Step 1

Preheat your oven to 375 degrees. Line 2 cookie sheets with parchment paper.

Step 2

In a medium bowl whisk together; 2 and 1/4 cups of flour, 1/2 teaspoon of salt, 1 teaspoon of baking soda, 1 and 1/2 teaspoons of corn starch. Set aside.

Step 3

In your stand mixer bowl, or in a separate bowl, mix 1 and 1/2 sticks of melted butter, 3/4 cup of brown sugar, 1/2 cup of granulated sugar, 2 teaspoons of vanilla, 1 egg, plus an extra egg yolk.

Step 4

Once combined stir the dry ingredients into the wet a little at a time in your stand mixer using the paddle attachment or with a hand mixer, until just combined.

Step 5

In a small zip lock bag, seal in 15 Oreo cookies. Use a rolling pin, hammer, whatever you have on hand to crush into medium sized oreo crumbles. You do not want dust, chunks are good! On a cutting board, chop half of your Hershey's cookie and creme bar into small pieces. Pour the Oreo crumbles, Hershey's bar pieces, and 1/2 cup of Ghirardelli white chocolate chips into the dough. Mix until combined on stand mixer or by hand. I find the stand mixer is easier!

Step 6

Use a large ice-cream scoop to scoop 6 large heaping dough balls. DO NOT roll around or squeeze to make a firm dough ball. A loose packed ball is what you are looking for. Refer to picture.

Step 7

Place 3 dough balls per cookie sheet. Bake 12 minutes exact. When you take them hot out of the oven, top with Oreo crumbles and 1 Hershey square. ENJOY (:
