Add the walnuts and pecans to the food processor and pulse for 30 seconds.
Add the shredded carrots, dates and cinnamon and pulse until a smooth, dough-like consistency forms. You may have to press the sides down in the food processor periodically to make sure it is processing.
Roll the dough into balls, then flatten with a fork.
Melt coconut butter (or nut butter) and drizzle over the top.
