My easy Cookie Monster Cookies recipe is bursting with all the good stuff—milk chocolate chips, white chocolate chips, chopped chocolate chip cookies, and they even have a surprise Oreo stuffed inside! Inspired by the viral TikTok recipe, this version adds a few extra twists to make them even more fun and irresistible. I’ll walk you through how to get that bold blue Cookie Monster cookie dough just right, plus share some helpful tips and a printable recipe to make baking a breeze.
These soft Cookie Monster Cookies are basically blue chocolate chip cookies on cookie overload—in the best way possible. Unlike the original TikTok version that just had chocolate chips and a gooey chocolate bar center, we’re leveling things up with extra cookies mixed right in. They’re perfect for bake sales, parties, or when you just want a treat that makes everyone smile!

How to Make Blue Cookie Monster Cookies
If you want bold, vibrant blue cookies, gel food coloring is the way to go! Liquid food coloring just won’t cut it—no matter how much you use, it won’t give you that bright Cookie Monster blue.
For best results, you’ll need to use quite a bit of gel color. I used about half a tube to get that fun, eye-catching shade. You can also try food coloring paste, which is super concentrated and works just as well for vivid colors.
Natural blue food coloring, such as blue butterfly pea flower powder, can be used in this recipe. However, your cookies will likely not be as vibrant as if you used artificial gel food coloring.
➕ How to Make Cookie Monster Cookies
Measure the flour, sugars, chocolate chip cookies, and chocolate chips using a food scale. Chop the chocolate chip cookies into small pieces.
Mix the white flour, baking soda, and salt in a small bowl. Set it aside.
Put the butter, white sugar, brown sugar, and vanilla in a large mixing bowl. Use an electric hand mixer to beat it until creamy. Don’t overmix it- 1-2 minutes is plenty.
Beat the egg and food coloring into the sugar mixture. Add the flour mixture and mix again with the electric mixer. After the cookie dough in uniformly blue, stir in the chocolate chips and chocolate chip cookie pieces by hand.
Put the bowl with the cookie dough in the fridge and chill for one hour. Don’t skip this step! Room temperature cookie dough tends to overspread.
At the end of the chilling time, preheat the oven to 375F (190C). Line a large light-colored baking sheet with parchment paper.
Put tablespoon-sized balls of chilled dough on the cookie sheet. Use about half the dough (you should get 10-12 balls). Top each ball with an Oreo cookie, pressing the ball down to flatten.
Cover each cookie with an additional tablespoon of dough. Seal the dough around the edges so the Oreo cookie is completely hidden inside.
Bake the cookies for 9-10 minutes on an oven rack about halfway down from the top of the oven. The cookies should look a little underdone coming out of the oven.
Carefully press additional toppings into the cookies while they are still hot (if desired).
Let the cookies cool on the baking sheet for 10-15 minutes before moving them to a wire rack to finish cooling.
How to Know When Cookies are Done
Chocolate chip cookies can look a little underdone when they’re actually just right! You’re looking for bottoms that are lightly golden—not deeply browned. The tops may still look soft, and that’s okay.
It’s always better to slightly underbake; you can pop them back in the oven if needed. But once they’re overbaked, there’s no saving them!
Why do my cookies go hard?
If your cookies start out soft but turn hard after cooling, they were probably overbaked. Many cookie recipes (including this one!) should come out of the oven looking a little too soft. They’ll firm up as they cool—but stay nice and chewy if baked just right. 
How to Get Round Cookies
Want prettier cookies? You can gently nudge the edges into a rounder shape right after they come out of the oven. Just use a spoon or the edge of a spatula while the cookies are still soft and warm. Once they cool, they’ll set in place—so don’t wait too long!
That said, a little messiness is part of the charm. Cookie Monster cookies are meant to look a bit wild and fun—just like their namesake! 
How to Store Cookie Monster Cookies
Store your Cookie Monster cookies in a covered container in the fridge for up to 3–4 days. They’re best within the first day or two before they start to go stale.
Want to make them last longer? These cookies freeze beautifully! Just place them in an airtight container or freezer-safe bag, press out the air, and pop them in the freezer.
When you’re ready to enjoy, thaw them in the fridge or microwave individual cookies for 15-20 seconds. (You can eat them straight from the freezer, but they’re way better warmed up!)

Notes
💭 Expert Tips from Dietitian Summer Yule
This is a level 3 recipe (weight maintenance and active lifestyles). Let’s be real—cookies are usually loaded with white flour, added sugar, and added fat. While they’re not exactly a “health food,” there’s absolutely room for a cookie (or two!) in most balanced diets. That said, if you find yourself channeling Cookie Monster on a regular basis, it might be time to mix in a few more veggies and whole foods too. 😉 The great news? Cookie Monster Cookies freeze beautifully and make awesome gifts. If you don’t have a crowd at home to enjoy them, friends, neighbors, and coworkers will happily help you out. So go ahead and share the sweet rewards of your baking! Whether they’re little kids or just kids at heart, your fellow Cookie Monster fans will love the treat.
