These bright blue Cookie Monster cookies are loaded with chunks of crushed cookies, chocolate chips, and white chocolate chips then they get stuffed with more cookies (because you can never have enough cookies). They’re big, soft, and chewy, with a little crunch from the cookie pieces.

Named after that friendly, blue Sesame Street monster, these famous Cookie Monster cookies were initially seen on TikTok and went viral.

We made our own version and added crushed Oreo and Chips Ahoy cookies to the batter. Instead of stuffing the cookies with milk chocolate, we stuffed them with a whole Oreo cookie and then topped them off with candy eyeballs. I’m pretty sure the Cookie Monster would approve.

These cookies are the perfect sweet treat for serving at themed birthday parties or Halloween celebrations. Serve them along with our Cookie Monster ice cream to really get into the Sesame Street spirit!

Why This Recipe Works

Bread flour makes the cookies thick, chewy, and soft due to the higher protein content (but the recipe also works with all-purpose flour if that is all you have).
Stuffing the cookies with an Oreo cookie makes them monster-sized, but you can make smaller ones if you stuff them with mini Oreo cookies.
Adding crushed Oreo and Chips Ahoy cookies to the batter gives them a fun twist.
These Sesame Street character-themed chocolate chip cookies will be a hit with kids and adults alike!
Using gel food coloring gives the cookies a more brilliant blue color than regular food coloring.

Ingredients Needed

Here is a list of the ingredients you will need for these blue monster cookies. Scroll down to the printable recipe card for all the details.

Butter. You can use salted or unsalted butter. The small amount of salt in salted butter does not affect the flavor of the cookies.
Brown sugar. The brown sugar helps make moist, chewy cookies.
Granulated sugar.
Vanilla extract.
Eggs. Let the eggs come to room temperature.
Royal blue gel food coloring. If you use regular blue food coloring, you will need twice as much.
Bread flour. Bread flour has a higher protein content and gives the cookies a thick, dense texture. If you don’t have bread flour, you can use regular flour.
Baking powder and baking soda. Make sure these leavening agents are not expired.
Salt.
Crushed cookies. We used store-bought cookies, but you can use homemade cookies as well. Our crispy chocolate cookies or our gluten-free peanut butter cookies would be delicious.
Chocolate chips. We used a combination of white chocolate chips and milk chocolate chips, but semi-sweet chocolate chips make delicious cookies as well.
Milk chocolate bars. The video that went viral on TikTok had the cookies stuffed with chocolate.
Whole cookies. We stuffed the Monster Cookies with more cookies. Some suggestions are Oreos, Chips Ahoy, Nutter Butters, or Samoa cookies.
Candy eyeballs. The best part is making the cookies look like little monsters with candy eyeballs (just like our black cocoa cookies).

How to Make Stuffed Cookie Monster Cookies

Here is a brief overview to give you an idea of what to expect when making our cookie monster cookies. Scroll down to the printable recipe card for all the details.

Use an electric mixer to beat the softened butter, sugars, and vanilla extract together in a large bowl.
Add the eggs one at a time and incorporate them into the cookie dough mix.
Next, mix in your food coloring and sift in the dry ingredients (no need to use a separate bowl if you have a sifter).
Stir the dough on low speed until all the ingredients thoroughly combine.
Remove the mixing bowl and use a rubber spatula to fold in the crushed cookies and chocolate chips.
Use a large cookie scoop to make a dozen cookie dough balls.
Press a square of milk chocolate or a whole cookie into the center of each cookie, then add more cookie dough on top to cover the filling.
Pinch the edges of the cookies to ensure they have a tight seal, then press candy eyeballs and extra chocolate chip cookie pieces on top.
Chill your cookies in a fridge for at least three hours.
Line baking sheets with parchment paper and bake.
Allow the cookies to cool on the baking sheet for at least ten minutes, then transfer them to a cooling rack.

Tips for Success

Use bread flour instead of all-purpose flour if you want a denser, chewier cookie.
A #30 cookie scoop (which holds about two tablespoons) is what we used to measure each Cookie Monster cookie.
Gel food coloring is more concentrated than liquid food coloring. You can find gel food coloring from Joann’s in the cake decorating aisle.
If you only have liquid food coloring, use twice the amount to give the cookies the perfect blue color.
If you’re looking for an all-natural food coloring alternative, try Butterfly Pea Flower powder. It will make blue dough without using artificial coloring.
You can store the raw cookie dough mix in the fridge for up to a week before baking the cookies.
Store the cookies in an airtight container.
These are thick cookies, so the bake time is a little longer than standard recipes (plus, the larger cookies will need to bake significantly longer).
You can use a hand mixer or a stand mixer with a paddle attachment.

Ingredients

½ cup butter softened
½ cup packed brown sugar 105 grams
½ cup granulated sugar 100 grams
2 teaspoons vanilla extract
2 eggs
½ teaspoon Royal Blue gel food coloring
2-⅓ cups bread flour or all-purpose flour 280 grams
1-¾ teaspoons baking pow der
1 teaspoon baking soda
1 teaspoon salt
1 cup crushed cookies I used Oreos and Chips Ahoy
½ cup white chocolate chips
½ cup milk chocolate chips

Choose the Stuffing

2 milk chocolate bars cut into squares or
12 whole cookies Oreos, Samoas, Chips Ahoy

Topping

½ cup crushed cookies
Candy eyeballs

Instructions

Combine the butter, brown sugar, granulated sugar, and vanilla extract in a large mixing bowl. Beat on medium speed for about 6 to 8 minutes until soft and fluffy. Stop the motor and scrape down the bowl half way through the mixing time.
Add the eggs one at at time, mixing well between additions. Mix in the blue food coloring.
Stop the mixer. Place a metal sifter over the bowl and sift the flour baking powder, baking soda, and salt over the batter (alternatively, you can whisk the dry ingredients together in a separate bowl then stir it into the batter). Mix on low speed until well incorporated.
Stir in the crushed cookies and the white and milk chocolate chips.
Use a large cookie scoop (2 tablespoons) to scoop 12 balls of dough. Press the balls down and place a square of milk chocolate or a whole cookie in the center of the dough.
(You can make smaller cookies by using 1 tablespoon scoops and stuffing them with miniature cookies. We made both sizes in the video).
Scoop more cookie dough and place on top. Press the dough down and pinch the edges so the cookie or chocolate stuffing is completely covered. Press some additional crushed cookies and chocolate chips on top then add a couple of candy eyes to the top.
Place the dough balls in the refrigerator and let them chill for at least 3 hours.
Preheat the oven to 350°F and line a couple of baking sheets with parchment paper.
Arrange the stuffed cookies on the baking sheet, spacing them 2 inches apart.
When the oven is finished preheating, bake the cookies one tray at a time:10 to 12 minutes for the smaller cookies or 20 to 22 minutes for the larger cookies.
Let the cookies cool on the baking sheet for 10 minutes before transferring them to a cooling rack.

Notes

Bread flour will give the cookies a denser, thicker, chewier texture than all-purpose flour.

We used a #30 cookie scoop which holds approximately 2 tablespoons of cookie dough.

Gel food coloring is more concentrated than liquid food coloring, and you can find it online or at JoAnn’s Craft stores in the cake decorating section.
