How to Make Monster Cookies Recipe

Step 1: Prepare Your Baking Setup

First, preheat your oven to 350°F. Line two baking sheets with parchment paper or Silpat mats to ensure the cookies don’t stick and bake evenly. This little prep step saves you from sticky mishaps and guarantees hassle-free cleanup.

💡 Pro Tip: If you don’t have parchment, lightly greasing the pan is an alternative but may affect cookie bottoms slightly.

Step 2: Cream the Butter and Sugars

In your stand mixer fitted with the paddle attachment, beat together 1 cup sugar, 1 cup packed light brown sugar, and 1/2 cup unsalted butter. Cream the ingredients until the mixture is light, airy, and fluffy. This creates the perfect foundation for tender cookies.

💡 Pro Tip: Scrape down the sides of the bowl to ensure even mixing for consistent texture.

Step 3: Add the Eggs and Peanut Butter

Beat in the 3 large eggs, one at a time, to combine fully before adding the next. Then add 1 1/2 cups peanut butter, along with 1 tablespoon vanilla extract, 2 teaspoons baking soda, and 1/2 teaspoon salt. Mix until everything forms a smooth, uniform dough bursting with nutty promise.

💡 Pro Tip: Using creamy peanut butter will make your cookies smoother, but chunky adds delightful crunch.

Step 4: Incorporate the Oats and Mix-ins

Slowly fold in 4 1/2 cups oats, mixing just until combined. Finally, stir in 1 cup mini M&Ms and 1 cup mini chocolate chips. The dough will be thick and chunky, studded with colorful candies that hint at the delicious bites to come.

💡 Pro Tip: Reserve a handful of candies to gently press on top of each cookie before baking for a pretty presentation.

Step 5: Scoop and Bake

Using a cookie scoop or spoon, drop 2 to 3 tablespoon-sized mounds of dough onto the prepared baking sheets, leaving about 2 inches of space between each mound to allow spreading.

Bake for 12-15 minutes until the edges turn golden but the centers remain soft. Remove from the oven and let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

💡 Pro Tip: Don’t skip the cooling step on the sheet — this lets the cookies set perfectly without crumbling.

Common Mistakes to Avoid

Learn from these common pitfalls:

• Using cold butter: Leads to uneven mixing and dense cookies.
• Overbaking: Cookies will turn dry and lose that signature chewy texture.
• Skimping on baking soda: Can result in flat, overly dense cookies.
• Not spacing cookies properly: Causes them to bake into one large, misshapen mass.
• Overmixing oats: Can make dough tough and compromise chewiness.
• Ignoring cooling time: Cookies may break apart if transferred too early.

Reheating

Warm cookies in the oven at 300°F for 5-7 minutes to regain that fresh-baked softness, or microwave for 15-20 seconds for a quick fix.
