Stir all ingredients except the walnuts together in a medium sized bowl until everything is combined. Then, add in the walnuts and stir until walnuts are evenly coated.
Oven Instructions: Spread walnuts in a single layer on a baking sheet lined with parchment paper or lightly greased. Bake at 250°F for 30-40 minutes, until golden and crisp. Be sure to stir halfway through and periodically check on walnuts to ensure they don't burn. Take walnuts out of the oven and let cool completely before eating.
Air Fryer Instructions: Add glazed walnuts to a parchment lined air fryer basket and air fry for 12-14 minutes at 250 degrees. Check on them halfway through to stir and ensure they don't burn. Once done cooking, let them cool in the air fryer basket completely before enjoying.
