Shaping & Baking:Using a standard cookie scoop, scoop 18 servings of the peanut butter cookie dough onto a sheet tray lined with parchment. Using the same scoop, scoop 18 servings of the chocolate dough on top of the peanut butter. Using your hands, roll the two doughs together into one ball.
Wrap sheet pan in plastic, and chill for at least 2 hours, overnight preferably.
Once ready to bake, preheat oven to 350ºF. Separate cookies onto 2 sheet trays, nine on each sheet - these cookies are quite large!
Bake 18-20 minutes, until the edges are beginning to brown. Rotate trays halfway if they are baking unevenly.
