughly combine the ingredients, ensuring a smooth and consistent dough.
- Always Use Cold Butter: This is a non-negotiable tip! Using cold butter is fundamental for preventing the cookies from spreading too much during baking. Room temperature or melted butter would negatively impact the structure, resulting in flat, greasy cookies instead of the thick, chewy monsters we’re aiming for.
- Opt for Creamy Peanut Butter: Stick to creamy or regular peanut butter. Natural peanut butter, with its higher oil content and tendency to separate, can alter the dough’s consistency and negatively affect the overall taste and texture of the finished cookies. For best results, use a classic creamy variety.
- Customize Peanut Butter Flavor: If you’re a true peanut butter enthusiast and want to amplify that flavor, consider swapping out half of the M&Ms for an equal amount of Reese’s Pieces. This will infuse the cookies with an extra layer of nutty goodness.
- Precision in Portioning with a Kitchen Scale: For consistently sized and evenly baked cookies, it’s best to use a kitchen scale to portion out the dough into precise 6-ounce cookie balls. If you don’t have a scale, we’ve found that a Vollrath No. 8 Scoop often gets close to the 6-ounce mark, but always adjust by adding or removing a little dough as needed to hit the target weight. Consistent sizing is key for uniform baking.
- Double-Layer Your Baking Sheets: This technique is a baker’s secret weapon! Placing two baking sheets on top of each other creates an insulating layer. This prevents the direct heat from the oven from overbaking or burning the bottoms of your large cookies, ensuring they cook evenly and achieve that perfect golden hue without getting too dark.

Storing Your Delicious Monster Cookies
To keep your Monster Cookies fresh and delightful, ensure they have cooled completely after baking. Once cooled, transfer them into an airtight container. They will remain wonderfully soft and chewy at room temperature for up to 4 days. If you need to stack the cookies in a deeper container, we highly recommend placing a layer of parchment paper between each layer to prevent them from sticking together. This simple step preserves their perfect appearance and prevents any chocolate transfer.
Made the Monster cookies today. Very good and rich. I made them smaller but still a big cookie. I got 32 cookies out of the recipe. Definitely used your tip of 2 cookie sheets stacked to avoid burning.

How to Freeze Monster Cookies for Future Enjoyment
Planning ahead for a party, celebration, or a bake sale? Or simply want to have a homemade treat ready at a moment’s notice? Freezing these Monster Cookies, either as dough or after baking, is an excellent strategy. It allows you to get ahead of the rush and enjoy a fresh-baked cookie whenever the craving strikes!
Freezing Cookie Dough: Once you’ve portioned out the cookie dough balls onto a parchment-lined baking sheet, transfer the entire sheet to the freezer for at least one hour to flash freeze. This prevents the dough balls from sticking together. After they are firm, move the frozen dough balls into a heavy-duty freezer bag, ensuring you squeeze out as much excess air as possible to prevent freezer burn. The dough can be stored in the freezer for up to 3 months. When you’re ready to bake, remove the desired number of dough balls from the bag and thaw them in the refrigerator overnight. Then, bake as directed for 9 to 10 minutes, adjusting slightly for thickness and doneness.
To bake from frozen, simply place the dough balls on your prepared baking sheet and add a couple of extra minutes to the baking time, watching carefully for golden edges.
Freezing Baked Cookies: Allow your freshly baked Monster Cookies to cool completely on a wire rack. Then, arrange them on a baking sheet and flash freeze them for about 30 minutes. This step is important as it firms up the chocolate pieces and ensures the cookies won’t stick together. Once flash-frozen, transfer the cookies to a freezer bag, removing all excess air. They can be stored in the freezer for up to 3 months. To enjoy, simply thaw the cookies at room temperature for an hour or so, or for a warm, gooey treat, microwave them for about 15 seconds.

These big, chewy Monster Cookies are inspired by the cookie style of New York’s Levain Bakery and are loaded with M&Ms, chopped milk chocolate, and semi-sweet chocolate chips!
Ingredients
- 1½ cups cake flour (195g, spoon and leveled)
- 1½ cups all-purpose flour (195g, spooned and leveled)
- 1 cup rolled oats (100g)
- 1 tablespoon malted milk powder (10g)
- 1 tablespoon corn starch (8g)
- ½ teaspoon baking soda (6g)
- 1 cup cold salted butter (227g)
- 1⅓ cups light brown sugar (266g, packed)
- ½ cup granulated sugar (100g)
- ½ cup peanut butter (130g)
- 1¼ teaspoons salt
- 2 large eggs
- 3 additional large egg yolks
- 1 tablespoon vanilla extract
- 10 ounces M&Ms (284g)
- 8 ounces milk chocolate (250g, chopped)
- 1½ cups semi-sweet chocolate chips (260g)
- flaky sea salt for garnish
Instructions
- Whisk together the 1½ cups cake flour, 1½ cups all-purpose flour, 1 cup rolled oats, 1 tablespoon malted milk powder, 1 tablespoon corn starch, and ½ teaspoon baking soda in a medium bowl. Set aside.
- In a stand mixer fitted with a paddle attachment, cream together the 1 cup cold salted butter, 1⅓ cups light brown sugar, ½ cup granulated sugar, ½ cup peanut butter, and 1¼ teaspoons salt. Mix at medium-high speed until smooth, about 3 to 4 minutes, scraping down the sides of the bowl about every minute.
- Once combined, add in the 2 large eggs one at a time, followed by the 3 additional large egg yolks. Then, mix in 1 tablespoon vanilla extract.
- Once smooth, mix in the flour mixture a little at a time until smooth.
- Add in the 10 ounces M&Ms, 8 ounces milk chocolate, and 1½ cups semi-sweet chocolate chips. Mix just until combined.
- Weigh each dough ball out to 6oz and place on a parchment-lined baking sheet and refrigerate for at least 2 hours.
- Preheat the oven to 425°F (NOT A TYPO) and place two 12×17-inch baking sheets on top of each other. Line the top one with parchment paper. Double layering the baking sheets helps prevent the bottom of the cookies from overbaking.
- Add 4 cookies to the lined baking sheet and sprinkle with flaky sea salt and bake for 9 to 11 minutes.
- Allow them to set on the pan for a few minutes before transferring to a wire rack to cool.
- Place the first top pan in the freezer to chill, and place a new pan on top of the original bottom pan and line with parchment paper and bake the next four cookies. Rotate once more to bake the remaining 4 with the sheet from the freezer.

Notes
- Once baked and cooled, these cookies can be stored in an air-tight container for up to four days.
- Do not use room temperature or melted butter in these cookies – cold butter only.
- Feel free to use half M&M’s and half Reese’s Pieces for extra peanut butter flavor.
- To make sure the cookies are uniform in size, it’s best to use a kitchen scale. This is also the best way to ensure that your ingredient measurements are correct by using grams instead of cup measurements. This is our favorite kitchen scale.
- These cookies are 6 ounces each, and while a kitchen scale is necessary to ensure your weighted measurement is correct, the dough is fairly soft, and a cookie scoop will help portion it out and shape it. We used our Vollrath No.8 Scoop. Most scoops hit the 6-ounce mark, but we took away or added a little cookie dough if needed.
- I highly recommend using a stand mixer for this recipe instead of mixing by hand or with a hand mixer. Since this recipe uses cold butter, it is much more difficult to cream properly, so a stand mixer with a paddle attachment is the best way to get the job done.
- How To Freeze Dough: Portion the dough out onto a parchment-lined baking sheet (the balls can be close together) and flash freeze for 1 hour. Transfer to a freezer bag and remove any excess air and freeze for up to 3 months. Remove from the bag before thawing in the fridge, so the dough doesn’t stick to the bag. Bake for 9 to 10 minutes once thawed.
- How To Freeze Baked Cookies: Let the cookies cool completely after baking, then flash freeze for 30 minutes on a baking sheet to make sure the exterior bits of chocolate is firm and reduce the risk of making a mess. Transfer the cookies to a freezer bag and remove as much excess air as possible before freezing for up to 3 months. Thaw at room temperature a nuke in the microwave for 15 seconds before enjoying.
