Ingredients You’ll Need

Every ingredient in The BEST Chewy Monster Cookies Recipe plays a key role in creating that perfect balance of chewy softness, rich flavor, and fun texture. I always recommend using fresh, quality ingredients for best results—especially with things like peanut butter and chocolate chunks.

• All-purpose flour: The sturdy base that holds the cookie together, choose unbleached if you can for a better flavor.
• Baking soda and baking powder: Both help with just the right rise and texture, so don’t skip either.
• Salt: Balances sweetness and enhances the overall flavor.
• Unsalted butter: Softened to room temperature for easy creaming — this adds richness and moisture.
• Light brown sugar: Adds sweetness and a subtle caramel depth that works beautifully in chewy cookies.
• Peanut butter: Smooth and creamy, it gives these cookies their signature flavor and chewiness.
• Honey: Just a touch to add natural sweetness and help keep the cookies moist.
• Large egg: At room temperature, it binds everything and ensures even texture.
• Pure vanilla extract: A splash to brighten and deepen the cookie flavor.
• Large flake rolled oats: Adds chew and a wholesome touch — make sure you use rolled oats, not instant.
• Dark chocolate chunks: Melty pockets of rich chocolate that contrast perfectly with the peanut butter.
• M&M’s (regular and mini): For fun bursts of color and crunchy candy coating that kids adore.

Variations

I love encouraging you to make The BEST Chewy Monster Cookies Recipe your own. Over the years, I’ve played around with all kinds of variations that keep this recipe feeling fresh and exciting—without losing that signature chewiness we all crave.

• Nut-free version: Swap the peanut butter for sunflower seed butter or a mild almond butter for allergy-friendly alternatives that don’t skimp on flavor.
• Mix-ins galore: Try swapping M&M’s with raisins, chopped nuts, or white chocolate chips depending on what you have or your preferences—I personally adore adding chopped walnuts for a little extra crunch!
• Healthier twist: Substitute half the all-purpose flour with whole wheat flour and use a bit less sugar to create a slightly more wholesome cookie that still satisfies your sweet tooth.
• Seasonal flavors: During holidays, I sometimes add a sprinkle of cinnamon or swap honey for maple syrup for a warm seasonal touch.

How to Make The BEST Chewy Monster Cookies Recipe

Step 1: Whisk Together the Dry Ingredients

Start by combining your flour, baking soda, baking powder, and salt in a medium bowl. Give it a good whisk to evenly mix everything together. This step helps make sure your leavening agents are spread throughout the dough, so your cookies bake evenly without any unexpected fluff or flat spots.

Step 2: Cream Butter, Sugar, and Peanut Butter

In a large bowl, take your softened unsalted butter and brown sugar and use a spatula or mixer to cream them together until the mixture looks smooth, fluffy, and slightly lighter in color—kind of like wet sand. Then mix in the peanut butter, followed by the honey. This combination creates that luscious, super chewy texture you’re craving!

Step 3: Add Egg and Vanilla

Next, add in the egg (make sure it’s at room temp to avoid curdling) and vanilla extract. Mix just until combined; don’t overbeat. This ensures a tender cookie, so keeping that gentle touch helps maintain a chewy texture later.

Step 4: Stir in Oats and Fold in Dry Ingredients

Now fold in the oats—it adds that great chew and heartiness. Then add the dry flour mixture you whisked earlier, folding it gently just until you don’t see any streaks of flour. Overmixing here can make your cookies tough, so take it slow!

Step 5: Mix in the Chocolate and M&M’s

This is the fun part! Fold the dark chocolate chunks and both sizes of M&M’s right into the dough. They’ll spread throughout the cookies, giving you colorful pockets of sweetness and melty, gooey chocolate in every bite.

Step 6: Chill the Dough

Cover the bowl tightly with plastic wrap, pressing it directly onto the dough’s surface, then pop it into the fridge for 30 minutes. Chilling firms up the dough, which helps prevent the cookies from spreading too thin and keeps them nice and chewy.

Step 7: Scoop and Bake

Preheat your oven to 350°F (175°C) and line two cookie sheets with parchment paper. Use about 2 tablespoons of dough per cookie, rolling it into balls and spacing them at least 2 inches apart. Bake for 10-12 minutes. The edges should be lightly golden while the centers still look soft—resist the urge to over-bake! They’ll set perfectly as they cool.

Step 8: Cool and Enjoy

Let the cookies cool on the baking sheet for about 1 minute before carefully transferring them to a wire rack to cool completely. Trust me, trying to move them too soon can lead to breakage. And if you can’t wait—warm, fresh-out-of-the-oven monster cookies are downright irresistible!

How to Serve The BEST Chewy Monster Cookies Recipe

Garnishes

I usually keep it simple here but sometimes sprinkle a few extra mini M&M’s on top right after scooping the dough onto the baking sheet—it gives a little fancy pop that kids go crazy for. For a grown-up twist, a tiny sprinkle of sea salt right after baking really elevates the chocolate and peanut butter flavors.

Side Dishes

These cookies are fantastic on their own, but for a fun dessert platter, I like to serve them alongside cold milk or a scoop of vanilla ice cream. They’re also perfect paired with a warm cup of coffee or tea when you need a cozy afternoon pick-me-up.

Creative Ways to Present

For birthday parties or special occasions, I’ve arranged these cookies on a colorful platter lined with parchment paper and sprinkled some edible glitter or drizzled melted white chocolate over them for a playful look. You can also package them in small cellophane bags tied with a cute ribbon for easy gifting—it’s always a hit!

Make Ahead and Storage

Storing Leftovers

I store leftover monster cookies in an airtight container at room temperature to keep them chewy for up to 4-5 days. If your kitchen is warm, I recommend storing them in the fridge to avoid melty chocolate and preserving freshness, but be mindful that refrigeration can slightly firm up the texture.

Freezing

Freezing these cookies works great! I like to freeze the dough balls on a baking sheet first, then transfer them to a freezer-safe bag. That way, you can bake fresh cookies straight from frozen whenever a craving hits, just add an extra couple minutes to the bake time.

Reheating

To warm up leftover cookies, I pop them in the microwave for about 10-15 seconds or briefly in a low oven (around 300°F). This refreshes that gooey melty center and restores the fresh-baked magic. Just don’t overheat or they’ll lose their chewiness.
