Ingredients
Method
- Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.

- Add blue food coloring a little at a time until the desired Cookie Monster blue color is achieved.
- Fold in the chocolate chips and crushed sandwich cookies if using.
- Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Bake for 9 to 11 minutes, or until the edges are set and the centers still look slightly soft.
- Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
- If desired, decorate with candy eyes and additional chocolate chips while the cookies are still slightly warm.
- Cool completely before serving or storing.
Notes
- Do not overbake. The cookies will continue to set as they cool.

- White cake mix works best for achieving the bright blue color, but vanilla cake mix can also be used.
How to Make Cookie Monster Cake Mix Cookies
Step 1: Prepare the Oven and Baking Sheets
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking and make cleanup easier.
Step 2: Mix the Cookie Dough
In a large mixing bowl, combine the cake mix, eggs, and vegetable oil until a thick dough forms. Add blue food coloring and mix until the color is evenly distributed throughout the dough.
Step 3: Fold in the Mix-Ins
Gently stir in the chocolate chips and any crushed chocolate sandwich cookies if using. Mix just until everything is evenly incorporated.
Step 4: Scoop the Cookies
Using a cookie scoop or tablespoon, portion the dough into evenly sized balls and place them on the prepared baking sheets, leaving about 2 inches of space between each cookie.
Step 5: Bake Until Set
Bake for 9–11 minutes, or until the edges are lightly set while the centers still look slightly soft. Avoid overbaking to keep the cookies chewy.
Step 6: Cool on the Baking Sheet
Allow the cookies to cool on the baking sheet for 5 minutes. They will continue to set as they cool.
Step 7: Transfer and Decorate
Move the cookies to a wire rack to cool completely. If desired, press extra chocolate chips, cookie pieces, or candy eyes into the tops for a fun Cookie Monster-inspired look.
Step 8: Serve and Enjoy
Serve immediately or store in an airtight container for up to 4 days. Enjoy these colorful, chewy cookies with a cold glass of milk.
