Cookie Monster Cookies
These Cookie Monster Cookies are perfectly blue cookies packed with white chocolate chips, chopped chips ahoy cookies, and chopped Oreos.
Inspired by the Sesame Street character, Cookie Monster, these monster cookies are soft and chewy!
The Cookie Monster Cookies recipe was inspired by the beloved character from the classic children’s show Sesame Street. If your kids are cookie monster fans, this is the perfect recipe for birthday parties, school parties, or just for fun!
The cookies embody the bright and playful personality of Cookie Monster with their bright blue color and the fact that they are literally filled with more cookies. Yes, a cookie filled with cookies. Nothing is more cookie monster than that!
Making The Perfect Blue Cookie Monster Cookies
To achieve deep, cookie monster blue cookies, you will need quite a bit of gel food coloring. The first time I tested these, I only used royal blue and electric blue gel food coloring. The result was a teal-ish green cookie, not blue.
I learned from my friend Amy (who makes amazing raspberry chocolate chunk cookies, by the way), who learned from another blogger that adding violet gel food coloring to the batter really helps to achieve that true blue color. Purple and yellow are opposites on the color wheel, so purple helps to cancel out the yellow-brownish hues from the brown sugar and egg yolks, producing a brighter blue color!

How to Make Cookie Monster Cookies
It’s really a breeze to make these famous monster cookies! Find all the details for this easy recipe on the printable recipe card below.
Prep oven and cookie sheet. Preheat the oven to 350º F. Line a cookie sheet with a silicone baking mat or parchment paper.
Dry ingredients. In a mixing bowl, combine the flour, cornstarch, baking soda, and salt. Set aside.
Beat together. In a separate bowl, a larger mixing bowl, combine the butter, brown sugar, and granulated sugar. Beat on medium speed for 2 minutes. You want this mixture to be fluffy and pale in color.
Mix in wet ingredients. Add in the eggs and vanilla extract, and beat for 30 seconds.
Add food coloring. Gradually mix in the dry ingredients, mixing on low speed. Before you finish mixing the dough, add in the royal blue, electric blue, and violet gel food coloring. You will need a good bit of food coloring to achieve a deep, true blue color. Continue mixing, the dough will be thick.
Add additional ingredients. Add in ⅓ cup white chocolate chips, ⅓ cup chopped chips ahoy cookies, and ⅓ cup chopped oreos, and mix by hand until combined.
Form dough balls. Use a cookie scoop to form 2 tablespoon sized cookie dough balls, roll into a smooth ball between your hands. Make sure each ball is of equal portions. Press the remaining white chocolate chips, chips ahoy cookies, and oreo cookies on the outside of the dough balls. Place about 8 cookies on a cookie sheet lined with a silicone baking mat at a time. I recommend only baking 1 cookie sheet at a time for even baking. Bake 2 tablespoon sized cookie dough balls for 10-12 minutes. Ideally, you want to pull the cookies out of the oven before the edges start browning. Bake time may vary depending on your oven, so keep an eye on them.
Cool. Allow the cookies to cool for 15 minutes on the baking sheet before removing them or use a cooling rack.
Tips for the Best Monster Cookies
- Correctly measure the flour. I recommend weighing the flour on a food scale. However, if you don’t have a kitchen scale, use this method. First, fluff the flour with a fork. Then, use a spoon to scoop the flour into your measuring cup and use a butter knife to level the measuring cup. If you just stick the measuring cup straight into the bag of flour, it will result in too much flour being packed into the cup, which can result in dry cookies.
- Make sure the cookies don’t stick. If you don’t have a silicone baking mat or parchment paper, you can always use a lightly greased cookie sheet.
- Use the right food coloring. I recommend using gel food coloring only. Liquid food coloring will not produce the same blue color.
Substitutions & Variations
Cookie options: I used store-bought chips ahoy cookies, but you can use homemade chocolate chip cookies, or even peanut butter cookies would be tasty. Any kind of cookies you like would probably work.
Chocolate chips: I used white chocolate chips, but you can use a combination of white and milk chocolate chips, milk chocolate chips on their own or even semi-sweet chocolate chips would be good.
Add candy eyeballs: To make these easy cookie monster cookies even more fun for kids, add candy eyeballs! Just press them on top of the cookie dough balls before baking.
Add a chocolate center: For an even more indulgent cookie, use pieces of chocolate bars to fill the center of the cookie. Just form your dough ball around a small chunk of a chocolate bar before adding the outside toppings.
Storing and Freezing Cookie Monster Cookies
Store these cookies, after they have completely cooled, in an airtight container for up to 3 days. Store them in the fridge to get a couple more days out of them. You can also make this dough ahead of time and freeze the dough for up to 3 months. Just thaw completely before dividing it into balls and adding the outside toppings, then bake.

These cookies look so tempting, I would definitely like to try, but can you please tell me a substitute for eggs in the recipe
Hi Renu! I haven’t tested this recipe without eggs, so I can’t offer a substitute!
Applesauce has always worked wonders for me but haven’t tried it in this recipe
These cookies look amazing but are super dry, even with weighing flour. Salted butter would be better in them as well.
How many drops of food coloring for each of those colors do you recommend?
Gel food coloring is pretty thick, so it doesn’t really come out in nice drops, more like squirts! Maybe like 1/8 to 1/4 tsp of each?
Beth, you’re an inspiration! What a great idea! EVERYBODY knows Cookie Monster so these cookies would be a hit no matter where you serve them!
I would love to make these for my grandkids but I would have to order the food color gels and it was going to cost over $25 just for them. I’m sad now!!
Look at Walmart or Michaels for gel food coloring!
I can’t wait to try these! I’m going to make for my local Library Staff! They are so great!
How much of each food coloring do you add?
Maybe 1/8 to 1/4 tsp of each! But I didn’t measure, I just keep adding until I get the desired color.
About what size chunks of cookies are you putting in? Cutting in to 1/4 or 1/8?
Thank you so much
Probably a little mix of both!
These were fun to make, and made a tasty treat. I only had regular blue food color gel, so I didn’t reach that desired blue. I also preferred finer crumbles on top. Overall, a great recipe!
These cookies turned out very cute, but were tasteless! Some tweaking of the recipe needed for sure. Maybe use salted butter. Maybe the regular chocolate chip cookie recipe would be better and just turn it blue.
Hi Patricia! You can definitely use salted butter, just omit the additional salt that the recipe calls for.
