In a large mixing bowl, cream the butter and sugar until light and fluffy (around 3 minutes).
Add eggs one at a time and peppermint extract.
Mix the flour, cacao powder, baking powder and salt together in a bowl and gradually mix into the batter.
Mix in the chocolate chips.
Drop the dough on a greased baking sheet and bake for 8-10 minutes.
Let cookies cool before drizzling with chocolate and crushed candy cane.
Notes
If you plan to omit the chocolate drizzle and peppermint topping, you may want to add an additional ¼ teaspoon of peppermint extract to the dough.
The key in this recipe is creaming the butter and sugar until fluffy. It adds so much air and texture. I forgot to add baking powder in the batch of cookies I shot for this post, but you'd never know it! They still had a great fluffy texture thanks to taking a good 3 minutes to cream the butter and sugar - so definitely don't skip this step and make sure the butter truly is room temp (soft to the touch but not melted).
