Cream Cheese Peanut Butter Cookies are soft, chewy and packed with peanut butter! Made with Reese's pieces, these peanut butter cookies turn out perfectly every time.
Add the butter and cream cheese to a large bowl and beat for 2-3 minutes with an electric mixer. Add the egg, vanilla and peanut butter and mix for another 2-3 minutes. Add the sugars and mix for 2-3 more minutes.
Add the flour, baking soda, baking powder, salt and cornstarch. Mix just until combined. With a wooden spoon or spatula, fold in the chocolate chips and Reese's pieces.
Use a cookie scoop to scoop dough onto cookie sheets that are lined with parchment paper or silicone baking mats. At this point, I usually gently press a few more Reese's pieces on the top of the cookie dough so that the cookies look prettier when they are cooked.
Bake for 12 minutes or until the edges just barely begin to brown. Let the cookies cool on the baking sheet for about 3-5 minutes before transferring to a wire rack to cool completely.
