Oreo Cookies

Cream together unsalted butter and powdered sugar until smooth texture. Beat in egg. In a separate bowl, whisk together the flour, baking soda, and a pinch of salt. Gradually add the flour mixture to the butter mixture and mix until just combined. Fold in the crushed oreo. Take small portions of the dough and flatten them into circles (each weighs about 30g). Place the cookies on a baking sheet lined with parchment paper, and place some more chocolate chips on top of each dough for decoration. Bake the cookies in a preheated oven at 350F (190°C) for 15 minutes or until the edges are golden brown.
