In a medium size bowl, whisk together the gluten free flour, cocoa powder, baking soda, baking powder, salt, and protein powder. Set aside.
In a separate bowl, add the butter, brown sugar, and granulated sugar and mix until completely combined.
Mix in the eggs one at a time. Then add in the peppermint extract and vanilla extract. Scrape down the sides of the bowl with a spatula.
Add the dry ingredients to wet ingredients, and mix until everything is incorporated. Then mix in the chocolate chips.
Cover the bowl with plastic wrap and freeze the dough for 1 hour.
Once the dough has chilled, preheat the oven to 350 degrees and line a baking pan with parchment paper.
Portion into 12 medium-large cookies. Roll each into a round ball then press down gently with the palm of your hand to flatten to tops. The cookies will not spread much.
Bake for 12-15 minutes. Let cookies cool and firm up for 10 minutes on baking tray.
Drizzle more melted chocolate chips over the top of cookies, and sprinkle with crushed candy canes. Enjoy!
