In a medium bowl, whisk together the melted unsalted butter, minced garlic, smoked paprika, onion powder, chili powder, ground cumin, salt, and black pepper.

Add cubed chicken to the marinade, ensuring each piece is evenly coated. Cover and refrigerate for at least 30 minutes.

Preheat your grill to medium-high heat (375°F to 400°F) and soak wooden skewers in water.

Thread marinated chicken pieces onto the soaked skewers, leaving space for even cooking.

Grill the skewers for about 4-5 minutes on each side until charred and cooked through (internal temperature of 165°F).

Brush with remaining melted butter and garnish with fresh parsley before serving.
