Ingredients You’ll Need
- Salted Butter (1 cup/2 sticks): The base of our cookies, providing delicious flavor and the right amount of moisture. Ensure it is softened for easy creaming.
- Brown Sugar (1 cup): This adds depth of flavor and moisture due to its molasses content, creating chewy cookies. Light brown sugar works just as well as dark.
- White Sugar (3/4 cup): For that signature sweetness and a slight crispiness on the edges.
- Peanut Butter (1 cup): The star ingredient! Choose creamy for smooth cookies or chunky for extra texture. Natural peanut butter can be used for a healthier twist, just make sure to stir it well!
- Eggs (2): These bind the cookies together and add moisture. Make sure they are at room temperature for better blending.
- Vanilla Extract (1 teaspoon): A hint of vanilla enhances all the flavors and adds warmth.
- Flour (1 ½ cups): Use all-purpose flour for the best results, but spoon and level it in the measuring cup for accuracy.
- Baking Soda (2 teaspoons): This leavening agent gives the cookies a lovely lift, making them soft and fluffy.
- Salt (1 teaspoon): Balances the sweetness of the cookies perfectly.
- Quick Oats (1 cup): These oats dissolve slightly as they bake, creating a chewy texture. Don’t substitute with rolled oats, as quick oats blend better.
- Old-Fashioned Oats (1/2 cup): This adds a hearty bite and chewiness.
- M&Ms (2 cups; plus more for topping): These chocolate candies provide color and sweetness. Feel free to mix it up with your favorite chocolate chips or peanut butter candies!
- Candy Eyes (optional): Add a playful touch, especially for festive occasions like Halloween!
How to Make Soft and Chewy Monster Cookies

Preheat and Prepare
Start by preheating your oven to 350°F. As the oven warms up, line two baking sheets with parchment paper or silicone baking mats which will ensure your cookies don’t stick and come out perfectly shaped. This little step not only saves you time but also makes the cleanup a breeze.
Beat the Butter
In a large mixing bowl or the bowl of your stand mixer, add the softened butter. Beat the butter for about two minutes on medium speed until it’s creamy and smooth. This aeration helps create a light texture in your cookies. Scrape down the sides and bottom of the bowl regularly to ensure an even mix.
Mix in Sugars and Peanut Butter
Now it’s time to combine the sugars. Add both the brown sugar and white sugar into the bowl along with the peanut butter. Beat this mixture until it’s well combined and fluffy. The sugars will dissolve into the butter, creating a gorgeous blend that screams “cookie!”
Add Eggs and Vanilla
Crack in the two room-temperature eggs, and pour in the vanilla extract. Continue to beat the mixture until everything is fully incorporated. As you mix, you’ll notice that lovely sweetness come alive. Don’t forget to scrape down the sides of the bowl again!
Combine Dry Ingredients
In a separate bowl, combine the flour, salt, and baking soda. Instead of adding this mixture directly, use a small spoon to stir it up gently before you add it to the wet ingredients. This ensures the baking soda and salt are evenly dispersed throughout your cookies. If you overmix at this stage, you risk dense cookies, so beat it in gently until you still see some flour streaks.
Fold in Oats and M&Ms
Next, add in the quick oats, old-fashioned oats, and M&Ms. Using a spatula or wooden spoon, carefully fold these in until just combined. It’s important not to over-mix, otherwise, you’ll end up with tough cookies instead of chewy wonders.
Chill Your Dough
Cover the mixing bowl with plastic wrap and stick it in the fridge for at least 1 hour, but you can let it chill for up to 3 hours or even overnight if you have the patience. Chilling helps the flavors meld and control spread while baking.
Bake Your Cookies
Once your dough is chilled, use a large cookie scoop to form 2-inch balls of dough and place them on the prepared baking sheets, leaving at least 2 inches between each. Bake in your preheated oven for about 10-12 minutes. You’ll know they’re done when the edges are firm, but the centers still appear slightly shiny. This indicates chewy perfection!
Top With Extra Treats
As soon as you pull the cookies from the oven, give them a festive touch by pressing additional M&Ms and a few candy eyes on top. If you want taller cookies, gently push the edges towards the center with the back of a spoon. It may feel a bit odd, but this helps create that thick, chewy cookie we all crave.
Cool and Enjoy
Let your cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. They’re best enjoyed warm, when the chocolate is melted and gooey. Just try to resist the temptation to eat more than one; that might be a challenge!
Tips for Success
- Butter Temperature: Make sure the butter is fully softened to room temperature. Cold butter won’t cream well, leading to denser cookies.
- Chill the Dough: Don’t skip this step! Chilling prevents the cookies from spreading too much, retaining that soft and chewy quality.
- Measuring Flour: Spoon and level the flour into your measuring cup for accuracy—too much flour can result in dry cookies.
- Don’t Overmix: When adding the flour and other dry ingredients, mix just until combined. Overmixing can lead to tough cookies.
- Add Ins: Feel free to mix up the M&Ms with other fun choc candies or nuts. Experimenting makes each batch unique!
Serve It With
Pair your Soft and Chewy Monster Cookies with a glass of cold milk or a rich cup of coffee for the perfect combination. Consider dusting them with a little powdered sugar or drizzling some melted chocolate on top for extra sweetness. These cookies make a delightful addition to any dessert table or are a fun treat to add to a lunchbox. They’re simply irresistible and will brighten up any gathering!
How To Store & Reheat Leftovers
To keep your cookies fresh, store them in an airtight container at room temperature for about a week. For longer storage, they can be refrigerated for up to two weeks. If you want to freeze them, simply place the baked cookies in a freezer-safe bag or container, layered with parchment paper, for up to 3 months. To enjoy them warm, reheat in the microwave for about 15-20 seconds. You can also pop them in a preheated oven at 350°F for about 5 minutes to refresh their texture.
Tips & Variations
How about mixing things up a bit? Here are some ideas:
- Flavor Swaps: Try using almond butter instead of peanut butter for a subtle twist in flavor.
- Gluten-Free Option: Substitute all-purpose flour with a 1:1 gluten-free flour blend.
- Seasonal Variations: Use seasonal candies (like pumpkin spice chips for fall) to give a festive flair.
- Texture Add-Ins: Incorporate chopped nuts or coconut flakes for a crunchy surprise.
Recipe FAQs
Can I use natural peanut butter?
Yes! Natural peanut butter works fine but be sure to stir it well before measuring as it separates. It may change the texture slightly, making it a bit crumblier.
Can I freeze the cookie dough?
Absolutely! You can scoop out the dough and flash freeze the cookie balls. Once frozen, store them in a zippered bag for up to 3 months. Bake from frozen, adding an extra minute or two to the baking time.
Why are my cookies flat?
If your cookies are coming out flat, it may be due to the butter being too warm or not enough flour. Make sure the dough is chilled enough before baking.
How do I get thicker cookies?
Chilling the dough is essential for thicker cookies. You can also try adding a tablespoon or two more flour or reduce the sugar slightly to keep them from spreading too much.
Baking Soft and Chewy Monster Cookies can be a delightful experience that everyone in the family will cherish.
