In a small bowl, mix together the Berbere spice, maple syrup, and fine sea salt.
Place the chicken wings in a gallon freezer bag and pour the marinade over the top.
Seal the bag tightly, massaging the marinade into the chicken.
Let the wings marinate in the refrigerator for at least 4 hours, or overnight for even more flavor.
Preheat your oven to 350°F (180°C).
Line a rimmed baking sheet with aluminum foil and set a wire rack inside.
Remove the chicken wings from the marinade, shaking off any excess, and arrange them in a single layer on the rack.
Bake for 40 to 50 minutes, or until the wings are fully cooked through.
Pour the reserved marinade into a skillet over medium-high heat and bring it to a gentle simmer.
Add the cooked wings into the skillet and toss until the marinade thickens into a sticky glaze.
Transfer the glazed wings to a serving plate and sprinkle with chopped chives for garnish.
