Preheat your oven: Set your oven to 350°F (180°C). Line two baking sheets with parchment paper.
Combine dry ingredients: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
Cream butter and sugars: In a large mixing bowl, beat the butter, brown sugar, and granulated sugar together until light and fluffy.
Add eggs and vanilla: Mix in the eggs one at a time, followed by the vanilla extract.
Incorporate dry ingredients: Gradually add the dry mixture to the wet ingredients and mix until just combined.
Fold in Oreos and chocolate chips: Gently fold in the crushed Oreos and chocolate chips until evenly distributed throughout the dough.
Shape the dough: Scoop about 2 tablespoons of dough per cookie and place onto the prepared baking sheets. Leave space between each cookie.
Decorate: Press a few extra Oreo chunks and chocolate chips on top of each dough ball for a more festive look.
Bake: Bake for 10–13 minutes, or until the edges are lightly golden but the centers still look slightly soft.
Cool: Let the cookies rest on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
