Preheat Oven at 350°F (175°C) and line a baking sheet with parchment paper.
Crush the Oreos into small chunks (not fine crumbs) so you get soft bites with Oreo texture.
Cream Butter, brown sugar, and granulated sugar together until smooth and fluffy (about 2 minutes).
Mix in the egg and vanilla extract until well combined
In a separate bowl, whisk together flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients and mix until just combined.
Fold in Oreos until evenly distributed.
Roll dough into 1.5-inch balls, placing them 2 inches apart on the baking sheet. Bake for 8-10 minutes for soft and chewy cookies (until edges are set but centers remain soft) or 12-15 minutes for crunchy cookies (until it’s golden brown on top)
Let cookies rest on the baking sheet for 5 minutes before transferring to a wire rack.
Enjoy with a cup of milk or coffee
