These irresistibly blue cookies combine the perfect harmony of white chocolate chips, Chips Ahoy pieces, and chopped Oreos. Every bite brings you a soft, chewy texture punctuated with delightful crunchy surprises that make these monster cookies absolutely unforgettable.
Last weekend, I made these with my nieces and the joy on their faces watching the dough turn blue was priceless. The kitchen was filled with giggles and sneaky cookie dough sampling, making it a memory we'll cherish forever.
Essential Cookie Components
- All-purpose flour: Creates the perfect foundation for our chewy cookie texture - look for unbleached variety for the best results
- Cornstarch: Our secret weapon for that melt-in-your-mouth tenderness - don't skip this ingredient
- Room temperature butter: Essential for the perfect creamy base - leave it out for at least 2 hours before baking
- Brown sugar: Brings moisture and a subtle caramel note - dark or light both work beautifully
- Gel food coloring trio: The key to achieving that perfect monster blue shade without affecting the texture

Creating Cookie Magic
- Beginning Steps
- Mix your dry ingredients with care, ensuring even distribution of the cornstarch and baking soda. This creates the perfect foundation for our monster cookies.
- Color Creation
- Combine the butter and sugars until they transform into a light, fluffy cloud. This step is crucial for achieving our perfect cookie texture.
- Dough Formation
- Gradually incorporate your dry ingredients while adding the magical blue color combination. Watch as your dough transforms into a beautiful blue masterpiece.
- Cookie Assembly
- Shape your dough into perfect spheres, studding them with extra goodies. This is where your cookies get their signature monster appearance.
- Baking Brilliance
- Transform your cookie dough into perfectly baked treats, watching carefully for that ideal moment to pull them from the oven.
My family particularly loves the white chocolate chips in these cookies. Something about how they melt slightly into the warm cookie creates pockets of creamy sweetness that's simply irresistible.
Perfect Pairings
Serve these vibrant treats alongside a cold glass of milk for the classic combination. For special occasions, try them with vanilla bean ice cream for an elevated dessert experience.
Creative Twists
Transform these cookies by using different cookie pieces like golden Oreos or adding coconut flakes. For a nutty variation, try adding chopped macadamia nuts.
Keeping Your Cookies Fresh
Store these beauties in an airtight container at room temperature for up to five days. Layer them between parchment paper to maintain their perfect appearance.

Chef's Wisdom
- Allow your ingredients to reach room temperature for the best texture

Making these cookies has become a monthly tradition in my kitchen. There's something magical about watching simple ingredients transform into these vibrant, delicious treats that never fails to bring smiles to everyone's faces.
