Step 1

Preheat the oven to 375F and line a baking sheet with parchement paper then set aside.

Step 2

In a large mixing bowl or a stand mixer bowl, cream the cold butter, cold shortening, granulated sugar and brown sugar together until light and creamy.

Step 3

Add in the eggs and the vnailla extract and mix until combined.

Step 4

Sift in the flour, corn starch, baking soda, and salt and mix just until the flour mixture disappears. Add in the milk chocolate chips and gently fold.

Step 5

Using a 1/4 cup measuring cup, scoop out 12 evenly sized cookie dough balls. Working with one at a time, split each cookie dough ball in half and smoch back together keeping the jagged edge side up. Chill the cookie dough balls in the freezer for 15 minutes then bake in the preheated oven for 13-15 minutes or until they look slightly golden brown and undercooked.

Step 6

As soon as you pull out the cookies from the oven, using a larger cookie cutter swoosh around your cookies to form the perfect round thick cookie, top with a few extra chocolate chips and let the cookie rest on the baking sheet for 20 minutes to set fully before enjoying them.
