In the bowl of a stand mixer (or in large bowl using electrical mixer), cream together butter and sugars until light and fluffy. Scrape sides of bowl.

Add eggs and vanilla extract. Beat until well-combined.

In a separate bowl, whisk together flour, cornstarch, baking soda, baking powder, and salt.

Gradually add dry ingredients to wet, stirring until well-combined.

Fold in 1 cup of chocolate chips, reserve remaining ½ for later.

Place 5 Oreo cookies in a small plastic bag and use a rolling pin or mallet to break into small pieces.  Use a spatula to fold cookie bits into dough.

Cover dough and chill in refrigerator for 15-30 minutes.

Scoop 1 ½ Tbsp of dough, flatten between your palms, and place on top of one Oreo cookie.  Wrap another 1 ½ Tbsp of dough around the bottom of the cookie and mold the dough around the cookie until it's completely covered (add more dough, if needed).  Repeat with remaining Oreo cookies.

Place dough on a wax paper lined plate and freeze for 20-30 minutes.  Meanwhile, preheat oven to 375F (190C).

Once dough has chilled and oven is preheated, place dough on parchment paper lined cookie sheet, spacing each cookie at least 2" apart, and bake on 375 for 11 minutes,

Within 2 minutes of removing cookies from oven, gently nestle remaining chocolate chips on top of each cookie.

Allow to cool before enjoying.
