Blue Monster Treats are eye-catching, vivid blue goodies that take after everyone's favorite cookie-loving character from Sesame Street. They're loaded with chunks of white chocolate, bits of Chips Ahoy, and smashed Oreos throughout. The cookies come out soft in the middle with a slight chew, winning over kids and grown-ups too. They work great for birthday bashes, classroom events, or when you just want something fun to munch on that'll bring out your inner cookie fanatic.

What Makes These Special

You'll fall for these treats because they're playful, tasty, and super simple to whip up. Their bright blue color and mix of cookie chunks and chocolate make them perfect when you need something impressive but don't want to spend hours in the kitchen. Little ones go crazy for the monster theme, while the blend of tender dough, gooey middle, and crunchy add-ins keeps everyone coming back for seconds.

Must-Have Components

  • Flour: Regular all-purpose flour builds the cookie base.
  • Cornstarch: This secret ingredient makes your cookies extra tender.
  • Butter: Make sure it's soft and unsalted for the best flavor.
  • Sugars: We use both brown and white to get that perfect sweet chew.
  • Eggs: Let them sit out before using so they blend better.
  • Gel Food Coloring: Mix royal blue, electric blue, and violet for that iconic monster shade.
  • Add-ins: White chocolate bits, chopped store-bought cookies, and broken Oreos give amazing texture.

How To Make Blue Monster Treats

Mix Your Cookie Base
Beat together your soft butter with both sugars until it looks fluffy and light. Then add in eggs, vanilla, and your blue coloring. Slowly mix your dry stuff (flour, cornstarch, baking soda, salt) until you get a nice thick dough.
Toss In The Goodies
Use your hands or a spoon to fold in white chocolate chips, broken Chips Ahoy pieces, and Oreo chunks. Don't overmix—just enough to spread everything around.
Get Them Ready For The Oven
Roll dough into balls about 2 tablespoons big. Press extra cookie bits on top to make them look fun. Put them on a lined cookie sheet and bake at 350°F for 10-12 minutes. Take them out before they brown so they stay soft.
Let Them Rest
The cookies need to sit on the hot pan for about 15 minutes before you move them to a cooling rack. Then dig in!

Pro Advice

Don't just scoop flour—weigh it or spoon it carefully into measuring cups to keep your cookies from turning out too dry. Always go with gel food colors instead of the liquid kind if you want that deep blue color. Bake just one tray at a time for cookies that cook evenly. Want to make them extra cute? Stick on some candy eyes, or try putting a chunk of chocolate in the middle of each dough ball for a melty surprise when you bite in.

Mix It Up

  • Switch The Cookies: Try using homemade chocolate chip cookies or grab peanut butter ones instead of Chips Ahoy.
  • Play With Chocolate: Throw in a combo of white, milk, and dark chips for more flavor fun.
  • Add Some Face: Stick on candy eyeballs to really nail that monster look.
  • Hidden Surprise: Tuck a piece of chocolate bar inside each cookie for an amazing gooey center.

Keep 'Em Fresh

Your cookies will stay good in a sealed container on the counter for about 3 days, or up to 5 days in the fridge. The raw dough freezes well for up to 3 months—just let it thaw completely before you shape it. Or if you're in a hurry, you can bake them straight from frozen—just add a few more minutes to your baking time.
