Preheat oven to 350 F and line two cookie sheets with parchment paper or foil.
In a large bowl, beat butter, granulated sugar, brown sugar, and vanilla extract in a large mixer bowl until creamy.
Add eggs, one at a time, beating well after each addition. Add blue food coloring if desired.
Gradually add flour a little at a time until just combined. Do not over-mix.
Fold in chocolate chips, 1 1⁄2 cups chopped chip ahoy cookies, and 1 1⁄2 cups chopped Oreos.
Sprinkle with remaining chopped cookies.
Bake for 9-11 minutes. Cool on baking sheet for 2 minutes. Cool on wire racks completely.
Notes
Ingredient Notes and Shopping Tips
Butter: Allow butter to soften at room temperature for 30-60 minutes. If you're short on time try cubing it up into smaller pieces. Avoid the microwave as melted butter can make cookies spread.
Eggs: Bring eggs to room temperature for ~30 minutes to help them mix in smoothly.
Flour: Measure flour by spooning it into a measuring cup. Dipping your cup in the flour will result in too much.
Baking Soda: Replace it every 6-12 months as it can lose its potency.
Oreos: I used Double Stuf, because why not?!
Chips Ahoy: Make sure you use a crunchy variety so they'll hold their own in the dough.
Food Coloring: I opted for gel food coloring which is more concentrated leading to a brighter color.
Tips and Tricks
Don't Overmix: Mix until the flour just disappears. Overmixing will lead to a tough cookie.
Don't Overbake: Bake until the edges are set. Overbaking leads to a dry cookie.
Cool on the Pan: If you try to remove them right away they'll fall apart.
Cool Your Pan: Cool the pan for around 5 minutes before refilling it with cookie dough.
If your dough is sticky and hard to work with try chilling it for 30-60 minutes.
