In a large mixing bowl, whisk together the egg whites with the vanilla extract until the mixture is combined and frothy (1-2 minutes). Then stir in pecans until they are evenly coated.

In a separate bowl, stir together the sugar, brown sugar and ground cinnamon until well combined.  Pour this cinnamon and sugar mixture on top of the pecans and toss so that the pecans are fully coated with the sugar mixture.

Spray the crock pot with non-stick cooking spray and then add the pecan mixture to the crock pot.

Cover and cook on low for 3 hours, stirring every 30 minutes.

Stir the water into the crock pot for the last 30 minutes of the cook time to make the outer shell nice and crunchy.

Then spread the candied pecans out on a baking sheet and allow them to cool for 20-30 minutes.

Then the pecans are ready to serve, store or enjoy!
