These Blue Cookie Monster Cookies are a vibrant and fun twist on classic chocolate chip cookies, featuring three shades of blue dough marbled together with white chocolate chips and chunks of mini Chips Ahoy and Oreo cookies for extra crunch and flavor.

Ingredients

Dry Ingredients

  • 3 cups (360g) all-purpose flour
  • 2 teaspoons cornstarch
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt

Wet Ingredients

  • 2 sticks (1 cup) unsalted butter, softened to room temperature
  • 1 1/4 cups packed light brown sugar
  • 1/4 cup granulated sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon pure vanilla extract

Coloring and Mix-ins

  • Royal blue gel food coloring
  • Electric blue gel food coloring
  • Violet gel food coloring
  • 2/3 cup white chocolate chips, divided
  • 2/3 cup chopped mini Chips Ahoy cookies
  • 2/3 cup chopped Oreo cookies

Instructions

  1. Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt until well combined. Set this mixture aside for later use.
  2. Cream butter and sugars: In a large bowl, using a mixer, cream together the softened unsalted butter with the packed light brown sugar and granulated sugar until the texture is light and fluffy. This will take about 3-5 minutes on medium speed.
  3. Add eggs and vanilla: Beat in the eggs one at a time to the creamed mixture, making sure each is fully incorporated before adding the next. Stir in the pure vanilla extract to combine.
  4. Divide and color dough: Separate the wet dough mixture evenly into three portions. Tint each portion with royal blue, electric blue, and violet gel food coloring respectively, stirring until the color is evenly distributed and vibrant.
  5. Combine dry and colored wet ingredients: Gradually add the dry ingredient mixture to each colored dough portion. Mix on low speed or fold gently until just combined to avoid overworking the dough and toughening the cookies.
  6. Add mix-ins: To each colored dough portion, add about half of the white chocolate chips. Divide the chopped mini Chips Ahoy cookies between the royal and electric blue dough portions, and divide the chopped Oreo cookies between the royal and violet blue dough portions. Gently fold in the mix-ins until evenly distributed.
  7. Shape the cookies: Scoop spoonfuls of each colored dough and gently press them together to create marbled dough balls. Roll into balls and place them on baking sheets lined with parchment paper. Vary the amount of each color used for unique, colorful effects in each cookie.
  8. Bake: Preheat the oven to 375°F (190°C). Bake the cookie balls for 11 minutes or until the edges are lightly golden but the centers remain soft. This ensures chewy, tender cookies.
  9. Cool: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This helps them set properly without breaking apart.

Notes

  • Use gel food coloring to achieve vibrant, evenly-colored dough without altering dough consistency.
  • Do not overmix the dough once dry ingredients are added to keep cookies tender.
  • Chilling the dough for 30 minutes before baking can improve texture and prevent spreading, though it's optional.
  • If mini Chips Ahoy or Oreos are unavailable, substitute with your favorite crunchy chocolate cookies.
  • For softer centers, remove cookies from the oven as soon as edges turn golden, and allow residual heat to finish baking.
