Line a baking sheet with parchment paper. Use a medium sized cookie dough scoop, about 2-2.5 tablespoons of dough per ball, to scoop 20 even cookies and place on the prepared baking sheet. Refrigerate for 30 minutes to chill the cookie dough. This will help to enhance the flavor and prevent spreading.

Preheat the oven to 350°F. If you leave the dough in the fridge longer than 45 minutes, allow it to sit on the counter for 5 minutes before baking. Once the cookie dough has chilled, space each ball about 2 inches apart on a cookie sheet lined with parchment paper and bake for 9-10 minutes, or until the edges are just set.

While the cookies are cooling, make the ganache. Break the chocolate into pieces (unless using chocolate chips) and place in a heatproof bowl. Heat the cream in a small pot on the stove over medium heat until it starts to simmer. Pour over the chocolate and let it sit for 5 minutes. After 5 minutes, add in the vanilla extract and peppermint extract (if using) and use a whisk to stir until completely smooth. Let cool for 15-30 minutes, or until it is a spreadable consistency.
