Oh my goodness, these Cookie Monster Cookies are absolutely everything! If you love cookies as much as Cookie Monster loves his cookies, then this recipe is for you. These aren’t your average chocolate chip cookies – they’re loaded with THREE types of chocolate, oats, and all the delicious mix-ins that make them absolutely irresistible.
I first discovered Cookie Monster Cookies years ago and have been perfecting my version ever since. They’re thick, chewy, and loaded with so much goodness that one cookie is almost never enough (trust me, I’ve tried!). The secret to making the BEST Cookie Monster Cookies lies in using quality chocolate, not overbaking them, and getting that perfect balance of crispy edges and chewy centers.
These cookies are perfect for so many occasions – whether you’re baking for a school event, wanting to impress guests, or simply treating yourself to something sweet. They pair beautifully with a cold glass of milk or your favorite coffee. The recipe makes a generous batch, so you’ll have plenty to share (or keep all to yourself – no judgment here!).
What makes these cookies truly special is the combination of ingredients. We’re talking white chocolate chips, milk chocolate chips, dark chocolate chips, oats, and even some crushed cookies mixed right into the dough. It’s basically a cookie lover’s dream come true.

This is the kind of recipe that welcomes creativity and experimentation.

I love making these cookies on lazy Sunday afternoons or when I need a little pick-me-up during the week. The dough comes together quickly, and before you know it, you’ll have a batch of golden, chocolate-loaded cookies cooling on your counter. Your kitchen will smell absolutely amazing, and you’ll have cookies that rival any bakery.

Ingredients
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup (2 sticks) unsalted butter, softened
- 3/4 cup granulated sugar
- 3/4 cup packed brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 1/2 cups old-fashioned rolled oats
- 1 cup white chocolate chips
- 1 cup milk chocolate chips
- 1 cup dark chocolate chips
- 1 cup crushed chocolate sandwich cookies (like Oreos)
- 1/2 cup chopped walnuts or pecans (optional)
- 1/4 teaspoon cinnamon (optional)

Instructions
- Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats for easy cleanup and even baking.
- In a small bowl, whisk together the flour, baking soda, salt, and cinnamon if using. Set this dry mixture aside.
- In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 2-3 minutes. This step is crucial for creating that perfect cookie texture.
- Add the eggs one at a time to the butter mixture, beating well after each addition. Then add the vanilla extract and mix until everything is well combined.
- Gradually add the dry flour mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can make the cookies tough.
- Fold in the rolled oats using a wooden spoon or rubber spatula until evenly distributed throughout the dough.
- Add the white chocolate chips, milk chocolate chips, dark chocolate chips, and crushed chocolate cookies to the dough. Fold these in gently but thoroughly, making sure the mix-ins are evenly distributed throughout the cookie dough.
- If using nuts, fold them in at this point as well. Stir until you have a chunky, delicious-looking dough loaded with chocolate and cookies.
- Drop rounded tablespoons of dough onto your prepared baking sheets, spacing them about 2 inches apart since these cookies will spread as they bake.
- Bake for 12-14 minutes, until the edges are golden brown but the centers still look slightly underdone. This is the secret to getting that perfect chewy center with crispy edges.
- Remove the baking sheets from the oven and let the cookies cool on the pan for 5 minutes before transferring them to a wire cooling rack.
- Allow the cookies to cool completely on the rack before serving or storing. They will continue to set as they cool.
