Unsalted butter (1/2 cup, softened): Brings moisture and flavor depth, while ensuring the cookies stay soft and rich.
Creamy peanut butter (1/2 cup): Offers that classic monster cookie nuttiness and helps with chewiness.
Brown sugar (1/2 cup): Adds caramel-like sweetness and helps with the signature tenderness.
Granulated sugar (1/4 cup): Lends crisp edges and sweetness that balances the brown sugar.
Large egg (1): Binds everything together and adds softness.
Vanilla extract (1 teaspoon): Rounds out all the flavors with warmth and depth.
All-purpose flour (1 cup): Forms the structure—be sure to measure carefully for perfect cookies.
Baking soda (1/2 teaspoon): Gives just the right amount of lift for a soft and puffy texture.
Salt (1/4 teaspoon): Enhances flavor and balances the sweetness.

How to Make Soft Batch Monster Cookies

Step 1: Prep Your Oven and Baking Sheets

Start by bringing your kitchen up to temperature: preheat your oven to 350°F (175°C). While it warms, grab two baking sheets and line them with parchment paper—this not only prevents sticking but also helps those Soft Batch Monster Cookies slide off beautifully after baking.

Step 2: Cream Together the Wet Ingredients

In a large mixing bowl, combine the softened butter, creamy peanut butter, brown sugar, and granulated sugar. Use a hand mixer or stand mixer to whip it all together until the mixture is light and fluffy—this extra air makes the cookies pillowy soft. Add in the egg and vanilla extract, beating again until everything is wonderfully smooth and cohesive.

Step 3: Mix Your Dry Ingredients Separately

In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Taking this extra moment ensures the leavening and salt are evenly distributed—so every cookie bakes up just right.

Step 4: Combine Wet and Dry Mixtures

Gradually add your dry ingredients to the big bowl of wet ingredients, mixing just until incorporated. Don’t overmix—stop as soon as you see the flour disappear and the dough comes together. This is the secret to those unbeatable Soft Batch Monster Cookies, keeping them tender and moist.

Step 5: Stir in the Oats, Chocolate Chips, M&M’s, and Peanuts

Add your rolled oats, mini chocolate chips, mini M&M’s, and chopped peanuts (if using). Use a sturdy spatula and fold everything together; every scoop of dough should look colorful and chunky, with pops of chocolate and cheerful candy showing through.

Step 6: Scoop and Bake

Scoop the cookie dough into rounded tablespoons and arrange them about 2 inches apart on your prepared baking sheets. Space is crucial—they’ll spread a little, creating those glorious round edges. Bake for 9–11 minutes, just until the edges look barely golden. Resist the urge to overbake; the magic of Soft Batch Monster Cookies is in their underdone center!

Step 7: Cool and Enjoy

Let the cookies cool on the baking sheet for 5 minutes. They’ll finish setting up and get just enough structure to move without falling apart. Transfer to a wire rack to cool completely, and prepare to do the happiest taste test ever.

How to Serve Soft Batch Monster Cookies

Garnishes

To make your Soft Batch Monster Cookies extra festive, press a few extra mini M&M’s and chocolate chips onto the tops right after they come out of the oven. This trick gives bakery-style flair and bursts of color that make each cookie look irresistible.

Side Dishes

The classic partnership is a tall, cold glass of milk—absolutely dreamy with these chewy, chocolatey cookies. For an even more decadent treat, serve with a scoop of vanilla ice cream or alongside a creamy latte for a grown-up cookie break.

Creative Ways to Present

Make your Soft Batch Monster Cookies party-ready by stacking them in clear cookie jars, packaging them in colorful cellophane bags, or arranging them on a tiered dessert stand. They’re also fantastic for gifting: simply nestle a stack in a rustic tin or gift box tied with ribbon for a personalized touch.

Make Ahead and Storage

Storing Leftovers

Keep your Soft Batch Monster Cookies in an airtight container at room temperature; they’ll stay soft and fresh for up to 5 days. Be sure to let them cool completely before storing to prevent condensation that can make them soggy.

Freezing

Monster cookie dough is perfectly freezer-friendly! Scoop portions of dough onto a baking sheet, freeze until firm, then transfer to a freezer-safe bag. Bake from frozen (just add a minute or two to the bake time), or freeze the baked cookies—them thaw at room temp when a craving hits.

Reheating

If your cookies lose a bit of their gooey warmth, you can revive them in the microwave for about 10 seconds or in a 300°F (150°C) oven for just a couple of minutes. They’ll taste wonderfully soft and fresh, like they just came out of the oven.

FAQs

Can I use old-fashioned oats instead of quick oats?

Quick oats truly give the best chewy texture, but old-fashioned oats work in a pinch. Expect a heartier, more rustic cookie with a bit more bite.

Should I chill the dough before baking?

For this recipe, it isn’t necessary! The dough is thick enough to hold its shape, but if your kitchen is very warm, a 20-minute chill can help cookies bake extra thick and soft.

Can I omit the peanuts to make it nut-free?

Definitely! Leave out both the peanut butter and chopped peanuts, and swap in sunflower seed butter instead. The cookies will still be chewy and delicious with those signature pops of chocolate.

How do I keep my Soft Batch Monster Cookies chewy for days?

Store them in an airtight container with a slice of white bread. The bread gives up its moisture, which helps the cookies stay fresh and soft for longer.

What’s the best way to make these cookies gluten-free?

Try swapping the all-purpose flour for your favorite gluten-free baking blend, and make sure to use certified gluten-free oats. The result is just as chewy and colorful as the originals!

Final Thoughts

Every batch of Soft Batch Monster Cookies I pull out of the oven brings back joyful memories and makes new ones just as sweet.
