Start by creaming together the butter and sugar. Proper creaming should take approximately 5 minutes.
Once the butter and sugar are creamed and fluffy, add in eggs one at a time and mix.
Pour in melted chocolate and peppermint, then whisk to incorporate.
Slowly pour in flour and baking soda and fold in the chocolate chips.
Scoop the batter using a large cookie scoop and place onto a baking sheet. Cover with plastic wrap for 1 hour or overnight.
30 minutes prior to baking, preheat the oven to 350º.
Line another baking sheet and place 8-9 cookie balls on the sheet and bake 350° 11-12 minutes.
Let cool for 30m before serving.
Notes
This recipe is meant to be chilled before baking. I have tried with an overnight chill, and also with a 1-hour chill. They both yield super soft and chewy results.Adding the perfect amount of peppermint extract is crucial, because any more than the recommended amount will take the chocolate and mint flavor out of balance. Also, don't use peppermint essential oil, that's not the same as extract!Before chilling the batter, scoop the dough into the cookie balls beforehand. Way easier to grab and bake than scooping chilled dough. Plus, any leftover you can throw in a ziplock bag and freeze.The cookies will continue to bake and set after they are taken out of the oven, so be sure to time them efficiently so that they don't over bake! The outer edge of the cookie should feel firm, but the inside should have a little bounce to it.
