For baked doughnuts, clean release is closely connected with product appearance. If dough sticks around the cavity or center opening, the finished product can lose its shape during removal.

A suitable nonstick surface can make demolding easier and reduce the amount of residue left behind. However, coating selection should also consider the intended baking temperature, recipe characteristics, cleaning method, and expected frequency of use. Bakeware guidance also emphasizes following the manufacturer's use and care instructions because materials and coatings respond differently to operating conditions.
