Start by patting the wings completely dry with paper towels, since any extra moisture will stop the skin from crisping properly in the oven. Place them in a large bowl and toss with the baking powder, salt, pepper, smoked paprika, and garlic powder until every piece is evenly coated. This dry coating is what gives you that shatteringly crisp skin later.
Set a wire rack inside a foil-lined baking sheet, then arrange the wings in a single layer without letting them touch. Spacing them out lets hot air circulate around each wing so they crisp on every side. Skipping the rack and placing wings directly on the pan will leave you with soggy spots underneath.
Slide the tray into a 425 degree Fahrenheit oven and bake for about 25 minutes. Flip each wing over with tongs and bake for another 20 minutes so both sides turn golden and crisp. The wings should look dry, tight, and lightly browned before you move to the glaze.
While the wings bake, whisk the barbecue sauce, honey, brown sugar, apple cider vinegar, and liquid smoke together in a small saucepan. Warm the mixture over low heat for a few minutes just until the sugar dissolves and everything turns glossy. This gentle heating step helps the glaze cling to the wings instead of just sliding off.
Once the wings are crisp, brush them generously with the warm glaze on all sides using your basting brush. Switch the oven to broil and return the wings for 2 to 3 minutes, watching closely so the sugar caramelizes instead of burning. You're looking for a deep, glossy, slightly charred finish that makes the glaze taste almost candied.
Pull the wings out and let them rest for a couple of minutes so the sticky glaze can set slightly before you dig in. This short rest also keeps the glaze on the wings instead of all over your plate. Serve them warm while that glaze is still glossy and a little tacky to the touch.
