Ingredients You’ll Need

Each ingredient in The BEST Chewy Monster Cookies Recipe plays an important role in building those chewy, flavorful cookies you’ll crave. From oats that add hearty texture to peanut butter for richness, here’s what you want to pick up next time you shop.

• All-purpose flour: The base that holds everything together and gives structure to your cookie.
• Baking soda: Helps with leavening and gives a slight lift so cookies aren’t too dense.
• Baking powder: Works alongside baking soda for extra rise and tenderness.
• Salt: Enhances all the flavors so the sweetness doesn’t feel one-dimensional.
• Unsalted butter: Softened is key—it creams better with sugar for that silky dough texture.
• Light brown sugar: Adds moisture and caramel-like depth to keep the cookie chewy.
• Peanut butter: Use smooth peanut butter for that signature nutty flavor and additional chewiness.
• Honey: Just a touch to balance sweetness and keep the cookies soft.
• Egg: Room temperature eggs blend evenly into the dough, giving moisture and binding the ingredients.
• Pure vanilla extract: Boosts the sweetness and rounds out the flavors beautifully.
• Rolled oats (large flake): These add great texture and a wholesome bite without overpowering.
• Dark chocolate chunks: Melty, rich chocolate that pools in every bite, making these cookies irresistible.
• Regular M&M’s: These bring color and candy crunch, plus a little extra sweet fun.
• Mini M&M’s: Great for distributing smaller bursts of candy in each cookie evenly.

Variations

One of the best parts about The BEST Chewy Monster Cookies Recipe is how easy it is to adapt and make your own. I like to switch things up depending on the season or what my family is craving, and you’ll enjoy playing around with these simple twists too.

• Nut-Free Version: Replace peanut butter with sunflower seed butter, and swap M&M’s for allergy-friendly candy pieces — my nephew loves this twist!
• Double Chocolate Monster: Add cocoa powder to the dry mix and use white chocolate chunks instead of dark for an intense chocolate lover’s dream.
• Healthy Boost: Throw in chopped nuts or dried cranberries along with the oats for extra texture and nutrition. I do this when I want a slightly more wholesome snack.
• Seasonal Mix-Ins: Try festive candies or peppermint chips around holidays — my friends are always impressed by this simple upgrade.

How to Make The BEST Chewy Monster Cookies Recipe

Step 1: Mix the Dry Ingredients

Start by whisking together your flour, baking soda, baking powder, and salt in a medium bowl. This might seem basic, but it’s so important to get these evenly blended so your cookies rise and bake just right. I always whisk for about 20 seconds until everything looks uniform—no clumps or streaks!

Step 2: Cream Butter and Sugar

In a large bowl, combine the softened unsalted butter and light brown sugar. Use a sturdy spatula or a hand mixer to “cream” these together until the mixture is smooth, even, and just a little fluffy. I’ve learned that creaming them well is key to that chewy texture, so don’t rush this step—you want the mix to look like wet, fluffy sand.

Step 3: Add the Peanut Butter, Honey, Egg, and Vanilla

Next, stir in smooth peanut butter and honey until fully combined. Then, add the egg (make sure it’s room temp!) and vanilla extract. Mix until everything is nicely incorporated. This mixture smells so good here—I sometimes stop and just breathe it in before moving on!

Step 4: Incorporate the Oats and Dry Mixture

Fold in the oats gently—this is what gives each cookie that hearty texture. Then, slowly add the flour mixture from Step 1, folding it just until combined. You don’t want to overmix here or your cookies will turn out tough. I usually fold just 20 times or so, stopping as soon as the flour disappears.

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

Finally, fold in the dark chocolate chunks and both types of M&M’s evenly. This step turns your dough into a colorful, chocolate-packed masterpiece. I love to sneak a few more chunks into the top of each ball before baking for chocolates to melt on the COOKIE’S surface.

Step 6: Chill the Dough

Cover the dough tightly with plastic wrap, pressing it right onto the surface to prevent a skin from forming, and refrigerate for 30 minutes. This chilling step is a game-changer—I learned it prevents cookies from spreading too much and helps keep that chewy texture you want.

Step 7: Bake to Perfection

Preheat your oven to 350°F and line two cookie sheets with parchment paper. Scoop about 2 tablespoons of dough and roll it gently into balls. Place the dough balls on your baking sheets, spacing them at least 2 inches apart so they don’t stick together during baking. Bake for 10-12 minutes, watching for the edges to turn a delicate golden color while the centers remain soft—they’ll firm up as they cool.

Step 8: Cool and Enjoy

After baking, let the cookies cool on the baking sheets for one minute, then carefully transfer them to a wire rack to cool completely. This helps keep the bottoms from getting soggy. And then, well… get ready for a seriously satisfying treat that you’ll want to bake again and again.

How to Serve The BEST Chewy Monster Cookies Recipe

Garnishes

Honestly, these monster cookies are so vibrant and packed with candy, I typically serve them as is—no fancy garnishes needed. But if I’m feeling playful, I sometimes sprinkle a tiny pinch of flaky sea salt on top right after baking; it balances the sweetness beautifully and takes each bite to a new level.

Side Dishes

Milk is my go-to side when serving these cookies—whether cold, almond, or oat milk, it pairs wonderfully to soften the richness. For special brunches, I love serving the cookies alongside fresh fruit or a simple yogurt parfait as a fun sweet conclusion.

Creative Ways to Present

For birthday parties or holiday gatherings, I arrange these colorful monster cookies on a large platter lined with parchment and decorate with extra M&M’s and chocolate chunks scattered around. I once packaged them individually in clear cellophane bags tied with festive ribbons and they made perfect edible favors!

Make Ahead and Storage

Storing Leftovers

After letting the cookies cool completely, I store them in an airtight container at room temperature. They stay wonderfully chewy for up to 4 days this way. If you love that fresh-baked texture, I suggest warming them slightly before enjoying leftovers.

Freezing

I freeze extra dough balls on a parchment-lined tray, then pop them into a freezer bag once solid. This makes it easy to bake fresh cookies whenever the craving hits. You can also freeze baked cookies wrapped tightly—just thaw at room temp or warm gently before serving.

Reheating

To bring leftover cookies back to life, I like to microwave one on a plate for 10-15 seconds or place them in a preheated 300°F oven for about 5 minutes. This melts the chocolate slightly and restores softness without drying them out.
