Over a medium sized sauce pan, in lowest heat, melt chocolate and butter, stirring occasionally. In a separate bowl, mix flour, cocoa, baking powder and salt
Over a mixing bowl with a whisk attachment combine eggs, granulated sugar, light brown sugar and peppermint extract, and whisk on high speed for 4-5 minutes, until light and fluffy
Reduce speed and beat in chocolate mixture for 1 minute. Add flour mixture and mix until combined. Do not over beat!. Fold in chocolate chips, cover and refrigerate for 1 hour
Pre-heat oven to 350 F and line 3 baking sheets with parchment paper. Using a 1.5 Tablespoon cookie scoop, form cookies and place them on prepared parchment paper 2.5 inches apart. Dough will be very sticky!
Bake for 10 minutes, remove from the oven and if cookies are irregular, use a circular cookie cutter slightly bigger than your cookies and make a circular motion to swirl the cookies around inside the cookie cutter.
This needs to be done when cookies are still warm! let cool for 3 minutes, then transfer to a wire rack to cool completely. Using a piping bag, drizzle cookies with white chocolate and sprinkle with peppermint candy.
