Whisk all of the sauce ingredients together in a medium saucepan until well combined.
Bring to a boil over medium-high heat, stirring occasionally.
Reduce the heat to medium-low and simmer for 15–20 minutes, stirring occasionally, until the sauce has thickened and reduced by about half.
Remove from the heat and let cool for 3–5 minutes.
Toss with cooked chicken wings until evenly coated.
Garnish with chopped fresh parsley, if desired, and serve immediately.
Notes
If the sauce becomes too thick, you can thin it out with a little water or additional pineapple juice.If you prefer a less sweet sauce, reduce the brown sugar to 1/4 cup or use honey instead for a different flavor profile.
