Cookie Monster Cookies are the ultimate treat for anyone who loves thick bakery-style cookies packed with chocolate and a little nostalgia. This version borrows the TikTok favorite and takes it even further with layers of crispy cookie chunks and gooey chocolate hidden inside.
I made these after my kids saw them online and now they beg for “blue cookies” for every birthday and sleepover because they say they taste even better than the ones on TikTok.
Ingredients
- Butter: room temp for creamy soft dough use good quality for flavor
- Light brown sugar: adds caramel notes and chew make sure it is packed into the cup
- Granulated sugar: gives structure and balances sweetness
- Eggs: bind the dough for rich texture use large and fresh
- Vanilla: for classic cookie aroma and warmth pure vanilla makes a difference
- Blue food coloring: for signature Cookie Monster look gel color works best for vibrant blue
- Salt: enhances all the other flavors use fine salt for even mixing
- Baking powder: helps make cookies thick and soft
- Flour: all purpose holds everything together use the spoon and level method to measure
- Semisweet chocolate chips: Main chocolate flavor use your favorite brand
- White chocolate chips: add sweetness and color contrast high quality chips melt best
- Chopped Oreos: classic cookies and cream element choose regular rather than double stuff
- Chopped crispy chocolate chip cookies: for texture and crunch try to use Famous Amos or another crunchy mini cookie
- Milk chocolate discs or large chunks: for gooey melty pockets in the middle
- Extra chocolate chips, chopped Oreos, and crispy cookies: for topping make the cookies bakery worthy
Step-by-Step Instructions
- Cream the Butter and Sugars:
- Beat butter with light brown and white sugar for one full minute until totally smooth and beginning to lighten in color. This base creates the signature chewy texture.
- Aerate with Eggs and Vanilla:
- Add eggs and vanilla extract then continue beating for three full minutes. The mixture will get extra fluffy and light. Be generous with the time and scrape down the sides to make sure all the butter mixes in evenly.
- Tint the Dough:
- Add drops of blue food coloring a bit at a time until you reach your favorite Cookie Monster shade. Gel coloring works fastest for a deep blue. Mix just until evenly tinted.
- Add Dry Ingredients:
- Sprinkle in salt and baking powder then add flour gradually. Mix just until all the flour disappears and you have a smooth dough. Over mixing at this stage can make cookies tough.
- Mix in the Goodies:
- Fold in semisweet chocolate chips white chocolate chips chopped Oreos and crushed crispy chocolate chip cookies. Every part of the dough should have some mix-ins for true Cookie Monster cookies.
- Chill if Needed:
- If the dough feels especially soft or the kitchen is warm pop the bowl in the fridge for about 30 minutes so cookies hold their shape and do not spread too much when baking.
- Add Melty Chocolate Centers:
- Scoop up two tablespoons of dough and flatten it in your hand. Lay two or three milk chocolate discs in the center then wrap the dough up and seal the chocolate inside. Top with another two tablespoons of dough to fully cover.
- Make The Cookies Extra Special:
- Top each dough ball with a few pieces of each mix-in. Push chocolate chips Oreo pieces and crispy cookies onto the top so they look just as fun and inviting as they taste.
- Bake to Perfection:
- Set cookies on a lined baking sheet spaced apart as they will spread. Bake at 350 degrees Fahrenheit for about 10 to 12 minutes until edges are golden and centers look just barely done. The insides will stay gooey as they cool.
- Let Them Cool and Enjoy:
- After baking let the cookies cool on the sheet for five minutes to help them firm up before transferring to a rack. The cookies are amazing eaten warm.

The way the crispy cookie bits add crunch to every bite is what hooked me I still remember the look on my daughter’s face when she first broke into a blue cookie and found the melty chocolate inside She called them magic cookies and I have to agree
Storage Tips
Keep baked cookies in an airtight container at room temperature for up to five days. For longer storage freeze the cookies in a freezer safe bag between layers of parchment. Thaw at room temperature or rewarm in a low oven to bring back that gooey center.
Ingredient Substitutions
You can swap in dark or milk chocolate chips if you prefer a sweeter or milder cookie. For the crispy cookie chunks try graham crackers or another crunchy cookie if you cannot find Famous Amos. Food coloring is optional but key for that signature look.

Serving Suggestions
Serve the cookies warm for a classic bakery style treat or with ice cream sandwiched in between for a homemade cookie monster ice cream sandwich. They look great on party platters and kids will love helping add the toppings.
Origin and Fun Facts
These cookies got their start on TikTok as a fun over the top treat but the flavor mix of chocolate and Oreos is just as nostalgic for adults. Each cookie is a playful nod to the classic Cookie Monster and adds instant fun to any celebration or bake sale.
