Preheat oven to 350 F. Lay parchment paper or grease a large baking sheet.
In a small bowl, mix ground flax seeds and warm water. Let sit for 5 minutes, or until gelled.
In a large bowl, cream together vegan butter and sugar.
In a medium bowl, whisk together almond flour, all-purpose flour, cocoa powder, salt, baking soda, and baking powder.
Add flour mixture to the creamed vegan butter and sugar, along with the flax egg, peppermint extract and chocolate chips. Mix until combined.
Spoon cookie dough mixture onto the lined baking sheet (about 3 tbsp per cookie). The recipe should make about 12 cookies.
Bake for 10-11 minutes, until edges look cooked but not burnt. Remove from oven, sprinkle crushed candy canes on top, and let the cookies cool on the baking sheet. Serve and enjoy!
