Preheat the oven to 375 degrees F (190 degrees C).

Arrange chicken wings evenly on a baking sheet.

Bake in the preheated oven until crisp, 35 to 45 minutes. Transfer wings to a baking dish and set aside.

Mix together 2 1/2 cups water, brown sugar, soy sauce, honey, garlic, and ginger in a medium saucepan over medium-high heat; bring to a boil. Whisk together remaining 3/4 cup water and cornstarch in a small bowl until smooth; stir into soy sauce mixture and cook until thickened. Pour sauce over chicken wings to coat.

Return wings to the oven and bake until sauce is bubbling and chicken is no longer pink at the bone and the juices run clear, 15 to 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
