These Easy Chewy Peanut Butter Oreo Cookies are filled with creamy peanut butter, crushed Oreo pieces, and chocolate chips. They bake up perfectly soft in the middle with slightly crisp edges and the perfect amount of chew.
Mix the melted butter and peanut butter. In the bowl of a stand mixer fitted with the paddle attachment, or a large bowl and a hand mixer, beat the melted butter and peanut butter until smooth.
Add the wet ingredients. Beat in the egg, vanilla extract, and vegetable oil, scraping the sides and the bottom of the bowl making sure everything is fully incorporated.
Add the dry ingredients. Add all of the flour mixture and mix until almost combined. Fold in the chocolate chips and crushed Oreo pieces. Cover bowl with plastic wrap and chill in the refrigerator for 45 minutes.
After 45 minutes, preheat the oven to 350 F. Using a cookie scoop, scoop dough to form 3 tablespoon sized dough balls using the palm of your hands. Using two fingers, gently flatten dough balls smoothing out any cracks.
Bake cookies at 350 F for 10 to 11 minutes. Top cookies with extra chocolate chips, Oreo pieces, and Oreo crumbs. Allow cookies to cool on baking sheet for 5 minutes then transfer to cooling rack to cool completely.
