How to Make Cookie Monster Cookies
- Preheat your oven to 375°F and line two baking sheets with parchment paper.
- In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
- In a large bowl, beat softened butter, granulated sugar, and brown sugar until creamy and fluffy, about 2-3 minutes.
- Add the egg and vanilla extract to the butter mixture, beating well to combine.
- Slowly mix in the dry ingredients until just combined, then fold in both types of chocolate chips evenly.
- Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Bake cookies for 10-12 minutes or until edges are golden but centers still look soft. Let them cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
- While cookies cool, prepare the frosting by beating the softened butter with powdered sugar, milk, vanilla extract, and blue gel food coloring until smooth and fluffy. Add milk a little at a time if needed to reach spreading consistency.
- Once cookies are completely cool, generously spread blue frosting on each cookie to create the classic cookie monster look.
Tips for the Best Results
- Use room temperature butter for easier creaming and a lighter cookie texture.
- Don’t overmix the dough to keep cookies tender and chewy.
- Allow cookies to cool fully before frosting to prevent melting or sliding.
- Adjust the amount of blue food coloring to achieve your preferred shade.
- For extra fun, add googly candy eyes or sprinkles on top of the frosting.
Storage and Reheating
Store your cookie monster cookies in an airtight container at room temperature for up to 4 days to keep them soft and fresh. If you want to extend their shelf life, you can refrigerate them for up to a week, but bring them back to room temperature before enjoying for the best flavor.
For longer storage, freeze the cookies without frosting in a sealed container or freezer bag for up to 3 months. Thaw completely and then add frosting before serving. To warm cookies slightly, microwave for 10-15 seconds, but avoid overheating to preserve frosting texture.
Frequently Asked Questions

How do I make the frosting less sweet?
To reduce sweetness, cut back on powdered sugar slightly and add a splash more milk to keep the frosting spreadable and smooth without losing flavor.
Can I make these cookies gluten-free?
Yes, substitute all-purpose flour with a gluten-free flour blend designed for baking, and ensure your baking soda and other ingredients are gluten-free certified for best results.
What’s the best way to decorate for a cookie monster look?
Use blue frosting as the base, then add candy eyes or white chocolate chips for eyes and mini chocolate chips for the mouth to create a fun cookie monster face.
