Must-Have Components
- Flour: Regular all-purpose gives these cookies their backbone.
- Cornstarch: This secret weapon makes them extra soft.
- Butter: Go with the unsalted, softened kind for that rich taste.
- Sugars: Both brown and white work together for sweetness and chew.
- Eggs: Make sure they're not cold from the fridge.
- Gel Food Coloring: Mix royal blue, electric blue and violet to nail that monster look.
- Add-ins: White chocolate chips, chopped up Chips Ahoy, and broken Oreos create amazing flavor layers.
Step-By-Step Guide
- Mix Your Base
- Beat the butter with both sugars until it's fluffy and pale. Drop in eggs, vanilla, and your blue gel colors. Slowly add your dry mix (flour, cornstarch, baking soda, salt) until you've got thick dough.
- Toss In The Goodies
- Use your hands to fold white chocolate chips, Chips Ahoy pieces, and Oreo chunks through the dough. Manual mixing works best for even distribution.
- Get Them Ready For The Oven
- Roll 2-tablespoon chunks of dough into balls. Press extra cookie bits on the outside for a fun look. Space them on your lined cookie sheet and bake at 350°F (175°C) for about 10-12 minutes. Take them out before the edges turn brown.
- Let Them Rest
- Keep cookies on the hot sheet for 15 minutes, then move them to a rack. Dig in once they've cooled a bit!
Pro Secrets
Don't guess with your flour—measure it right or your cookies might end up too dry. Always pick gel food coloring instead of the liquid stuff for that deep blue color you want. Bake just one tray at a time for the best results. Want to go all out? Stick on some candy eyes, or hide a chunk of chocolate inside each cookie for a surprise when you bite in.

Switch It Up
- Different Cookies: Try your own homemade cookies instead of Chips Ahoy or go for peanut butter ones.
- Chip Choices: Mix up white, milk and dark chocolate chips for more flavor fun.
- Googly Eyes: Pop on some candy eyeballs to make them look like real monsters.
- Hidden Surprise: Tuck a piece of chocolate bar inside each cookie for a melty middle.
Keep 'Em Fresh
Put leftover cookies in an airtight box and they'll stay good for 3 days on your counter or 5 days in your fridge. You can also freeze the raw dough for up to 3 months—just let it thaw before you shape it. In a hurry? Bake them straight from frozen, just add a few more minutes to your timer.
