Peanut Butter Chocolate Chip Cookies

Preheat oven to 350ºF and line a baking sheet with parchment paper or a nonstick baking mat.

In a medium bowl mix together flour, cornstarch, baking soda, and salt; set aside.

In a stand mixer fitted with a paddle attachment, cream together butter and peanut butter until thoroughly incorporated and fluffy. Mix in egg, vanilla and milk, scraping down sides as necessary. Next add both sugars. Finally, mix in the flour mixture. Stir in chocolate chips.

Measure 2 tablespoons of dough and place on baking sheet. Bake 13-15 minutes (mine took 14 minutes). Let cool on a cooling rack.
