1. In a large mixing bowl, combine the finely chopped pecans, graham cracker crumbs, and powdered sugar. Stir until well mixed.
2. In a separate bowl, whisk together the dark corn syrup, melted butter, vanilla extract, ground cinnamon, and a pinch of salt.
3. Pour the wet ingredients into the dry ingredients, mixing thoroughly until the mixture is well combined and sticky.
4. Using your hands, form the mixture into small balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
5. Chill the pecan pie balls in the refrigerator for at least 1 hour to let them set. This allows the flavors to meld together beautifully.
6. Before serving, you can roll the chilled balls in additional powdered sugar or finely chopped pecans for extra texture and flavor.

Pro tip from my kitchen: To make the process easier, lightly oil your hands before rolling the mixture—this keeps the sticky mess to a minimum!
