Recipe preparation

Essential Ingredients

Here’s what you’ll need to make this delicious dish:

  • All-Purpose Flour: Use regular flour for the best texture in your cookies—no fancy stuff needed here!
  • Rolled Oats: Choose old-fashioned oats; they provide great texture without making the cookies too chewy.
  • Baking Soda: This is your leavening agent; it helps create those perfectly puffy cookies.
  • Salt: Just a pinch enhances all the flavors beautifully; don’t skip it!
  • Unsalted Butter: Softened butter gives these cookies that melt-in-your-mouth consistency; always use unsalted for better control over saltiness.
  • Brown Sugar: It adds moisture and depth of flavor—go for light brown sugar for a subtle caramel note.
  • Granulated Sugar: This helps sweeten things up—balance is key!
  • Eggs: One large egg binds everything together; use room temperature eggs for better integration.
  • Vanilla Extract: A splash adds warmth and richness to your cookie dough.
  • Chocolate Chips: Semi-sweet or milk chocolate chips work perfectly here—choose your favorite!
  • M&Ms: Colorful candies add fun and crunch; mix them up for variety.
  • Peanut Butter Chips (optional): For those who want an extra peanut-y kick!

The full ingredients list, including measurements, is provided in the recipe card directly below.

Let’s Make it Together

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. You want those cookies perfectly baked without sticking—trust me on this one.

Mix the Dry Ingredients: In a large bowl, whisk together flour, rolled oats, baking soda, and salt until combined. Set aside so they can mingle like old friends.

Cream Butter and Sugars: In another bowl, beat softened butter with brown sugar and granulated sugar until light and fluffy—about 3 minutes. You’ll know it’s ready when it looks like fluffy clouds!

Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated. Your mixture should smell heavenly by now!

Add Dry Ingredients Gradually: Slowly mix in the dry ingredients until just combined; avoid over-mixing unless you want tough cookies (and who wants that?).

Add Chocolate Chips & M&Ms: Gently fold in chocolate chips and M&Ms using a spatula so they’re evenly distributed throughout the dough.

Scoop & Bake: Using a tablespoon or ice cream scoop, drop generous amounts of dough onto prepared baking sheets spaced apart (they spread!). Bake for 10-12 minutes or until edges are golden but centers remain soft.

Allow them to cool slightly on the sheet before transferring to wire racks to cool completely. Watch them disappear faster than you can say “Best Monster Cookies Recipe!”

Enjoy these delightful treats warm or at room temperature—either way, they’re sure to be a hit at any gathering or simply as a cozy treat on your couch while binge-watching your favorite show!
