What You'll Need
- Flour: Regular all-purpose gives these cookies their backbone.
- Cornstarch: This secret weapon makes them wonderfully soft.
- Butter: Make sure it's unsalted and soft for the best results.
- Sugars: Brown and white sugars team up for the perfect sweetness and chew.
- Eggs: Let them sit out until they reach room temp for better mixing.
- Gel Food Coloring: Mix royal blue, electric blue and violet to nail that monster blue color.
- Mix-ins: White chocolate chips, Chips Ahoy chunks, and Oreo pieces add amazing texture and flavor kicks.
Step By Step Directions
- Mix Your Base
- Beat the butter with both sugars until they're fluffy and pale. Mix in your eggs, vanilla, and blue coloring. Slowly add the dry stuff like flour, cornstarch, baking soda and salt until you've got thick, blue dough.
- Toss In The Goodies
- Gently stir in your white chocolate chips, Chips Ahoy pieces, and Oreo chunks by hand. This keeps everything from getting crushed while making sure every bite has something yummy.
- Form And Bake
- Roll dough into balls about 2 tablespoons big. Press extra chunks onto the outside to make them look more fun. Put them on a lined cookie sheet and bake at 350°F for 10-12 minutes. Pull them out before the edges turn brown to keep them soft.
- Let Them Rest
- Leave the cookies on the hot pan for about 15 minutes, then move them to a cooling rack. Dig in when you can't wait anymore!
Pro Secrets
Don't just scoop your flour, weigh it if you can to avoid dry cookies. Always go for gel food colors instead of liquid drops since they'll give you that deep monster blue. Bake just one tray at a time for the most even results. Want to go all out? Stick on some candy eyes or hide a chocolate chunk in the middle for a gooey surprise when you bite in.

Twists and Swaps
- Cookie Choices: Don't have Chips Ahoy? Try your own homemade cookies or grab some peanut butter ones instead.
- Chocolate Options: Throw in a combo of white, milk, or dark chocolate chips for more flavor depth.
- Fun Decorations: Stick on candy eyes to make them look like actual monsters.
- Hidden Surprises: Fold dough around pieces of chocolate bars for an amazing melty center.
Keeping Them Fresh
Pop your cooled treats in an airtight box and they'll stay good for 3 days on the counter or about 5 days in the fridge. The dough freezes great for up to 3 months - just let it thaw completely before you shape and bake. Or if you're in a hurry, you can bake them straight from frozen - just add a couple extra minutes to your timer.
