Blue Cookie Monster Cookies with Oreos & Chips Ahoy (Print version)

Chewy bright blue cookies loaded with chopped Oreos, Chips Ahoy, and two kinds of chocolate chips.

# Ingredients:

For the dry mix

01 - 2 1/3 cups (280 g) all-purpose flour
02 - 1 teaspoon baking soda
03 - 1 1/2 teaspoons cornstarch
04 - 1/2 teaspoon fine sea salt

For the dough

05 - 3/4 cup (170 g) unsalted butter, melted and cooled
06 - 1/2 cup (100 g) granulated sugar
07 - 3/4 cup packed (150 g) light brown sugar
08 - 1 large egg
09 - 1 large egg yolk
10 - 2 teaspoons vanilla extract
11 - 5-7 drops blue gel food coloring, plus a tiny drop of purple gel if needed

For the mix-ins

12 - 1/3 cup (60 g) white chocolate chips
13 - 1/3 cup (60 g) milk chocolate chips
14 - 1/2 cup (50 g) chopped Oreos
15 - 1/2 cup (50 g) chopped Chips Ahoy cookies

# Instructions:

01 - In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt until evenly combined.
02 - In a large bowl, stir the melted cooled butter with the granulated sugar and brown sugar until glossy and mostly smooth.
03 - Stir in the egg, egg yolk, vanilla, and blue gel food coloring until the mixture is smooth and evenly blue. Add a tiny dot of purple gel only if the color looks greenish.
04 - Add the dry ingredients to the wet ingredients and stir just until no flour streaks remain. Fold in the white chocolate chips, milk chocolate chips, chopped Oreos, and chopped Chips Ahoy cookies.
05 - Cover the dough and chill for at least 2 hours. Preheat the oven to 325 F and line baking sheets with parchment. Scoop large 3-tablespoon dough balls, spacing them 3 inches apart.
06 - Bake for 13-15 minutes, until the cookies are puffed and the edges are set. The centers should still look a little soft.
07 - Let the cookies cool on the baking sheet for 10 minutes, then move them to a wire rack to cool completely.

# Good to know:

01 - Chill time is at least 2 hours and is not included in the active prep time.
02 - For brighter tops, press extra cookie chunks and chocolate chips onto the dough balls before baking.
03 - Nutrition is an estimate per large cookie.
