Step 1

In the bowl of a stand mixer or in a large bowl if using an electric hand mixer, cream together butter, cream cheese, and sugars for 2-3 minutes.

Step 2

Add egg, egg yolk, and vanilla extract, beat until well-combined, stopping once to scrape the bottom and sides of the bowl.

Step 3

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

Step 4

With the mixer on low speed, slowly add the flour mixture to the butter mixture. Make sure to stop to scrape the bottom and sides of the bowl.

Step 5

Add broken Oreos and mini chocolate chips and use a spatula to stir them in until incorporated.

Step 6

Cover the bowl with plastic wrap and refrigerate for 30 minutes.

Step 7

Preheat oven to 350 degrees F. Prepare two cookie sheets by covering them with parchment paper.

Step 8

Remove cookie dough from the fridge and drop 1 ½ tablespoon-sized scoops of cookie dough onto the baking sheets, spacing cookies at least 2 inches apart.

Step 9

Bake for 10-12 minutes or until cookies just begin to turn golden brown around the edges.

Step 10

Right after you remove them from the oven, press a few additional chocolate chips into all the cookies. They will look nicer.

Step 11

Allow cookies to cool completely on the baking sheet before serving.
