Using a 1 tablespoon cookie scoop, portion the dough onto a small parchment lined baking sheet. Freeze for 15-30 minutes. Place the frozen cookie dough balls on the baking sheet about 2 inches apart. Top each of them with more chopped chocolate if desired. Bake for 8-10 minutes until barely golden on the edges.
Freeze, then bake
Once the cookies come out of the oven, immediately use a round cookie cutter or glass to scoot the edges in and make them perfectly round. Allow to cool completely on the baking sheet, and enjoy!
