Preheat oven to 350 degrees Fahrenheit. Line cookie sheet trays with parchment paper or a silicone mat.

Using an electric hand or stand mixer with the paddle attachment, cream the butter and sugars together until light and fluffy. Add the eggs and vanilla. Mix well and scrape bowl.

Combine the flour, baking soda, and salt in a separate bowl. Add the dry ingredients to the wet ingredients. Mix until just combined.

Chop up the Hershey’s Cookies ‘n’ Creme Bars and Oreo cookies. Fold chopped pieces into cookie dough. (You can save a few pieces of candy bar or Oreos to press into the top if you want.)

Shape into cookie dough balls (about 2 Tbsp each; or with a #30 scoop) and place on prepared trays. NOTE: Dough may seem a tad dry and crumbly. Use hands to slightly warm and round dough better. (Press any extra pieces of candy bar or Oreos on top, if desired.)

Bake at 350˚F for 11-12 minutes or until the edges are just barely starting to brown. Allow cookies to rest for 1-2 minutes on the tray, then transfer them to a wire rack to cool completely. TIP: May round misshapen cookies with spatula immediately after baking.
