Preheat the oven to 350 degrees F and line a large baking sheet with parchment paper.
In a large bowl, add all the ingredients, including your flax eggs (once rested for 5 mins) and mix well. The batter will be thick and sticky. Use a large fork to help incorporate the ingredients.
Using slightly wet hands, form approx. 1” balls with the batter and pace them on your baking sheet, leaving plenty of space in between each one. Keep wetting your hands every few cookies or so, to prevent the batter from sticking to your hands, and to help form the balls. Press each one down slightly using your fingers.
Bake for 10 minutes, remove from the oven and allow the cookies to cool for at least 10 minutes before handling.
Press the crushed candy cane into your cookies, if using.
